Product Overview

Hodgdon H4350 Extreme Extruded propellant is a burning speed that has been known to shooters for decades. During that time, Hodgdon has modernized H4350 by shortening the grains for improved metering and making it insensitive to hot/cold temperatures. H4350 is ideal in the WSM family of calibers (270, 7mm, 30, 325). H4350 is the standard in such cartridges as the 243 Winchester, 6mm Remington, 270 Winchester, 338 Winchester Magnum and many more. For magnums with light to moderate weight bullets, it can’t be beat!

    this stuff is dynamite! keeping my loads within .1 grain of each other, my shots were all within +/- 12fps of each other. I was putting my shots thru the same hole! I was also able to develop3000fps w/ 155gr Amax bullets w/o coming close to the max loads from the load data in my reloading manuals. FANTASTIC!

    I use H4350 in my Rem 700, 30-06 for 17 years. If my heart is not beating too hard that morning, I can put 10 bullet holes touching, so if youre looking for accuracy, you can’t beat it. I can shoot consistently out to 500 yards with it. The MOA is a bit slower, add an additional 20 seconds of MOA for every 100 yards to the target. Best shot was 485 yards and I pulled a white tails heart out.

    One of the most preferred powders I use, slow burning so low “felt” recoil for grandsons. Incredible accuracy when loaded to the right speed for your gun.

    Started using H4350 in 2002. In 308 Norma Mags and a 300 Win Mag. Used several different primers and power working these loads up. I had to deal with tempers from 60 to 105 degrees and watch high pressure signs develop with other powers within that temperature range. Used H4350 in Zero to 100 degrees and no high pressure signs at either temperature in the loads I developed. Pressure signs remained the same. Found in the 308 Norma Mag 24″ barrel Federal 215 worked best and group under 1″, with velocity of about 3200 fps. Found in 308 N. Mag 26″ barrel using Federal 210 primers and added 1.6 grains achieved under 1″ groups with velocity of 3300 fps. The 300 Win Mag in Ruger-1 achieved greater velocity of 3430 fps under 1″ groups using Fed 210 primers and more power. Using a Nosler green tip 165 Boat Tail. Be careful of using different primers, some are hotter than others and act differently along with different powers and bullet weights with temperature change. Watch your weight on rifle cases too. You have to work up your own hand loads You do need away to measure the velocity of your hand loads to really understand and know or tell what your loads are doing. That will take a lot of work out figuring out what the round should do down range. I point out H4350 out to other hand loaders all the time and difference in primers. Mike

    I am looking for a powder I can use for both .270 Winchester and 7mm-08 Remington. Maybe I am looking in the wrong place(s), but I can’t seem to find load data that shows H4350 will work for both. I am assuming it would seeing as loads and pressures are generally the same. I also see 7mm mag data. Anybody use to reload both and how have your results been?

    In reference to the other post on temperature sensitivity with this powder, I too have seen more than advertised velocity variation with H-4350. My load for a Tikka 243 Win was 100 gr Nosler partition, Win LR primer, H-4350. Using the same cases, powder, primers etc. I left the gun and shells outside over night. At 30 degrees it gave an average velocity of 2940 fps. Leaving gun and shells inside at 70 degrees gave an average of 2980 fps. Leaving gun and shells at 110 degrees for several hours still gave an average of 2980 fps. This is good, better than other brands of powders, mainly at 110 degrees. The fired primers looked about the same in all tests, ie the ones at 110 degrees were flattened the same as at 30 degrees. I called Hodgdon and asked Mike a tech. Interestingly enough he admitted that their tests are not done to represent the real world. They only cool or heat the loaded shell, not the gun. He said this truly tested the powder. My opinion is that may not be true. Having a gun at room temperature and the shells at 10 degrees or 100 degrees could give misleading results. The difference in the gun’s temperature may compensate for variation in the powder. What hunters and target shooters are interested in are real world results. In this regard they may have failed a bit (especially in their advertising.) Another similar test that I ran in a 7mm WSM with H-1000 powder showed almost no variation from 110 degrees down to 10 degrees. It was a compressed load with 160 gr Nosler Partition. I still maintain the Extreme powders are the best for velocity/pressure variation, especially at the high end of usable temperatures.

    My first time using this powder, I just looked at the load data for a 120gr TTSX and picked 42.1 gr of H4350. I put three shots into .271 inch. I think I found a new deer load for my Creedmoor. About 2800fps out of the barrel of my Savage Axis 2 with the heavy barrel. Mild recoil and it just seems so easy to shoot. Lookout whitetails. Thanks for having it in stock Gunsvalley.com .

    Great stuff

    I use this powder exclusively for long distance target shooting for 260 Remington and 6.5 Creedmoor. It’s consistent and meters really well from my Redding competition powder dispenser. I haven’t felt the need use anything different. If it ain’t broke, don’t fix it.

    I use H4350 for reloading Remington .260 cartridges with Lapua Scenar .139gr .264 bullets. Through extensive testing with many other powders designed for this usage I found H4350 gave me the most consistent velocity at a point where my gun is most accurate. Using H4350 gives me the confidence of knowing my gun is doing the best it can giving me the peace of mind to concentrate on the things I need to do as a shooter.

  11. clientservice

    Great powder for 6.5 Grendel and 6.5×55 swede.

  12. clientservice

    This product is very predictable.

  13. clientservice

    I have two powders that I use for my 30-06 loads with this being one of them. This one is probably my favorite due to the varied range of temperatures that I shoot in. Very consistent!

  14. clientservice

    Tried them all but everyone knows 4350 is king. I use exclusively for 6.5crd

  15. clientservice

    Most accurate using 220 gr. Swift A-Frame on 325 WSM

  16. clientservice

    f you reload 6.5 Creedmoor, you owe to yourself to try this powder. It is a real group shrinker. The 6.5 and H4350 were made for each other. This is one powder that I try to make sure that I never run out of.

  17. clientservice

    One of my best performing recipes is with this powder. 6.5 Creedmoor is excellent as an accurate round, but with this powder coupled with Starline brass and 140 GRAIN ELD’s is a great combo…

  18. clientservice

    Perfect powder for the Springfield 30-06. Have worked up loads, and experimented a good amount with this powder. I am very pleased. Works better than expected. A staple of the reloading bench now!

  19. clientservice

    I have been shooting 4350 for years and it has always preformed well.

  20. clientservice

    Use it in my 269 rem. Working on loads right. Shot .462 5 shot group out of savage model 110 desert tactical with 123 Sierra mk. Now working on load for the 142 km and 140 hornady match

  21. clientservice

    I use the Hodgdon H4350 powder with the .264 Hornady ELD match rounds to get consistent accuracy out to 1250 yards. I would recommend it too anyone that hand loads for consistent accuracy.

  22. clientservice

    Perfect powder for my 6.5 creedmore

  23. clientservice

    I use 4350 with 140 gr ELD M in my 6.5 creedmoor RPR and AR 10 helps me keep my shots in the X and 10 ring at 600 yards

  25. clientservice

    reloading for 270 ,great results

  26. clientservice

    From personal experience and from further investigation on reloading forums, H4350 seems to be the clear choice for 260 Rem gassers.

  27. clientservice

    I would recommend to a friend

  28. clientservice

    best all around rifle powder there is! completely temperature stable,lot to lot consistency and best accuracy.I use it for 6mm creedmoor,6.5 creedmoor,.270 win.,.30-06sprg.,.280rem., 280a.i.,and .300wsm all with great results also it’s clean burning,I use a stainless steel tumbler with water and you can see the difference between this and other powders when you drain the water.

  29. clientservice

    One of the best multiple caliber powders on the market.

  30. clientservice

    Since many consider this to be THE powder for the 6.5 Creedmoor, I decided to try it. I easily found a load my Creedmoor likes. 3 shot 300yd groups of 1.5″. 5 shot 300yd groups of 2″. For me, that’s great, so I bought a 2nd jug to ensure I have enough on hand to possibly wear out my barrel. Thompson Center LRR, 42.0GR H4350, HORNADY BRASS, CCI 200, HORNADY 140GR BTHP MATCH, 2.825″ OAL, 2736FPS AVERAGE AT 10′ AND 70 DEGREES (start lower and work up!)

  31. clientservice

    Use to reload Hornady 140ge ELD-M bullets for my6.5 Creedmore. 5 shot groups average at or under1/2″ at 100 yards.

  32. clientservice

    Very versatile & gives stable velocities in 6.5mm & 6mm Creedmoor. Also works well in 6mm Norma BR & 6mm Hagar. Meters far better than I expected for a stick powder.

  33. clientservice

    This is a great powder good to use. For match grad ammo really good at getting the Muzzle velocity you’re looking for

  34. clientservice

    Very universal powder it works in lots of different calibers

  35. clientservice

    Works great in my 6.5 Creedmoor

  36. clientservice

    This was great 6.5 Creedmoor powder. Great loads. Sub MOA

  37. clientservice

    Have been using H4350 for years in 1lb containers. This is my 1st venture to an 8 lb container. If any thing, the 8 lb should help w consistency. The powder itself (H4350) has given me some of my most accurate loads for my 6 MM (75/85 gr), 260 (123 gr), 30-06 (165 gr)and 300 H&H 165 (gr). It has been best for me w mid-weight bullets per caliber.

  38. clientservice

    This powder works great.

  39. clientservice

    I have been reloading since about the early 70’s . I have used most powders . and I keep comeing back to 4350 . because it preformes the best in all of my bolt action guns . 1 25/06 1 270 wsm 1 7mm/08 1 270 win . I get the best performance from 4350 . I would greatly recomened this powder . it realy works !!!!!

    I have started using the H4350 powder almost exclusively when loading 6.5 Creedmoor precision rounds. This powder has worked well (consistent) under varying environmental conditions as compared to other powders I use. I have found that loads utilizing 40.3 and 40.7 grains have produced the most consistent muzzle velocities, lowest standard deviation numbers and most consistent 100 yd. groups. For me, precision reloading is a work in progress, I’ll continue to use the H4350 until I find something that works better. Attached is a 100 and 300 yd. group using 40.7 grains of H4350, CCI BR2 Primers, 6.5 Creedmoor brass and Hornady 140 grain ELD bullets.

  41. clientservice

    When working up powder loads you always have to take into consideration the temp you are going to be hunting at. Why would you work up a load in the summer, you are going to use in the winter, and don’t chase velocities. That is the biggest mistakes bench new loaders make, faster is not always better. Just something I have learned over the years. I use 54.3grs of H4350 in my .270 pushing a 130gr Barnes TSX BT at 3120fps at 4500ft alt and hit postage stamps at 100yds. This is my 20 to 60 degree load

  42. clientservice

    Found this to be the best powder for 6.5mm short action cartridges such as 6.5CD or 260 Rem. Very accurate with acceptable velocity. Compared vs. H414, H100V, Varget, H4831sc, and others. Works well in many cartridges.

  43. clientservice

    I have always found this powder to be more consistently accurate than IMR-4350 in my rifles.
