30 Caliber Mag FanGo to powder for .375 H&H????
Friends-
What would you consider a "go-to" powder for the .375 H&H?
Of course this may somewhat depend on bullet weight, so, what powders would you consider the best for either 270 grain or 300 grain bullets?
Thanks in advance.
May the wind be in your face and the sun at your back.

GrumulkinThat would be RL-15.

PatagonHunterHello 30 CMF,
I use and reload for a .375 from 20 years ago.
For this two bullet weight, if you want only one powder, I chose any of the 4350. By far. For the 300 grs and heavier, is the perfect powder.
For the 270 both the 4350 and R15 are great. For lighter than 270 grs bullets, R15 alone is the powder.
My experience.
Regards,
PH

Oday450+1 on the RL 15. 74 gr RL 15 + 270 gr TSX will drive tacks in my rifle.

TumbleweedDepending on bullets, I like both RL 15 and WW 760....but 67 gr. of IMR 4064 under 300 gr. Barnes TSX is unbeatable in my rifles.

RhysMine doesn't much care for RL-15, but Varget has done very well.
Yes it's cocked, and it has bullets too!!!

Blacktailer++ RL15 although the 375 H&H seems to do well on almost anything.

craigsterIMR 4064 and 4895 are the go to's for me, have always provided great accuracy with most all bullets I have used.

NFMike760/414 will do whatever RE15 will do and at considerably less pressure. Or you can get another 50 to 75 fps at the same pressure. Without doubt, my new favorite is RE17 for 300 and heavier slugs. It beat 760, H4350, and Re15.

BuliwyfIMR 4350.

67.5 grains of IMR4064 and the 300 grain TSX shoots like the Hammer of God in mine.

DUKVihta N140 works well with Barnes TSX 300 grain bullets.
03 November 2009, 12:07
GerryI use VVN-160 for the Hornady 300 gr. RN's and an increased charge of the same VVN-160 for the very few Nosler 260 gr. AB's I load.
Did I mention VVN-160 was a good .375H&H powder?
Second place when supplies of VVN-160 are low is H-4350.
Have fun loading your .375H&H.
Cheers,
Number 10

It also works very well in my rifle for the 260 grain Nosler Accubond bullet.

StonecreekHard to beat IMR-4350. I think there is even a short cut version now available, which would be even better. I have also used H-414/WW760 successfully.
06 November 2009, 20:02
jstevensI have always said RL15 or 4064 in mine, but a lot of guys swear by H414. It certainly works well in pretty much anything else.

greenjoyFor 300gr bullets I favour H4350 (not the IMR version) the best.
For 270gr to 250gr bullets R15 is the powder of my choice.
For 235 or lighter BL-C(2) really makes them move faster with lower pressure.
Stay tuned we just maybe on the horizon of a new era of powders, as a new generation of powder making chemical engineers decide to prove their worth and push the technology beyond what was ok for WWII. Powder companies had decades of resting on the laurels of those engineer that went into retirement long ago.

JMeierAnother vote for R15.

Alberta CanuckMy "go to"powder for the .375 H&H is IMR or any other 4350 for any and every bullet weight.
First off, I don't care which powder gives the maximum velocity. I am not after absolute maximum velocity. I AM after relatively consistent velocity from lot to lot and make to make.
By not operating at red-hot-moma pressures, I can use the same charge (for a given bullet weight) of just about any lot or any brand of 4350 that I can lay my hands on.
Especially these days, that has turned out to be pretty handy. And, as there are numerous sources of 4350 out there, pretty much all over the world, I can usually find some at a pretty decent price from stores, major suppliers, friends, clearance sales, garage sales, even estate sales.
Works for me. YMMV.

LE270A compressed load of H 4350, in Winchester brass with Winchester Large Rifle (NOT magnum) primers. With this I can get about 100 f.p.s. more velocity than most published loads for 270 and 300 grain bullets, and with excellent accuracy.
Note: This is Hodgdon 4350; NOT IMR 4350.

JBrownI really like ww760 for 300 gr bullets and RE15 for the 270gr.
AA4350 also gave me good results.

Never under estimate the internet community's ability to reply to your post with their personal rant about their tangentially related, single occurrence issue.
What I have learned on AR, since 2001:
1. The proper answer to: Where is the best place in town to get a steak dinner? is…You should go to Mel's Diner and get the fried chicken.
2. Big game animals can tell the difference between .015 of an inch in diameter, 15 grains of bullet weight, and 150 fps.
3. There is a difference in the performance of two identical projectiles launched at the same velocity if they came from different cartridges.
4. While a double rifle is the perfect DGR, every 375HH bolt gun needs to be modified to carry at least 5 down.
5. While a floor plate and detachable box magazine both use a mechanical latch, only the floor plate latch is reliable. Disregard the fact that every modern military rifle uses a detachable box magazine.
6. The Remington 700 is unreliable regardless of the fact it is the basis of the USMC M40 sniper rifle for 40+ years with no changes to the receiver or extractor and is the choice of more military and law enforcement sniper units than any other rifle.
7. PF actions are not suitable for a DGR and it is irrelevant that the M1, M14, M16, & AK47 which were designed for hunting men that can shoot back are all PF actions.
8. 95 deg F in Africa is different than 95 deg F in TX or CA and that is why you must worry about ammunition temperature in Africa (even though most safaris take place in winter) but not in TX or in CA.
9. The size of a ding in a gun's finish doesn't matter, what matters is whether it’s a safe ding or not.
10. 1 in a row is a trend, 2 in a row is statistically significant, and 3 in a row is an irrefutable fact.
11. Never buy a WSM or RCM cartridge for a safari rifle or your go to rifle in the USA because if they lose your ammo you can't find replacement ammo but don't worry 280 Rem, 338-06, 35 Whelen, and all Weatherby cartridges abound in Africa and back country stores.
12. A well hit animal can run 75 yds. in the open and suddenly drop with no initial blood trail, but the one I shot from 200 yds. away that ran 10 yds. and disappeared into a thicket and was not found was lost because the bullet penciled thru. I am 100% certain of this even though I have no physical evidence.
13. A 300 Win Mag is a 500 yard elk cartridge but a 308 Win is not a 300 yard elk cartridge even though the same bullet is travelling at the same velocity at those respective distances.

ozhunterH4350 which is the Australian AR2209 which is great for extreme temperatures.
