So having found my access to RL 15 being 0, like everyone else, I suppose, looking for alternatives. I talked with Barnes this morning and they gave me some load data to consider. BTW, their favorite was RL 15, of course!

So what is your favorite second choice for 250-260 grain bullets? 4064? What about it's temp stability? Viht 540? Something else entirely?

IMR 4064 is hard to beat in a 375 H&H with any bullet weight. Lots of powders in this burn rate range to choose from.

Other powders I have used are IMR4064, IMR4320 and W760. I just found RL15 Saturday at a local shop and they had also just gotten in several different IMR powders including 4064.

I use Varget with 270 gr. TSX.

On the RL 15, I can't find any locally. I don't even know where to order it from, although there 'might' be some in Houston.

4064, I can get. It was also on the list of the loads Barnes sent me for their 250 TTSX. Their favorite powder was RL 15, but they liked 4064 as well.

How about temp sensitivity? I had thought 4064 more sensitive than RL 15, but am now reading different on sites.

Barnes data with N540 was pretty impressive, but it comes with an impressive cost as well, and don't know it's sensitivity.

On my last PG hunt I used 250gr North Fork bonded cores with H4895 for 2850fps and great accuracy. Temp sensitivity from load development in the winter to warm temps in May prior to leaving was a non-issue.

I was able to duplicate that MV and accuracy with Varget, but pressure signs were starting to show.

R-17

I have the same dilemma. I've been starting to buy 4064. I don't know what the deal is. between Cabelas, Scheels, Runnings, and two other local reloading store, I haven't seen RL15 in over 6 months and I refuse to pay the insane shipping charges for powder. I also haven't seen any pistol powders in any of these stores in over 6 months

Cabelas in Lacey had 11 pounds of RL15 on Thursday.

maybe they can send some to the rapid city cabelas

Reloader 15 works great with the 300 grain Barnes Banded Solids but nothing beats 67 grains of IMR4064 with the 300 grain Barnes TSX out of my Model 70.

I have never used anything but IMR4350 but then I have never used any bullets but Nosler Partitions in my 375's. Never had need for more and have taken most everything with it and them except Elephant and for that I used Woodleigh 300gr solids but used IMR4350. Why argue with success.

RL 17 I can get. What loads are you using?

I hear alot about North Forks, but I have never seen them. Are they still made?

Yes sir, just picked up a box at their DSC booth.

I am looking at using the NF 250 grain bullet for Elk next fall. How was the accuracy beyond 300 yards?

The 375H&H is one of those cartridges that work with just about any components you care to use. I wouldn't sweat 50fps one way or the other.

I am not recommending this...but if it were me...I would start around 75 gr and work up.

Also use IMR 4350, especially for .375 flanged magnum and IMR 4895 for my rimless bolt gun.

Regards

IMR 4350 and R-17 are very close.

I use H335. Works Great!

Winchester 760 gets very good velocity in the 375 H & H

I would start lower with 300 grain bullets and RL 17. I get 2480 FPS from a 22" bbl with 73 grains and a 300 gr NF solid. 75 would be the limit in that gun.

Yes...me too.

But he was asking for 250-260's.

my 375 H&H like H414 (aka W760) almost as much as RL-15

Right, just trying to eliminate any possible confusion as the first post in the Kifaru link had data for 300 grain bullets.

Sorry tanks, I've not shot these beyond 300 yards so I can't tell you.

Some of you have mentioned 4064. Is there any benefit to RL15 or 760 or others over 4064? I gather it was the favorite for the 375 at one time but has been mainly supplanted by RL15. Any reason why?

I ask because 4064 I can get....

Have always used 4064, but then I started loading many years ago and have stayed with what worked when I first bought the rifle and did load work.

I also started with 4064 back in the 80's but went to RL15 & H414 to reduce my powder inventory. I have other rifles that also love RL15 & H414. I love the way H414 meters.

Last load up was 83gr. IMR 4350, Speer 235's. Accurate and easy to shoot in the Sako manlicher carbine.

I found some very good loads with RL 17 and 300 TSX bullets

h335, from 22h - 550 magnum

Some work I did with Reloder 17 and 270gn Woodleighs here. Works nicely in the .375 and might help you with a starting load. Need to read right through to the end of the thread as there are a few off topic posts.
FYI "Uncle Nick" is Nick Harvey, a prominent Australian gunwriter who has published a series of reloading manuals. AR 2209 is sold in the U.S. as H4350.

Also tried it with the 300gn Barnes TSX.

IMR 4320 with 270 Failsafes. Good accuracy and nearly 2800 fps at my altitude of 6800+ ft.

Know of any 270 grain Failsafes for sale?

4064 peters out faster over distance. Ask RIP.

I use H 4895 in my RSM. Shoots sub MOA with Barnes TSX & Barnes Solids.

IMR 4350 is old school but a caseful has worked very well with 300 grain bullets in the 375 H&H for many years. I've shot tons of game with this load and it has worked perfectly.

The 375 is so easy to load and the options are endless...4064, 4350,H4831,H414,Varget,4320, and a host of others will get you over 2500 FPS with 300 gr. bullets...I think you could load that old bird with talcum powder and get 2500 FPS and good accuracy...

I have sorta settled on RL-15, IMR-4064, and IMR 4350 over the years, depending on what a particular gun likes best.....I really don't want a 300 gr. bullet going faster than 2500 FPS for DG in Africa, or even for elk in Idaho for that matter.
