Re: Lightweight .375H&H bullet results?

The 375 H&H is my all around hunting cartridge.

While I primarily shoot 300s, I also have fun with the 250 grain Sierra bullets. They are quite accurate in my old pre-64 M70 and make great practice chasing jackrabbits and coyotes.

I have tried the Speer 235s, however, I cannot get a load worked up that will stay under 1.5" @ 100. May be the long throat.

I've been carrying a 375 for more years than a lot of "experts" have been hunting and I'll load it with whatever I want!

Play around and have a good time. It is the most versatile cartridge, in my opinion.

Oh, and don't forget to try your hand on some prairie dogs with the 250s....they generally stay down pretty good!

What about the 260 grain AccuBond? It has a high BC and is significantly more aerodynamic than the 250 Sierra. Following Dave's lead of "what ifs", I ran some available information through a ballistic program and came up with these results:

BC = 0.473
Muzzle velocity = 2900+(at working pressure)
250 yard zero yields:
+2.7" high @ 100 yards/2717 ft.lbs.
-35.6" low @ 500 yards/2008 " "
-102.7" low @ 700 yards/1669 " "
-218.5" low @ 900 yards/1183 " "
-301.9" low @ 1000 yards/1001 " "

I'm waiting for the GS Custom site to come back up so that I can get some information about the HV .375 bullets. I have used some of their .338's and 30 cal. with very good results and they come with a fairly high BC.

Re: Lightweight .375H&H bullet results?

Thanks, that's just the sort of advice I'm looking for. I've been loading groove bullets - which weigh 271 grains on my scale, the Groove bullet website lists a BC of .401 and a SD of .29

My load is 66.5 garins of Alliant's Reloader 15. I also loaded up a few test rounds with 75 grains of IMR 4350, but that is a slightly compressed load so I'm maxed out in case capacity even though it is at the book minimum load.

If you could give any info from the software on those loads I would appreciate it greatly too!

Re: Lightweight .375H&H bullet results?

How incredibly refreshing to find that I'm not the only one with long range aspirations who has a lot to learn!

I am not a competitive shooter and my shots on game are well under 300 yards, but there is something in me that demands the ability to someday hit milk jugs at 600.

Beyond that, I want to do it with my hunting rifles (a factory stocked 375 H&H Win M70 topped with Leupold VariII 3-9).

The hold over for a 375 H&H factory load is obscene past 300 yards, so I have made the mental leap to the idea of loading lighter projectiles in an attempt to flatten trajectories.

I know nothing about ballistic coefficients etc. and while I would love to eventually reach the state where I am comfortable shooting at game beyond 300 yards, at this point I am just plinking at long range.

I see that Speer makes a 200 grain bullet that sells for about $11/50. If memory serves Barnes makes a 210 grain premium bullet that might be just dandy for white tail too. For cheap plinking I see that Bullet Barn just introduced a 375 caliber lead bullet that retails for $29 per 200 ct. Not sure about the accuracy potential of a gas checked lead bullet but at that price it's worth a try. Now if I could just find cheaper powder source....

I've been loading R-15, but a full case of R-15 in each cartridge eats a pound of powder about every 100 shots. Any suggestions?

In fact, I'd welcome any input on tuning the 375 H&H Winchester M70 into a long range rig. This is too good an idea not spend a summer's range sessions exploring.

Mike I do a lot of shooting with a 210gn Barnes X in .375H&H, I load it over 73gn of H4895 or VV N140, still 73gn.

Gives gives 3000fps exactly, while still being (apparently) fairly light in my rifle.
You could most likely go faster but I odn't think you'd gain much.
Tradjectory is not great as these bullets have a BC .341.

I used it for moose in Canada and I use it on deer and pigs here where I live with very good results.

Wow! 3000 fps!

What is the drop like for that load?

Re: Lightweight .375H&H bullet results?


I've got this Ruger Mag in 416WBY I shoot (not so much lately) at LR, out to 700 yards for the most part. I'm switching to lighter bullets this year, benn shooting the 400 XLC, but have some GS Custom 330gr HV's to try out. I'll drop to 350's or 300's and try them in the Barnes if they don't work, or I can't get any more from 330's GSC.

The .375 260gr Accubond should be a sweet bullet for LR.

The 210 or 235gr should go 3000 pretty easy, maybe 3100 or faster with the 210 I'd think.
