Howdy,

My 375 WBY shoots the 300 TSX very well with H4350. I'd like to work up a solid bullet load also preferably with the 300 Barnes Banded Solid. Anyone have expereince trying to get these two bullets to shoot to the same POI?

Mark

I would drop the powder charge 4 or 5 grains and work up, watching point of impact.

If it gets farther apart as you go up, then go down a grain at a time from your TSX load.

Mark, don't know about the Weatherby, but in the 375 H&H, one can get both to shoot to POA easily....with the Banded solid loaded about 2 gr or so lower depending on the rifle.

Good luck.

This 375 Weatherby has to be the one of the easiest to load rifles I've had. 86 gr H4350 with the 300 TSX as RIP suggested shoots like a house a fire (.50"-.75"). Same load with Barnes Super solids hit exactly 1" higher. My load development is over. Both loads are clocking about 2725 fps. I'm sure I could get 50 fps more but why bother. So my experinece is that the 375 Weatherby will beat the H&H by 200 fps or at least it beats my H%H by that margin. The gain does come at a cost of a noticealbe increase in Recoil.

Mark,
You are doing the same thing with your .375 Wby as Saeed does with his .375/404.
But you can also shoot plain vanilla .375 H&H loads in your .375 Wby,
and Doctari would approve of the effectiveness of those too.
Jolly good show!

I've done the same with my 375 Ackley Improved. Quit at 84 grains of H4350 (Chrono'd at 2692fps) because the Accuracy with Fail Safes was 1 1/8". I may experiment some more now with Barnes Bullets and see what I can do.

Dang it all, I thought I was through fooling with .375 Wby loads. I have some H4350 I thought I'd try in my .280 Rem instead of IMR 4350 (which I couldn't find). Not as good as IMR there but now I have to use the rest up.

Oh, my 300 grain Barnes (non-banded) solid load uses 87 grains H4831SC.

Mark,

My experience has been with the H&H non-AI and it does very well with the TSX/Solid combo. But I only used RL15. Here are my results:

TSX
70gr. RL15 - 2599fps
71gr. - 2611
72gr. - 2665

Solid
70gr. - 2598
71gr. - 2630
72gr. - 2665

These were tested on 7/22 at 85 degrees (early on a hot AL day). I've since shot the 71gr. load for groups with both bullets and it does very well. Chrono testing with these and the 350gr. Woody bullet showed 5 rounds of each, solid and soft, total of 20, printing into a 2" circle at 100 yds. I consider myself very lucky here, but think it to be very doable by anyone. The H&H and offspring seem to be very easy to load for.

David,

This reloading stuff is always interesting. My 375 H&H will run faster but beyond 2540 FPS I loose my accuracy. Your rifle is definitely a screamer.

Mark

.375 H&H with 73 grains of R-15 shooting a 300 grain TSX out of a LH Model 70 @ 2550 fps and 71 grains R-15 with a 300 grain Barnes banded solid shoot to within 1 inch of each other (the solids impact higher), both one inch loads if I do my part.
