I've been working on loads for my upcoming Buffalo hunt using Barnes 350 Tripplshock and North Fork 370 Flat Point bullets. After trying different ammounts of Rel 15 I found the sweet spot. If I use 84 grains for the Barnes (2600 fps) and 83 grains for the North Fork they hit in the same spot at 100 yards. I just finished shooting a 7 shot group, 4 Barnes and 3 North Forks and ended up with a 1 1/4" group. That's about as good as I can shoot after 40 rounds in one day. The next step is to chrono the North Fork, it was hitting 2400 fps with 78 grains of Rel 15, my guess is in the neighborhood of 2600. It's just for curiousity cause I've heard good reports using this bullet on game at 2400. The 350 Trippleshot was chosen over the 400 version to gain a little speed and flatten the trajectory. Using Barnes BC that combination should be comprable to a 180 grain spitzer out of a 3006, thus giving me an option for plains game on the far side of 200 meters. Now for some practice from field positions.

Nice shooting.
Great study, too.

Kick ass and take names.

Maybee leeeetle too much powder, Quickstraw. Check on a hot day with ammo sitting on dash for two or three hours before trip.

Just a thought.

Maybe.... Maybe not! Every rifle is different and we must always be aware of excess pressure. Saftey must always come first.

I use 85 gr of Rel 15 to push 350 Swift A Frames. This is wrapped in Remington Brass with Federal 215 primers. Average velocity is 2617 fps.

Been using this load for 5 years and has been to Africa twice. Never any problems.

Thanks for the concern over heat, it occurred to me too. Today it was 90f when I got home from work, so I let some ammo cook for a couple of hours while I bushhoged a field. When I got arround to shooting it had dropped to 88 but after 8 shots there were no presure signs, of course that doesn't mean they weren't high, just that I was able to shoot and extract them with no trouble or primer problems. One of Barnes engineers e-mailed me and gave the go ahead with these loads providing they didn't show any signs. For the record these loads were with Remington brass, CCI magnum rifle primers, Rel 15, and the respective bullets.

Lewis50,

Sounds good to go.

Those are all good components.

Try not to have too much fun over there, ok?

Lewis50,
I think you could have saved yourself some time and trouble getting the two bullets to shoot to the same point of impact. That 350gr Barnes TS will take care of your buffalo needs. I used 270gr Barnes TS in my 375 H&H. No need for solids or other bullets. Good luck on your hunt.
