Powder for 375 Ruger 270 Barnes LRX

[generalzip]

Did some chrono work today myself. Using my Ruger African.
300gr TSX
73.3gr Win760
Coal 3.333"
1- 2568
2- 2542

300gr Gameking
81.0gr RL19
Fired only one 2467

235gr Hotcors
79.3 RL15
3.31"
1- 3013
2- 3020
3- 2977

My reduced load:
300gr Interlock RN
60gr RL16
3.29"
1- 1968

Not bad. Try the rl16 in your full loads with the 300gr. You much be happily surprised. Also curious with your reduced load. If you went to a lighter bullet I’m willing to be you’ll see less recoil and better velocity which will help with expansion. 2000 fps is on the cusp of minimum expansion velocity especially at 100-150 yards. I’d use the 235 in your reduced load and see what you get. Just my .02

Guess you don’t read much? I made a post about that exact data…

You said you found Speer data, I was showing you Sierra.

Ok, found some Speer data for 375 Ruger and RL16. Other than its temperature stability, one other nice thing about Big Game is how the spherical grains pack into a case with little or no compression.

The 300 grain round nose reduced, is just for whitetail deer. Don’t really need the expansion when your bullet starts out the size of an expanded .243 bullet lol

@jaycee just wanted you to know I wasn't being a smart @$$ by what I said. I have some more RL16 data I can share with you too.

Oh year deer are easy to kill. I just grab my 6.5 CM for them.

I'll definitely play around with different combinations. What really surprised me was the RL19 load. I didn't expect it to work so well.

Thanks for posting that - in hindsight I guess I was being a little thin skinned.

Rl19 is a fast powder in 375 Ruger for sure. Since you’re using shorter lead bullets compared to my copper ones I suspect you can get enough rl16 in the case to realllly get it moving without too much compression. Rl16 is also pretty temp insensitive especially compared to rl19 which is a big plus for me as this rifle will be used in Africa as well as cold climates.

19 is actually too slow, thats why I was shocked. We RL17, I had 300 grain bullets going over 2700. It showed no pressure signs, but I knew it was too far. Recoil was stout.

With RL16 I'm actually limited by the amount of powder I can stuff in the case. The all copper bullets a longer than lead ones. I think a 270 or 300 grain lead bullet I'd be able to stuff even more powder into it and reach around 2850 or so.
