BigUglyMan;
Congrats on your trophy! Very nice animal, and a well written story.
May I ask a couple questions?
I've been around the block a couple of times at nearly 76 and 60 yrs hunting, but, though I've owned and used most of the familiar cartridges in rifle hunting from .22 LR to .458WM, only recently did I purchase a T3 in 9.3 X 62. Right now it's being used (just began last Friday) in bear hunting (actually, I'm guiding a young hunter over bait and we have a big one coming), and the load is 58grs RL-15 behind a 286 Hornady in Hornady brass (really S&B) and ignited by WLRM primers. MV is 2400 + fps. It shoots into .75" at 100yds for 3 shots (consistently) It's zeroed at 100. The one bait is 70yds from my ladder stand.
Q. #1 -- how do you explain only 2350 fps from a 286gr Norma from 61.5grs RL-15? All that I've read and researched to date indicates 58 to 59.5grs as max.
Q. #2 -- is your barrel a shorty, and is your action and freebore extra long?
I've loaded 6 more with 59.5grs but haven't tried them yet because the current load is plenty, very accurate, and I'm thinking that even 59.5 may be too much. I'm also thinking that my next can of powder might be RL-17 after reading the results of a full test of that cartridge in a Ruger Hawkeye (23") on Real Guns.
Thanks for any help or suggestions.
And, BTW, the Hornady bullet is a good one, not the best, but very good. It's the same basic bullet as the 270gr in .375" loaded by Hornady for both the .375 H&H and the .375 Ruger (@ 2800+ from the Ruger) which has been used to flatten Cape buff with a single shot.
Here are the specs for each of those bullets:
.366/286gr:
Jacket: gilding metal
.030" -- tip to cannelure
.035" -- cannelure to base
.050" -- base
Core: lead + 3% antimony
.375/270gr:
Jacket: gilding metal
.030" -- tip to cannelure
.036" -- cannelure to base
.060" -- base
Core: lead + 3% antimony

Bob
