I just finished load development for my .375 AI, which I will use again this and every year. The load is with Barnes 270 grain LRX’s a bit over 3000 mv @ 90+ F temps. Likely a bit slower at fall hunting temps!

Here is a photo of a test target…..2 groups fired, 2 days apart, with one grain difference in powder charges. The group outlined in red went 1/2” center to center…. and only had 3 fps velocity difference high to low velocities! The group “might” have been a tiny bit smaller, but I didn’t allow any cooldown between shots…..shot them as fast as I could record the velocities and set-up for the next shot!

So, once zero’d……..”I think that this dog will hunt”! memtb
