Seekins Precision PH3 300 PRC Copper loads

[stonecw]

I have a new Seekins Precision PH 3 in 300 PRC. 22 inch barrel with a 1/10 twist. I was wondering if anybody had worked up accurate loads using a Barnes LRX bullet. The 206 gr. Won’t work due to the twist rate.

I ran up a load with a 190 lrx that was just under 1”, I tried n565 and magpro along with Staball hd. I had better luck with the hornady 190 cx and Staball hd. I’m just over .5 with that combo. 3090 average from a 24” barrel.
