This was in a 308 using 225gr cast with gas check, 43gr of IMR 8133.
CCI LRM. Average 1888, SD - 15
Win LRM Average 2046 - SD - 55 +158 fps
Brass was the same for all loads and freshly annealed.
Not sure what’s going on with the SD. I shot 6 rounds of the CCI, 5 of Win.
A buddy of mine bought his reloading gear out of cold storage and set it up in my heated woodshop. He had 50 Win LRM primers in his “stuff”!
