Reloading ? 280 Rem
I have an Encore in a 280 Rem. My first set of handloads were in Rem brass, 58gr of R22, seated to 3.247. They shot well and averaged .6-.8" 5 shot groups. That brass did not last well and i got some norma brass and tried the same load. Groups opened to about 2". Then I seated the bullet out to 3.355" and groups came down to 1"
My theory is my gun likes higher pressure produced by Rems thick brass? Is that common and could I shrink my groups more by adding the max 59.5gr? How many FPS would 1.5 extra grains produce in a 26" barrel?
Thanks for any input,
