I want to start reloading for my model 10P-SR in 308 with an 18 inch heavy barrel.
I have read online when using Lapua brass you must back off the powder a bit due
to a decreased inside volume. Are there any online reloading references exclusive to Lapua
brass and powders? I want to use Varget and SMK 165 bullets. Can someone shed light on this
or suggest a starting point. Thank you in advance.
