I have purchased my first .338 Lapua and have a question about the ammunition. I purchased some Sellor & Bellot, the box states 1:10 twist. Can I use this in my Ruger RPR .338 Lapua that has a 1:9.375 RH twist?
 
It won't hurt anything, usually stated twist rate is a minimum recommendation. There are risk of deforming projectiles if they're over twisted but your barrel is not too much faster than ten.
