I have a 338 RUM, 28" barrel. I am loading 90gr of RL25, a 300gr SMK. COAL 3.790" my average velocity is 2836. This seems fast to me. One of my buddies is shooting his 338 RUM with 89.7gr of RL25 from the same keg of powder is getting 2710. He has 27" barrel. The difference in velocity seems very high between the two rifles given there is only 1" of barrel and 0.3gr of podwer differnce. Any ideas on why there is so much differnce would help. I am mainly concerned that I might be pushing the my rifle to hard.
