[QUOTE="Michael Eichele, post: 338665, member: 1007"] I found that with my RUM's (300) that after the throats were degraded, which happened fairly quickly, that the subsequent friction caused higher pressures than when the bore was fresh. Once this happened, I was stuck shooting 3200 FPS with the 180 grain variety to keep the bolt from sticking where as I was getting 3350-3400 when they were new. I had to back off at 65 rounds with one and somewhere around 100 rounds with the other. For the end result to be 3200 FPS, I may as well have just got a 300 WSM, WM or WBY mag and burned less powder and enjoyed more of my money on other shooting supplies instead of new barrels. Albiet I did get 1100 rounds out of one with good accuracy. [/QUOTE]
