[QUOTE="ptpyron, post: 558191, member: 30806"] I have recently had my Remington XHR 7mm RUM chamber shortened to accomodate loading Berger VLD's. I had to have this done due to the factory chambering left my bullets a whopping .467 from the lans and grooves. Dennis Olsen of Plains Montana did the work and explained this left little to no room for error on my loads. My question is by shortening the chamber and allowing my bullets to rest a mere 0.0010 off the lans and grooves, how much increase in pressure will I have? If I load with Retumbo powder @ 84 grains for the 168 vld's what would this be compared to the max saami load? Rifle info: Remington XHR 7mm RUM barrel removed and shortened .467 from the chamber end shooting Berger 168 vld's with Hogdon Retumbo powder COAL of 3.668 Hope this makes sense.... [/QUOTE]
