[QUOTE="SES50, post: 253649, member: 7753"] I have been thinking of building a light weight backpacking rifle for a while. In my mind it need to be short action and a short barrel with the smallest contour possible. I am thinking bullet weight around 140-165 grain. Which puts me around a 6.5mm-7mm diameter. I know that Kirby built an xp100 pistol that had an 18" barrel that pushed a 140 gr 6.5 in a WSM at 2900 fps. If I go with the 7mm WSM and a 20" 3 groove Pac-Nor barrel do you guys think I can get over 3000 fps? Also is there any 7mm WSM wildcats that increase the case volume to take more powder? Thanks for any info you guys have. SES50 [/QUOTE]
