[QUOTE="Fiftydriver, post: 78527, member: 10"] Lafe, First off welcome to LRH!! I am suprised you are dusting bullets in the 1-10 at 3770 fps. Can you tell us if you got any bullets on paper or has it been dusting them from shot one? Did the bullets even land on paper at lower velocities and if so at what velocity did they start letting go? With the case capacity as large as the WSSM has I feel the 1-10 twist is just about right as it has plenty of HP to drive the heavier 22 cal bullets. To be honest, drop the lightweight bullets and jump up to the 69 gr class with this big gun and the 1-10 twist. You will loose a bit in dramatic expansion but you will gain significantly in ballistic performance. Also, the heavier bullets will generally help this round perform better. With 50-55 gr bullets this round will do very little more then the Swift will but if you move up to the larger bullets you will gain more velocity advantage with this large case capacity. I do not think you will get the 80 gr pills to stabilize in the 1-10 but it may be worth a try. I would get some 80 gr Sierra MKs in or ask someone if they could spare a dozen or so to test before you buy any. If you could get the 80 gr bullets to stabilize, you would be in a relm of ballistics head and shoulders above the traditional varmint bullet weights. I would seat the bullets 0.020" off the lands to start load development until you figure out the rifles personality. One last thing, are your bullets really hard to seat in the tight necks of the cases? are you getting alot of jacket shaved off the base of the bullet when its seated? If so this may be increasing the problem with the bullets letting loose. One sure way to solve this is to switch to a Ballistic Tip bullet as they will handle anything you can drive them to. I have hit 4300 fps in a 1-8 twist 22-6mm AI with the 55 gr Ballistic Tip and got 1/4 moa groups with it. May be worth a test if you are dusting bullets. Kirby Allen(50) [/QUOTE]
