[QUOTE="Trickymissfit, post: 697826, member: 25383"] with a standard 22-250 case necked down, I doubt it. But I still think 3550fps is doable. Have not seen in ballistic specs for a 55 grain 20 caliber bullet out of the Ruger case, but you can get 3700fps out of the 45 grain bullet(max). The problem with necking down cases is that you also loose surface area at the base of the bullet. (in this case not a lot) So it's easier to push a bullet with a little more square inches of surface area at the base. Add to this the fact that you can only burn so much powder before the bullet exits the barrel; no matter what it's length. It kind of appears that 30 grains may be just about max for this bullet. I suppose that if you had a good shot out barrel and a reamer it'd be a good experiment. gary [/QUOTE]
