Re: Yet another question( Neck Sizing)
Actually, the best way to get Swift performance is with a 22-250 AI.
Here is why and its advantages over the Swift and the standard 22-250.
-nearly zero case stretching even with full tilt loads when chambered correctly.
-Every bit the velocity of the best 220 load. In fact in same length barrels, the 22-250 AI will actually have a slight velocity edge.
-Ability to fire factory 22-250 ammo and in the rifles I have chambered for customers, will get 1/2 moa groups with these loads on average.
-More efficent case design then the Swift, feed better(no damn rim), better powder ignition characteristics and better quality brass.
SO in my opinion, I love the performance of the Swift, but it is far better out of a 22-250 AI then the swift itself.
For real serious 22 caliber rounds, I prefer the 22-6mm AI with a 55 gr pill loaded to 4200 fps out of a 26" barrel. This is easy to do with 56.0 gr or RL-22 and pressure will run about what a 22-250 will with a 50 gr pill at 3800 fps.
Just one smiths opinion.
