[QUOTE="Alucard, post: 65859, member: 4064"] Srhaggerty I would stay away from the IMR powders in the .220 swift. While they are great powders and do perform very well, they have very high burn temperatures. I used to use IMR 4831 with a charge of 42.2 grains. After 2-3 shots the barrel would be VERY hot - I have heard that this is the case with IMR 4064 as well. I have shot a Swift for years and tried just about everything out there. I personally use Alliant Reloader 15. It is a very good powder with a slightly low burn tremperature. I use Speer TNT 50 gr bullets with a charge of 39.5 grains of Reloader 15. I had chronoed them at about 3850 fps. The bullets hold together and I have group averaging 5 shot 1/4" groups at 100 yards. My Cart overall length is 2.770" I have to single shot the rounds, but hey, that is what varmint shooting is all about. [img]/ubbthreads/images/graemlins/laugh.gif[/img] Another great load for me was 38.0 grains of Reloader 15 with a 55 gr Nosler Ballistic tip. About 3/8" 5 shot groups at 100 yards. I have personally shot this load out to 800 yards ( won't even fleck paint anymore at that range [img]/ubbthreads/images/graemlins/tongue.gif[/img] ) Good luck with that swift! You will love the performance and the accuracy. [/QUOTE]
