[QUOTE="436, post: 2412324, member: 16609"] I've shot a few Deer with the .220 Swift and found that the 55gr bullet worked quite well, and was about the top of the weight limit for my barrel twist. I also shoot a .224 Weatherby Mag in a 1-14' twist. The .224 WM 50gr bullet is where my accuracy is best and the twist and weight limit for it. So going through P.O Ackley manual, volume I page 283 .220 Swift standard one... he finds no decent return in performance by going to a 40 degree improved cartridge, his words, not mine, which he stated again in P.O Ackley manual, volume I, on page 285 .220 Swift Improved (AI) showing it highest load with a 50gr bullet being 4100 fps in the (AI) He showed the highest load for the standard .220 Swift with a 50gr bullet as 4050 fps... essentially no real gain. One other fact that is very interesting about the .220 Swift is P.O's work on penetration, pitting the .220 Swift, .270 Win 100gr, and .30-06 Springfield G.I AP against each other, again in P.O Ackley manual, volume I page 83 P.O's first book/manual P.O Ackley Handbook for shooters and reloaders page 65 #15 says he thinks it's extremely deadly on Deer, well... all I can talk about is the couple I've killed with one, and it anchored them with the first round, now... to be far these were Whitetails and the longest shot as I recall was just over 300 yards with a 55gr bullets. As for P.O Ackley manuals, volume II... is just volume I... 2.0 a few added cartridges in volume II not many,... same, same a bit more on the .17 cal's in volume II Good luck... Cheers [/QUOTE]
