[QUOTE="djm670, post: 858917, member: 36341"] Lets look at production ammunition performance figures (same powder and barrel lengths) - most from Hornaday, the .280 AI from Nosler and take comparable bullet weights (most sst's). Remember this is only for comparison purposes Remember initially the idea was to shot SC deer at 200 yards and gongs out to 500/600 yards. HighBoard has a .300WM for gongs at longer distance. He wasn't building a LR or ELR rifle. 7-08 139 gr --- 2950 f/s .270 140 gr --- 3090 f/s .280 139 gr --- 3090 f/s .280 AI 140 gr --- 3160/3190 f/s .280 AI 150 gr --- 3060 7 RM 140 gr --- 3240 7 RM 154 gr --- 3100 .30-06 150 gr --- 3080 .300WM 150 gr --- 3400 .300WM 180 gr --- 3130 And one can get production ammo for all of them if necessary, not that was one of the initial goals but when used for hunting is not a bad scenario... admittedly you probably won't find Nosler .280 AI at your local walmart. He has a .270, 7 RM, .30-06, .300 WM; He has a .284 Shilen match SS #5 barrel and would like to build a new rifle. The possibilities are: 7-.08, .280 remington, .280 Ackley Improved, .284 winchester, 7 WSM (very close to the same performance as the 7RM), 7 RUM. But he was looking for something to fill the nitch between the .270 and the 7RM. It is kind of looking like the only one that really qualifies is the .280 AI unless he was to go for slightly less performance with good acuracy such as the 7-.08. But the .280 AI does sound a lot sexier and has inherent accuracy and is purportedly easy to tune and you can buy production brass and or ammunition. What's not to like? [/QUOTE]
