how does the 7x57 ackley beat the 280 ackley loaded to the same pressure?Fizzle...7x57 Ackley Improved (have the companion 257 AI as well-love 'em both and excellent shooters!) Montana action, custom SS bbl, Timney trigger, bedded, silver's pad. Phenomenal! Not far behind a 7mm mag and beats the 280 AI. Best efficiency gains by improving the 757 case. Shots are the first two different test loads per P.O. Ackley's recommendations. What I want, first and foremost are ACCURATE rifles. The fact that they may be pretty are icing on the cake, with lotsa candles that fizzle!
and don't say more efficient, because then a 7/08 improved would be better again, and a 7mm/250/3000 would even be better again.
