[QUOTE="Ridgerunner665, post: 1105928, member: 12660"] On the mention of the 280 Remington...if its in a modern bolt action, you can run it up to 65,000 psi just as you can a 270 Winchester... With the right powders, a standard 280 Remington with a 24" barrel can safely run a 168 grain bullet a little over 2,900 fps...and a 160 grain bullet up to ALMOST 3,000 fps (about 2,985 or so)...BUT, this does depend on the barrel...some will do this easily, others won't do it at all. The Ackley only really gets you about another 50 fps over what a fully loaded 280 Rem can do...the real benefit of the Ackley is the greatly improved brass life. With a 280 Ackley, you can get a little better than factory 7mm Rem Mag ballistics without destroying the brass on the first firing. Running a 280 Rem at 63-65,000 psi can be safely done in a good bolt action, and that'll get you within 30-50 fps or so of anything an Ackley can do...but brass won't last long at those pressures. All that said...the 280 Ackley loads I fired above (61 grains RL 26, 160 AB) are leaning on the brass pretty doggone hard too (63,000 psi)...but its 94 degrees out there...most of my shooting will be during the fall and winter, and that load will drop down around 58,500 psi in the cooler temps....all I was doing here was finding the MAX safe load that was good for any time of the year, if not for that...I wouldn't be shooting when its 94 degrees. Coincidentally...in the cooler temps...the load should drop right into node 5. [/QUOTE]
