The way to get there is left to right. .308 Winchester SRP brass, neck it down to 7mm-08, load it with a 7mm bullet, fire it in a 7mm-08 Ackley Improved chamber. Zero the scope to the load, and go get DOPE on it. This is for my personal rifle. I am not sending out brass with the wrong head stamp. 800 Yard Steel Range Precision Rifle Instruction Memberships and Classes Available

MV 2640 fps And here is how it shot on the second on the second powder I tried. The second powder was to see if it would still shoot tight, but if there would also be a change in velocity. MV 2750 fps! (17" barrel) I did what I do not normally do. I went with speed over precise shooting. But the fast load is still shooting phenomenal. 800 Yard Steel Range Precision Rifle Instruction Memberships and Classes Available

Also primers are a commodity right now. I’ve gave away srp while running low on LRP. It would be nice to have a balance. Anyway, this would be my reasons.

Agree that 7-08 Ackley is a mighty handsome cartridge. SRP brass lasts many firings. In fact Peterson loaded this brass to SAAMI max .308 powder charge, and a technician tried to take the brass to failure on reloads. After 38 firings, the primer pockets had only expanded .001" and were still holding primers. He had to move to another project. SRP primers have been available the last two years. Nothing else has. CCI-450 are strong enough to light the amount of powder in these cases, and have been touted at low ES. These loads have single digit ES. 800 Yard Steel Range Precision Rifle Instruction Memberships and Classes Available

The only die I own that is a neck only sizing die is 7mm-08. It is an RCBS die. Lube the neck of the .308 brass, run it through the neck die, and you get 7mm-08 brass with no donut. 800 Yard Steel Range Precision Rifle Instruction Memberships and Classes Available

CCI 400, WSR might or might not be good depending on the powder used. One to stay away from for sure Remington 6 1/2 as it was designed for the 22 Hornet. lf the saying "Liar, Liar your pants on fire" were true Mainstream news might be fun to watch

And who would have thought that the 7-08 Ackley case design applied to the 307 Win brass for a semi-rimmed cartridge results in a: 7mm JDJ #2 aka 7mm Super Bower or 7x307 AI http://www.retro.co.za/gundex/articles/Ultimate%20(Thompson%20Contender)%20pistol%20accuracy.pdf my latest project: [b][/b] Think twice, shoot once.

I would not expect much difference unless you are running higher pressures in one over the other. Think the AI will have a little more case capacity so in theory at the same pressures a little more velocity. lf the saying "Liar, Liar your pants on fire" were true Mainstream news might be fun to watch
