I have a old Remington 700 chambered I'm 280 I'm looking at rebarreling the rifle and was wondering what my best option would be trying to stick with the 7mm bore since I have tons of bullets should I stick with the 280 or maybe Ackley punch it main goal would be to drive 162-168gr projectiles at around 2950 FPS barrel will be 26" and muzzle break already have a 28 nos in the works so trying to stick with something that would work on the standard bolt face since I already have something to cover the higher end
 
280 Ackley is probably your best option. Nothing else on a standard bolt face will give you that combination of performance and availability of components/dies. This cartridge is very efficient and can be loaded down to 7mm-08 velocities quite easily for target practice.
 
Seems logical since I already have 200+ pieces of brass for the 280 I could fire form if I wanted but headstamped brass is available and cheap as well as reloading dies I was just seeing if their was anything else beside the Ackley version I was looking hard at the 7ss but was hasitant on the price for dies
 
I'll look on here and your site and read on seem like u have put a lot of work into your designs Rich

.280 Sherman... Gives you legit 7mm RemMag performance from the standard bolt face.

I'm building one as we speak! Just need my stock to get here, hopefully this week, so I can take it all to my smith and have him order the reamer from Rich.

Let me know if I can help. Call if you want.
This is no joke! I've probably worn out my welcome with all of the questions I've asked so far over the last couple of weeks. Between Rich and Steve I will have received some of the best customer support in the world on this build and load development. :)
 
It's not shot out just wanted a longer barrel really I guess and alittle more performance it's a topic I been going back and forth on since I already load for the .280 and wouldn't have to get anything new or fire form
 
Hard not to like the 280AI and or the 280 Sherman, if you want to be able to grab a box of ammo off the the shelf go 280 AI and if that doesn't matter than you can go either Ackley or Sherman.

I have built 6 280AI and have 2 more on the go but will probably do a 280 Sherman on one of them if I can get dies and head stamped brass without issue
