I built a 6.5 prc and 6.5 saum gap 4s( shorter freebore). I prefer the 6.5 saum. The 6.5 SS would be just as good and likely a slight performance edge over my saum. I'm at aprx 3150fps with a 147 &n570 in the saum. The ss would likely do that with less pressure. The 6.5 prc is a good avenue to take if you see yourself having to rely on factory ammo ( if it ever becomes available again).So this could end up being a year or two out but I'm wanting to put together another custom build and this time in a smaller cartridge that would get shot a lot for many different things.
I'm leaning toward one of the higher performance 6.5 such as SAUM, PRC or Sherman Short. What I have in mind is to run a light load with a 140ish grain pill at 2900 fps or so for most shooting and hunting but I want the ability to run the 156 EOL up around 2950 fps if the hunt warrants it. I would build with a 26" barrel so I'm not pushing harder for velocity.
Some key points to consider.
Will any of these cartridges need a medium or long action to run the 156 EOL seated out where it belongs?
What is the case capacity of each cartridge?
Which cartridge will have the best feeding?
How is the the Sherman stamped brass (I believe ADG)?
I am partial right now to the Sherman Short Tactical but I don't know if it will achieve my velocity goals or what all else is out there to ponder?
Thanks for your help and experience guy's
