Thread: 270 powder loads?

I use 2213sc with the same 150gn SST projectile in my Sako 75 .270
I dialed down the speed from atomic to save the brass and barrel.
No need to push the SSTs too fast.
I use Fed Match primers and annealed neck sized RP brass for average 0.4 MOA, best of 0.28 MOA.

Hi dogmatix
Have you read Nathan fosters info as Kurlyman suggests, do you anneal the projectile? If not how do you find the sst at "not to fast" speeds?
Is not to fast below 2800fps?

Cheers

I used to use two 270's one was a lightweight and was used as a bush gun. In it I ran 130 grn hornady SP with IMR 4350 behind it ( similarish to h4350 / ar2209 )
The theory being for a short barrel to use a faster powder. I was getting 2850 fps
Seated short to just behind the cannelure
I also ran a 24 inch barreled XTR best load developed was 140 grn SSt's behind AR2213 sc for a MV of 2910 fps I had both these old 1980's rifles shooting sub moa.
Seated out real long with about a 10 thou jump.
But each one shot a different load and powder, so what I am getting to is that you need to do load development to suit your individual circumstances.
I tried 150's in both these guns but couldnt get them to group / shoot any where near as good as the others I mentioned

Thanks John,

Yes I intend to work up a load eventually. Need to get hold of a chrony and the rifle to measure up. Looks like I'll be starting with 2213sc
Thanks heaps for your input
Cheers
