Going to single load

COL (cartridge overall length) for my Sako is 2.470 inches at a 5 thou jump

Better than a T3

G1 bc of .485

G7 bc of .244

Velocity will be interesting in a Sako with its long throat and spacious magazine

They are about the only pill I couldn't get to shoot in my Tikka 1.8 twist

I initially had them shoot great in my 1:8 tikka @2920fps. But that was in hot weather and only one batch of pills which measured 0.020" shorter than the next batch lot I got. It was erratic as after the temperatures cooled off.
The 80gr are too long to stabilise in 1:8twist at that speed or less. If you change temp and barometric pressure in your ballistic app you can see the stability calc go up and down accordingly.
I ground 80% of the red tips off some as a test and they shot good again but their BC was degraded down to about G1 0.290!

No trouble for me stabilizing in 1:8 at 2786fps.

Is your barrel a cut rifled.
I was told I hammer forged button rifle needs to be 1-7 to stabilize but a cut 1-8

Yes but I'm not sure why it would be different

Gentlemen - thoughts on a projectile for a 18" 1:9 twist? Thanks

I'm not sure either just what a guy with plenty of NRA target shooting and reloading knowledge told me.
