What's UR approximate vel.?



I chronographed the loads the same day I shot the groups.
Tikka gave 2820 fps, Ruger was 2875 fps.

I thought it was strange...............same load, same day, 55 fps difference. Admittedly, the ruger was a few years old with a couple hundred bullets down the barrel, the Tikka was new with less than 20 rounds through it.

Still got the Tikka, traded the Ruger for a 7x57 #1 International

I used WW brass and primers. C.O.A.L was 3.340"


Sniper you might find those velocity spreads tighten up if you increased the charges a grain or two. Based on your velocity you seem to have a bit of room.

Not uncommon to see a 270 behave that way when you're a couple hundred fps below a normal "max". Then again it shoots fine so...I'm just explaining away your velocity spreads.....please continue. smile



The 280 Remington is overbore.

The 7 Rem Mag is over bore.
