Thread: Pressure / barrel speeds?

half a grain should be good in 270.
one of each up from your current load.

So what is your current powder type/gns/projectile type/weight/barrel length?

Hey gibo, with the Tikka. You will notice that your bolt lift will get quite hard when the pressure rises.
Or at least that's what I find. I can struggle to open the bolt at times when finding max load. But there won't be a mark on case and primer is only slightly flattened

Am currently working up loads for a 22" barrel .270 also, on a Weatherby Ultralight action, currently at:
-150 Berger VLD: 58x2213sc@84 fed210 2900fps 3/4" average (no pressure signs)
-140 Berger VLD: 58x2213sc@84 fed210 2900fps 5/8 average (no pressure signs)
Am going to bump the 140 VLD up 2 grains in 1 grain increments to get to 3000fps, and try the 130 VLD Classic Hunter (top BC for a 130gn 270 proj) looking to get to 3100fps, probably the maximum sensible velocity for a 22" barrel, (especially in a 6lb rifle) not able to get the consistancy in accuracy and velocity I wanted from 2209, if 2213 hadn't worked so well I would have gone to 2217

Have tried a few others but the Bergers work so well I'll stop with them.
This rife is going on patrol in a few hours, hoping to find a resting place for a 150 VLD before oh dark tomorrow night!

Is it just me or is the adi manual weak?
