Aarrrrggghhh don't remind me, I get to sit at my reloading bench in 3weeks.... 6months away and using factory.

Doesnt sound too far off the mark to me,I used to use federal 150gr the box said 2820 from memory and it actually shot 2760fps from a Factory Sako.
Sight in bang on @200-220m and live happilly ever after from 0-300y

This is a 150gr interlock in a High pressure system at sea level. 10 degree look angle up.
220y zero

Gone to using factory hornady American whitetail 308 150gr (what I had lying round, someone else using rifle) sighted in with new scope and stock last night at 100m, 1.5inch groupings... It will do, could have done better on my part. Went out to 350 yards and drop was around 9.5-10.

This morning playing wih Strelock I can't get it to behave, box says muzzle velocity 2820fps and a bc of. 338 (online) Strelock puts his at 5.75MOA for 350... Help?!

350m is about the limit of my shooting ability anyway but just be nice to work it all out.

Rifles a t3 with full length barrel and a Dpt on the end running a Vx1 4-12*40

@223nut I've tried your figures in my strelok+ and was getting the same 5.7moa drop at 350 and been head scratching thought you might have left some elevation on in strelok (been there done that)
Still couldn't replicate your actual results of 9.5 to 10 at 350yards. checked out the drop chart on the ammo box they have an 8.5 inch drop at 300yds off a 200 yard zero.
So if you are working off a 100m zero (109 yards) you are going to need a muzzle velocity of approx 3660 fps to achieve your actual drop of 9.5 - 10 inches at 350 (Hornady aren't that good)
When you wrote a 1.5 group at 100m was that 1.5 high? if so that means your actual zero is at approx 200yds but you should get a drop of 14inches at 350 yds,
You need to check all your strelok inputs
is it yards or is it metres
what is you zero setting (100 or 200)
check elevation is zero.
check temp setting under cartridge I think Hornady speed results are done for a 24inch barrel at 20 deg C
check if there is a vertical offset on instead of zero
check weather settings to be close to actual.
Check scope height setting (I've used 2.0 inches -knowing the actual would help)

Finally my experience with DPT cans (love them) is all my weapons have printed high with can on. Did you zero with Can off by any chance?

Might need to start another thread as we've highjacked @savageshooter s thread sorry mate
