dRb Posted May 13, 2014 Report Share Posted May 13, 2014 Does anyone happen to be, or have previously used, the above combination? I started looking at working up a load for it yesterday, taking a guideline from here: http://accurateshooter.net/Blog/sierra22-250loads.pdf Using the 40grn Blitzking as a vaugly comparible projectile. Unfortunately I think the light was all at too shallow an angle for the chrony to work (error 1 or 2, or just not noticing that I'd fired!), but I was getting nothing at all pressure sign wise at 39.8grn of powder...not sure I can fit much more in the case!? Others experience would be good to hear I'll try again with the chrony today. Link to comment Share on other sites More sharing options...
dRb Posted May 13, 2014 Author Report Share Posted May 13, 2014 Swamp Donkey's suggestion of putting marker pen in the bullet worked to get a reading from the chrony! Thought my leg was being pulled... 4062fps, so not as hot as I thought it'd be. Link to comment Share on other sites More sharing options...
22cf Posted May 13, 2014 Report Share Posted May 13, 2014 I have a mate using Vit 135 with 40grain SBK and is getting 100yd 1 hole 5 shot groups, he is literally putting them through the same hole, we were out lamping with it earlier this week and they were performing incredibly well, dropping foxes on the spot with no signs of exit. Very Impressive. Link to comment Share on other sites More sharing options...

dRb Posted May 21, 2014 Author Report Share Posted May 21, 2014 drb , have you pushed them any faster yet? interested to hear fps ? Not had any spare time recently due to a big trade show with work! I'll be taking my 22-250 in tomorrow though, and will work up to a full case (assuming no pressure issues obviously), and see what it gives.

Apologies for being butting in, but could you explain the marker pen thing on the bullet to me as I have a chrony and get the ocassional "Error" screen?

That's a lot of powder for that speed, barrel burner I'm getting 3960 fps out my 223 ackley with a 40gr nozler and using over 10 grains less powder Gaz Link to comment Share on other sites More sharing options...
pork chop Posted May 22, 2014 Report Share Posted May 22, 2014 i thought the same gaz,i can get in the high 3900's using 32 gr of v135 in my 22 br and that's with a 50 gr vmax.may be a change of powder would help with speeds Link to comment Share on other sites More sharing options...

Marky610 Posted May 22, 2014 Report Share Posted May 22, 2014 Anybody? I'm guessing it will make the bullet show more contrast so the chrono picks it up better Link to comment Share on other sites More sharing options...
