Range Report 6.5x47 chronographed

[birddog28]

I got a chance to actually chrono my rifle. I had been backing come ups into JBM for a while and thought it was running around 2850. Found out I am at a lot slower node than that.

123 Scenar average 2750
120 A-Max average 2795

It was suprising. Not going to change anything, it shoots great and I have been running it this way for a year and a half and this gun has all kins of blood on it.


Its funny that JBM over estimates the speed with G1 BC's. Any body else had this experience?

What's your load, and barrel length? G7 should be more accurate that the G1.

35g RL 15. 26" Broughton. I know Litz has that info on G7 but I have not bought a copy yet.

The re-sizer die I am using is a little out of spec. Its a forster bench rest and it does not bump the shoulder back enough.That causes some pressue so I can run the hotter on virgin brass. I just need to send the die to forster and have them machine it a little.

I may be able to give you a little insight into what your rifle can do, even though you don't want to change your load.
I also run a 26" Broughton and RE-15 and 123 Scenars. I use 37.5 and get 2940 fps and is easily under 1/2 MOA.

If you have found a accuracy node at 2750 it will only make your barrel last that much longer.
