I have the MOA ….. I was shooting out to 500 yrds today and I found myself using 24 to 28 power.

[onbadmofo]

I have settled on the Sightron 8-32×56 and Seekins rings…. Ordered Today

[onbadmofo]

At 23.8 I started getting a little sticky bolt lift that is why I backed it off to 23.6 and all is fine there. Groups are .500 or better when I am doing my job behind the bolt.

Dog,

I ran 2 loads of .223 68gr BTHP, 23.6gr & 23.8gr Benchmark Powder 7 shots each to find the SD.

    23.6gr avg FPS 2852 SD 10.12
    23.8gr avg FPS 2843 SD 18.17

You were correct the lower SD grouped better, I was amazed how .2gr made a difference.

[onbadmofo]

Hey Dog,

What model of Vortex do you have?

[onbadmofo]

Or a Vortex 6-24 x50.

What would you consider a good SD to work for?

[onbadmofo]

I don't mean to sound dumb…. what is SD?

How much recoil do you feel was reduced with the Vais brake?  Did it come with the threads to match your CTR?

[onbadmofo]

YES….. I WILL TAKE ONE

[onbadmofo]

The roll pin was falling out of the mag release lever, the mag was staying in place just fine. I sent it back and they staked each side and it is fixed.

UGLY  😮

I have a Primary Arms 4×14 scope it is very clear, I am also working on some Hornady 150gr FMJBT I have moved the COAL from 2.700 to 2.800 and trying Varget and IMR 4064 (not mix together) and so far 45gr is close.
I have a standard brake on mine…..but I have a JP Recoil Eliminator sitting in the drawer I will be trying the only bad thing about is it is soooo ugly.

[onbadmofo]

That is outstanding @ 200 yrds, thanks for you help I feel like I am getting closer…….. I loaded some up today and 44.0 to 45.5 and it was coming together at the 45.5gr best was .800 group, so I am going to load 45.2,45.5,45.8,46.2,46.6 and see how it goes. I am using my FGMM .308 Brass for testing and when I get the where I think it is the best I will change to my Nato Brass and see if how it changes if any.

I was able to gain 500PFS and still keep under 1in.

Best Today @ 100 .800
Fed GMM Brass
Fed 210M Primer
