Thread: Double grouping .... likely causes ?

A couple of pics - before and after fixing the mag box binding issue. Confirmed my diagnosis of the cause for double grouping.
This one before - a few different loads & pills all showing 2 shots in reasonable proximity (~1 moa) but the third flyer out by 2 -3in.


This one after (remember these are not proven loads in this set up, still very much starting load dev.) Chose two that looked promising even with binding max box issue and ran them again with max box fixed.

First group (at bottom) of 4 - the first shot is cold/clean bbl, next 3 show some promise just under 1 moa.
2nd grp, different pill/load looking better at ~ 0.75moa.

So now I can get on to the load dev. Beware of binding mag box !!! Kind a rookie mistake but hard to spot in this rifle.
