Frankenrifle shoots.... Frankenrifle scores!
And a closer look:
Top is 100m, 135gn Sierra MatchKing loaded just off rifling, 23.0gn (weighed) VV N130 (actually rounds number 14-19 through rifle - 3 @ proofhouse, 10 gash rds for shooting in, then these).
Bottom is next 5 rounds (with a full cleaning in between the 2 strings), same but 23.5gn (weighed) N130.
Top measures at approx 15mm c-c (0.54MOA), bottom 10.5mm c-c (0.375MOA).
Scope was Leopold 1.5-5x20 set at 5x power.
With original barrel & stock, this rifle would do 4MOA on a GOOD day, IF it held zero... ANd that is a BIG if...
Adding the brake made it shoot about 3-4" high, and the group with 23.5gn N130 opened out to about 1MOA. Can't really grumble, though!
So, this is the proof that there's nothing inherently wrong with 7.62x39, it's just the rifles and cavernous throats they give them. BTW, Lapua 123gn .311" spitzers loaded to mag length WILL NOT chamber in this rifle!!! I think the mil stuff does though; will have to check...
Stoaty is MUCHO chuffto, and you can all apologise for being nasty to Frankenrifle.
