Proof Prefit Barrels -- Opinions?

[rijndael]

I have to say, I'm loving my Proof prefits. I'm currently using 2 of them.

I just had to make it a 6 shot 'group'. Sigh.

I know this is an old thread but just started with a Proof/Origin in .223 Remington that has a lot of promise. First groups just to test seating depth at 100 yards, only a handful of foulers with no break in. 4 out of 5 groups under 1/2 MOA, with 2 being ~3/8 MOA. Berger 80 VLD’s and Lapua brass.

OP Here .... I now have a pile of them on the shelf and have no regrets.

<= 1/2 MOA

I bet I could beat that. What action?

 

[rijndael]

I'm using Defiance actions.

I'm using Defiance actions.

What caliber did you go with?

My Proofs are 6GT and 6.5CM.
