I promised I would post results of my new rifle. It started out a 111 rem mag, I found on the internet. I ordered a Mcgowen 27" 1:9 twist, full bull barrel and had a certified gun smith slap that bad boy on the 111 action. I also ordered up the Boyd's tacticool stock to replace the factory stock.

I have been reloading for 5 years now, so I decided to test the Berger 168gr Vld. I like the. IMR 4831 powder so I started with 60 gr of that. I measured the OAL of my rifle to be 3.425inches.
Here are the results;

6 shots 60 gr IMR 4831

5 shots 61 gr IMR 4831

5 shots 62 Gr IMR 4831

6 shots 63 gr IMR 4831


It's a very accurate, but here is my question... Would the heating of the barrel shrink the size of the shot groups?
