I just got my re-barreled 7 RUM back from Hart. Since I had 30 rounds of loaded ammo I was using with the original barrel I took it to the range today to burn up. The load is 85 gr. of RL25 behind a 168 gr. VLD. I shot ten, three shot groups. The groups didn't impress me, running around 1 1/4", and I figured the new barrel just didn't care for the load, or perhaps the VLD bullets. What did impress me was the last two, three shot groups, these groups were very close to being one hole groups. Does this sound odd? Any ideas? I didn't clean the barrel as frequently during the end of the session so thought perhaps it was shooting better as it fouled more but when I did the final cleaning, there was hardly any fouling. Maybe I should load a few more rounds of this particular load and see if it continues to shoot like it did during the last two groups? The barrel is free-floated in a HS stock and had the action worked over while Hart had it. Thanks ahead of time.
