Red splatter Leupould VXL 6.5X20X56 Long Range Varmint Hunter Reticule
Barrel was cut with my reamer from my Bench gun so I can shoot my BR custom
ammo in a hunting weight rifle. .
I put 30 rounds thru it, cleaning 3 times.
Using the same load I shoot in my bench gun, (140 Berger VLD, RL-17, 2850 fps) I back up to 200, changed my zero to 200 shot 4 groups but not under good conditions.
Despite the wind and the makeshift rest, I never broke over MOA except for one called pull.
The next day with good conditions, and my bipod and monopod, I backed up to 400 and got serious.
Even my fouler group was only .85 MOA, dialed up my Harmonic balancer 10 clicks for each group, noting the group size. They varied from .59 to .8. Two were identical at.59 so I dialed the ballacer back 15 clicks to fall directly between those. Fired 3, 3 shot 400 yard groups. They were . 47, .501 and .502.
So with about 70 rounds down the tube, I'm shooting solid .5 MOA groups at 400 yards. My experience has been that new barrels continue to improve for about 200 to 300 rounds so I expect that when the barrel if fully broken in, it will be a consistent, .5 MOA or better performer.
Next really nice day we get, I'll take it to 800 and really see what it's made of.
