. . . I'm interested in your load, have you chronographed it? jorge

I had a range session with this rifle yesterday. My old supply of IMR4895 ran out and was replaced with 16 lbs. from another lot. So I did the right thing and did a fine-tune adjustment of my pet load, using the new powder. I tried loads of 37.5 grains, 38.0 grains, and 38.5 grains.

With this new lot of powder I found that my best load is now 38.0 grains with a Fed 210 primer and the Woodleigh 215. My OAL is 3.063", which seats the base of this bullet right at the bottom of the neck.

It's a wonderful load, and my rifle loves it. My average velocity of 8 rounds yesterday clocked 2175 fps.

Here's a look at my target, with the chronograph printout:





Only seven shots are on the target. I am embarrassed to admit that as noted, my first shot out of the right barrel barely grazed one of the screens of my chronograph, causing it to fly wide of the target. It's velocity did register, though. I re-adjusted the chronograph screens!

My group measures approximately 1-5/8", and the two barrel groups indicate the barrels are shooting parallel. It's hard to see on this scan, but the three shots on the right are the right barrel group, and the four shots to the left are the left barrel group.

If you are wondering, the notation at the top of the chronograph tape, beside the load data, 3.270", has to do with my powder measure setting.

I also see, that as for these 8 shots (four from each barrel) the left barrel clocks slightly faster than the right. The right averages 2162, and the left 2189. This would have to be repeated many times to draw any conclusions.
