Re: Shooting 100 & 200 Yards
Desert Frog, I shot another 6 5-shot groups today at 215 yds and got the following measurements CTC: 2 1/8", 6", 2 11/16", 1 3/4", 3 1/8", 2 1/2". Converting to MOA, that gives me .94, 2.66, 1.19, .78, 1.38, 1.11. That gives me an average today of 1.34 MOA. These were all with a bipod rear sandbag. On the 6", it was sort of a guess because the bullet hole dropped down to the next target. Every once in a while, with this lot of ammo, I get an undercharge, and that was it.
I have some other targets from today that I can post later on. I have a few 100 yard 5 X 5's I can post. I will need to run those in On Target. The 200 yarders I can measure by hand no problem. For tighter groups, I am not very handy with calipers or a tape measure for that matter.
Some ammo that I had all but written off months ago was shooting lights out today at 100 yards. I am interested in seeing if the results replicate some ammo that I had a while back that gave me a 5 X 5 at around .77 MOA and one at around .85 MOA!
I don't think my results are from being a great shooter... I think I lucked into a great gun. I bought it off of nesikabay on the Hide who bought it off of 95LTZ on the Hide who bought it off of Lige Harris, who had it custom made by Gene Davis. I don't know why anyone would ever sell this rifle... and to have it be sold twice! I am dubbing it 40x-caliber, because it has some magical properties.
Also, I think that the Eley ammo helps. I obsess about finding the right lot and the Eley bullet with the dimple nose gives it a slightly better BC than the typical round nose ammo on the market. If you look at the ammo in the winner's circle for rimfire, both benchrest and position shooting, it is dominated by Eley. And it is not because Eley is so great, but rather because they keep good track of their production lots. They test each lot for velocity out of standardized rifles and they also demarcate which machine the ammo was made on. My gun does really well with 1059 - 1063 fps ammo made on machine #5, for instance. This allows me to test only ammo that is likely to be good for my gun. There are a lot of little tricks to rimfire... and also a lot of superstition. Like it doesn't make sense to me why one machine would be better than another, but after extensive testing, it turns out that it is true (at least based on my analysis).
