ok finally got to shoot it.
today was the third attempt.
i think i know a bit about loading but this gun produced significantly more velocity than expected.
first trip, starting load gave a stiff lift and 200fps more than expected.
second trip...three grains lower than the first starting load, gave what i had expected on the top load for the day...so back to the loading bench.
today, light wind...cold 36 degrees 64% humidity and all went well.
68.5 gave 2911 an es of 10, aprox .45 with only .06 vertical, ...5 shot data, shot as 2 fouling and a 3 shot group
69.5 was 2956 an es of 12, aprox 0.62 with .27 vertical .. 3 shots
70.5 was 2986 an es of 12, ....well i had to reset the bag and the group sucked..2 at 0.4 and the 3rd 1.5 away...vert on the 2 was .35......bolt was firm on the last three but not hard.
so now i have all of 17 rounds thru it.....
ohh and these were all at 200 yds.....
the backer sucked and the target ripped alot thus the "aprox" numbers.
will do some more work...this was all with 208 amax's and h4831, rws brass and russian large rifle mag primers.
