Ok so here goes. First and formost I'm for sure going to run this ladder again next weekend. I had 3 rifles too work on today and since the bolt action isn't needed for the rest of this deer season it was the last up to bat.
My range closes at 2pm and by the time I had both my ar grendels dialed back in and was happy with the sight in, it was already 1pm.
So I had to fire all these rounds on a hot barrel. But here goes.
6.5 staball/129 ablr results
Ladder 25 to 30.8 grains
Starline new brass
Cci450 primer
Coal of 2.315
25-1716
25.2-1735
25.4-1746
25.6-1751
25.8-1754
26-1766
26.2-1785
26.4-1821
26.6-1856
26.8-1874
27-1920
27.2-1927]
27.4-1911
27.6-1948
27.8-1976

28.2-2036
28.4-2038
28.6-2064
28.8-2070
29-2108
29.2-2117
29.4-2145
29.6-2171
29.8-2181
30-2155
30.2-2186
30.4-2200
30.6-2214
30.8-2298/spike
So there you have it gents. Had one are 2 rounds that look like they got a low charge and 30.8 was on a very hot barrel but looks like a SPIKE.
Will be interesting to see what this ladder does next weekend. I'm going to reuse the same brass for this ladder.
Also had enough time to grab some velocity data for American gunner. 10 shot average was 2520 fps.
Got too try a 5 round group from this rifle with
85 trex, 30.4 h335
120 gold dot, 26.8 varget
129 ablr, 25.5 h4895
The 3 test groups listed just above is what's in the pics.
Smallest group is the trex, next size up is 129 ablr and the biggest is the 120 gold dot.
I was rushing for time bad and pulled shots on each group. These were shot at 200 yards.
