300 whisper super-sonic load range results

[kurtz]

went to the range today to try a few super sonic loads: 24" 1:11 CZ527

19gr 4895 125gr nosler BT 1.605" at ogive = 1505 fps
19gr 1680 125gr nosler BT 1.605" at ogive = 2125 fps
19gr H110 125gr nosler BT 1.605" at ogive = 2375 fps
19gr lil'gun 125gr nosler BT 1.605" at ogive = 2470 fps

20gr 1680 125gr nosler BT 1.605" at ogive = 2160 fps
20gr H110 125gr nosler BT 1.605" at ogive = 2450 fps
20gr lil'gun 125gr nosler BT 1.605" at ogive = 2565 fps

found that loads of H110 that would shoot over 2500 fps on 90 degree days were over 100 fps slower on a 70 degree day....1680 loads we around 75 fps slower.....

this was my first experience with lil'gun, wanted to wait til fall/winter to try....very tight deviation and groups in the 20gr loads, as little as 6 fps in three round strings......the deviation was greater in the lower charge loads, around 35 fps.....velocity was good and pressure signs were OK....shot (5) 3 round clovers at 100 yds.....looks like it will be my go to powder for the winter time..........
