Thought some might find this of interest....
Rifle is a Winchester 70 Classic Stainless, 24" Lilja #3
I had been working with Retumco, with less than satisfactory results.
Switched to H1000 last weekend. Range was 100 yards, temp was around 52 degrees.
74.5gr H1000 shot into .676, no velocity reading on Chrony
75.0gr .481, @ 3031 FPS
75.5gr .673 @ 3056 FPS
I then cleaned the rifle, and re-shot all three loads twice each this weekend.
The 74.5 gr load was up first, shot greater than MOA (clean barrel?)
75.0 gr Averaged 3071 fps, first group into .516, second group had a flyer that opened the group up to 1.376.
Without the flyer all three groups are sub .5 MOA, with the lowest spread and deviation of all loads.
75.5 gr averaged 3079, .734, .693......all three groups averaged .70.
Based upon the velocity between 75.0 and 75.5, this may be top end, although there were no pressure signs.
Plan on re-shooting 75.0 and 75.5 at 200 yards next session...
