Quick load

salmonchaser · Nov 18, 2020

Currently have quite a bit of RL17;15 and H4350 on hand. Could somebody run a quick load for the 7x57 Nosler 150 AccuBond @ 3.15coal.
Thanks

Here's something to compare the QL RL17 data to:

Brass Winchester, bullet 150 gr. Nosler Partition primer WLR. The rifle a Winchester M70 Feather weight with 22" barrel.

1. 47.0 gr. 2710 FPS ES26 FPS group 1.0" Almost a perfect triangle.

2. 47.5 gr. 2751 FPS ES19 FPS group 0.8"

3. 48.0 gr. 2793 FPS ES30 FPS group 1.25" Two touching and one flyer. Was it me or the load? I don't know. However in loads 2 and 3, two close togather with the flyer to the left and slightly higher. Note how close the velocity was compared to the QL data.

Hope this helps.

QL has been pretty good to me for the most part with its projections based off general data... Only been a few cases where it hasn't, and that's probably just because some not so good data went in. Pretty invaluable program for the serious handloader.
