I’ve not been really satisfied with the 105 Hybrids and Varget so I’m trying the 107 SMKs and 108 Berger BT Targets using H4895
Here are my load test targets at 100 yards. To explain my notes, average FPS on left, charge weight on top, group distances from center line on right (to get comparison of vertical change between charger weights). Using the “cortina” method.
Looks like a really wide node on the bergers from 29.5 to 30.5 where the groups vertical distance doesn’t change very much. Might even be able to include 31.0
The SMKs had a more narrow window between 29.5 and 30.0
Next step: I think I’ll take the bergers with 30.5 of H4895 and do a seating test, primer test and then shoot them at 500 yards and see how they perform
