I get they are longer but in comparison the Berger 140 isn’t much longer at all when compared to a 124 hammer. With the 140 Berger Iv loaded way over 40 grains.
I guess I was just curious as to the varget recommendations when in theory H4350 should produce some more speed.
Dosnt help Iv been looking for varget forever.
I guess I’ll have to grab 15 to do some measurements with
H4350 is slower burning then varget and therefore requires more powder. With the longer lighter hammer bullets you run out of case capacity.
For example here are some quickload runs. Notice the Fill %. In my experience I usually end up in the "do not load" areas, but you can still only compress so much powder in a case.
