Maybe the wrong place to air this, if so feel free to delete or move.
I keep seeing quite a few folks wanting heavies for LR shooting and decided to do a run or two.
My reasoning was does the speed(velocity for purists :grin: ) you give up while adding a little recoil make enough difference to shoot the heavier bullets or not?(not judging just curiosity)
So I did a couple QL calcs and took them over to the JBM calculator.
I ran a Berger 130 VLD in .264 versus the 140 VLD to 1000 yards.
Here they are. Thoughts?
