So far I have not had a problem with the 40s at 4400+ ft/sec .I have not exceeded 4500
ft/sec with the 40s but I am going to try unless I see signs of pressure or accuracy loss then
I will stop.
When I first posted on this project I received some good advice on bullets and found it
to be true.(40grain Ballistic tips have a heaver jacket that the heaver ones) and chose a
slow twist rate (1 in 15) to help the bullets hold together.
After I reach Max with the 40s I will test the 35 grain BTs to see what happens to them at
