Roskoe. Several years back I had the first chronograph in the community. A friend ask me if I would chronograph some loads for him on A weekend. I said I would meet him at the range. When I got their he handed me 20 rounds of 416 Rem Mag ammo that he had reloaded with several different charges. He said he was afraid he might hit my chronograph so would I shoot them for him. I shot 18 of them but I could not pull the trigger on the 19th one. REALLY, No matter how hard I tried, I could not pull that trigger again. Never saw anything like it before or since. It was a Dakota Rifle which weighted next to nothing even with the 2X Luepold scope. My collar bone and shoulder hurt for a month and really has never been the same since.
I just set down now and reloaded the rounds I shot this afternoon I reloaded the 140 NBT with 40.5 Gr of RE-15. I hope toward the end of deer season that I will get to try it out. Yes that should be a very good velocity for the 140 BT.
Typical 700 Rem.
