Many moons ago, I had an E A Brown single shot built in 6.5 BRM for my then infant son. He turns 21 in a month! It is a bit different in that it has a 21 inch light barrel with a 12.5 inch lop. With the short barrel, it will easly do 2300 fps with 140 gr bullets. 120gr BT are accurate and do 2500 from my short barrel. My son killed his first buck with a 100gr partition at 2500fps - a really lite load. I have loaded them to 2750 in this rifle. Bet you could do 100 - 150 fps faster with a 24 - 26 inch barrel and still have a handy single shot.
