I recently bought a Rem Model 7 in a 270wsm. I found a load that is awesome. 140gr Nosler Accubond 63.0gr XMR3100 Win LRM primer Win cases I shot two three shot groups a week apart. Both times the three holes could be covered with a dime. Now I want to see if I can work up a good load for Barnes 110gr TSX BT. I am not made of money so I can't just go out and buy 3 or 4 different powders.So I am thinking of RL-19, RL-17, IMR4350. What do you think? Which one would you pick? Or any other make?
