The combination I tried: 200 gr LRX + H1000 definitely a no go. With the length of those bullets, I couldn’t seat at -.050” and going to -.040 didn’t help much . Just won’t work for me. So I’m going to give H4350 a try. Plenty of room to seat deep, and providing no high pressure signs may be able to stretch the max load a bit. With the smaller bearing surface of the TSX, I’ve done this with my .308 Win
and 325 WSM with good success safely.
