[QUOTE="CA48, post: 2004302, member: 21446"] There’s no way to know without testing it. H4350 is a double based powder with a higher burn temp than H1000. What I can tell you is after measuring throat erosion that one day of pressure testing with N570,RL26, and Retumbo, around 45 rounds total will burn up more of your throat than 200 rounds fired with H-1000 while keeping the barrel cool and only firing 2-3 rounds at a time. I think it’s safe to guess that bbl life could easily be dropped to the 400-600 round range if your firing hot loads at 3900fps and getting the barrel hot. Currently my barrel has 1,108 rounds through it. [/QUOTE]
