[QUOTE="HoytemanPA, post: 238692, member: 286"] SquirrelNuts, I think it was the combination of the two. As I am sure that I got it just as hot, if not hotter with the H50BMG test. And I had shot similar amounts of rounds during load development using RL25, but allowed it to cool without adverse affects. Intentions of the tests were initially to find the limitations of the powder/heat effect in the expendable barrel before using the round for 1KBR in which a minimum of 12-13 rounds are sent in less than 2 minutes. And while it didn't shoot bad, the greater bag disruption and added expense of components, offset any gain that came from reduced wind deflection. So now it is a pretty blue varmint/hunting rifle that I am sure I can send the first 10 where they are supposed to go at any rate of fire. With the factory Accumark I think I would limit rounds to 5 or 6 and allow it to cool. My findings mirrored J E Customs with the Accubonds being a very good bullet for normal Weatherby freebore. But I couldn't get them to shoot in my current shorter throated chamber. Also agree H50BMG is a good powder for this cartridge, I have 6 pounds left for this barrel. Let us know how you make out.
