    Kraky. Thats wild about Retumbo! Were you really pushing it? I have found it to be very mild mannered in all my overbores. I'll have to watch it.

    In all honesty I was pushing pretty hard. I was doing 3250 with 200 ab's out of my Sako with a 26" barrel. It was toward the end of the day and I probably had 30-40 rounds down the tube and had been bouncing between several bullets and powders. I had been letting the gun cool. I guess I shouldn't blame the retumbo....it was just the powder that was in the case when it happened. From here on out I take the boresnake to the range and clean about every every 10 shots or when I switch powder. (I know, not as good as a real cleaning)
    Here's another retumbo story in my savage 300 win mag. Initial data by Hodgdon said you could go 84 grains with a 200 grainer. They since have backed that claim down. But I had gotten up to 83.5 with a 200 ab doing 2930 and shooting decent...no pressure. OK, so now I want to sub in a 180 tsx at 84 grains. Surely (my pee brain says) the slipperier and lighter tsx should not be a problem with 200 data. I put 3 shells down range before stopping when the chrono read right at 3250 for each.....terrible accuracy....and all primer pockets shot. The rest were disassembled.

    Crazy! I would have figured kile you that 84 grains would be ok. That is great velocity for the 300 with the 200ab. I have never tried retumbo in the 300. I use it in 30-378, 30 warbird and the 7mm ultramag.
