BC30 what action is that, a low wall? Can't tell from that angle.
Tejano;
Good evening to you sir, I hope the day treated you well and it's not too, too hot in your locale tonight.
The action is a Browning B78 built by Miroku I want to say. It was an octagon barreled .22-.250 too by the way.
We never were able to ascertain what happened - as in what the cause of the over pressure load was, but my goodness it let go in spectacular fashion.
At the same time in my reloading/shooting life, a good buddy had a B78 in .25-06 and we did our level best to make that 26" octagon barrel into a .257 Weatherby using the original batches of AA3100 that came up here across the medicine line.
Flat primers and spectacular chronograph numbers were all we got - well it did punch volley ball sized exit holes in the local coyotes too with the 75gr HP Hornady we were using, but otherwise we came out unscathed.
Hopefully that answers your query sir, but if not please ask and I'll do my best to respond.
All the best to you as we head into the hot portion of the year.
Dwayne
