For targets and general shooting, for a factory round, that’s decent. But for me the bullet I want to use is this 103eldx, esp as a hunting round. The quest therefore will continue. When their factory 103 comes out I want to see what it does, but something tells me I will want to roll my own. I am always happy when I can find both factory and hand loads shooting good groups... that’s a sign I’ve got a keeper barrel.
I figure I’ll find a node for the 103 around 2700-ish, which will be where I’ll be happy, 103-wise.
Part of my internal ballistics grand-theory is, a “faster” barrel is so because its internal friction is for some reason, lower... 5R, slicker insides, whatever. Generally then a given, expected powder load yields less than expected mv and pressure. But that’s the beauty, because you can tweak up the charge and the extra powder/pressure/energy sends the bullet scooting down the pipe faster.
A secondary goal today was to find if there is a barrel mfr (maybe just 1 barrel but a mfr more likely) that can handle 105s and etc at decent coals. So today also bolsters my feeling that some of the throats PP et al, got are too short n stubby, and the mfrs should fix ‘em. Just imo however.
