Questions for Larry Gibson for the most part; my apologies in advance.
I have had considerable success with the #29 flash holes w/ Red Dot & 308Win; cases that had previously shortened to the point where a push-type extractor wasn't even going over the cartridge rim. Really an outstanding solution, and I couldn't be happier.
- I am about to run the same exercise with belted cases (300H&H, 110gr jacketed @ ~60% load density). Obviously the belted cases can't shorten over time, but was wondering if any other benefit(s) of oversized flash holes w/ Red Dot would justify the minimal effort of modifying the cases? I have an ample supply of cases for this project and would certainly keep them segregated for these loads.
- Also, would the oversized flash holes be the way to go on Blue Dot (i.e. of "Seafire" fame) loads? Certainly higher pressures, but not traditional centerfire loadings either. I have had success beyond expectations with 223Rem & Blue Dot (using standard flash holes), but I am about to start a 308Win & Blue Dot load series - also w/ light bullets @ ~60% load density. How about the #29 flash hole with those cases ? (and keeping them segregated of course)
Best regards,
