This has been an AWESOME and very informational thread. . .thank you to all for your postings and pics!!! Just started going through it two days ago and have really enjoyed it.
I have a Howa Mini in 22 ARC and for the last year and a half have killed a pile of deer with the 80gr. ELD-M from up close to 250+/- yards, it's been a fun gun and a good kill'r. I recently saw a guy at a new range with a 6x47 Lapua target rifle single shot in the little Howa action and didn't think a .473 bolt face would be do-able. . .that got my gears turning. 22 Dasher came to mind at first and now that I've read through this thread the 6 Dasher is the end goal. Could any of you with the custom barreled rifles tell me the freebore you went with for shooting the 105 to 109 grain Sierra, Hornady, Berger bullets. This will be for a 6 Dasher with formed 6BR Lapua brass and my barrel is a 1-7.5 tw Brux #4 at 24". I'm in the gathering of components stage at this point and searching for a 'smith who will work on the Howa Mini (any recommendations welcomed) once I get it all sorted out for the build. I have little to no experience with the .243/6mm caliber in a rifle (had an XP-100 in 6BR 15" for a short time) but have been a long time reloader for .223, .264, .284, .308, and .358 calibers and all sorts of hunting handgun calibers, so this is going to be a new quest for me. I appreciate any advice given and thank you in advance for your time. Keep up the good work on this thread - PLEASE. I hope to contribute to it this coming season!!!
