duckhunter175 Report post Posted February 4, 2018 Any idea on your CBTO for that 80gr? Mine was a Savage model 11 vt, a heavy barrel model only available from Dick's sporting goods. I had just bought it for a cheap coyote killer and hadn't intended to build on it but when I sighted it in I discovered it had a bent barrel. Ratter than dealing with Savage I decided I should just fix it up the way I wanted it anyway.I ordered a m40 Bell & Carlson, and a Douglas air gauge 26" 1/7 twist rem varmint contour barrel. Rather than deal with the feeding issues mentioned above I ordered several Savage magazines intended for a 6.5 Creedmoor. The Creedmoor and 22-250 Ai have identical case taper and just a few degrees difference in shoulder angle. Just switched magazines when going from fire forming loads to AI loads and never had any issues.Don't remember how the rifle was throated but I know a 53gr V-Max could still be seated into the lands for fire forming. The pic I've attached is a 80 gr Berger VLD seated .005 off the lands next to a 55 gr Hornady factory 22-250 load.IMG_20160921_165541017.jpg Share this post Link to post Share on other sites

Big or Bust Report post Posted February 4, 2018 Mine was a faux Remington 700 Ti. 22" 1-8" Pac-Nor, mountain rifle contour dupe. It was a backpack rifle. I throated it for 80 Berger's to kiss. I was running 80 Berger's at 3,250 from the 22"... Best powders were in the RL-19 or so burn range.. Killed coyotes forming brass, killed all with formed... Killed my best coues buck at about 500 yards with said load. Dead on feet. Great cartridge, fun to shoot, great bullet choices... 1 Share this post Link to post Share on other sites

The one print I've seen showed a throat (W measurement on the print) of 2.1067- that was measured from the rear of the case as the 'datum'? If you want to specify a longer throat how is that accomplished? (Curiosity is getting the best of me). Is the smith taking a dummy round for measurements and then reamer the chamber and then ream a longer throat? Share this post Link to post Share on other sites
Big or Bust Report post Posted February 4, 2018 I always give the Smith a dummy round taking into account magazine constraints and a bit of flexibility to shoot other bullets if the want or need arises... I'd have to go look at old notes but a factory 700 action/mag is perfect for the .22-250 Ackley.... 1 Share this post Link to post Share on other sites

If my math is any good there shouldn't be an issue getting the heavier bullets to mag length if they are seated down to neck/shoulder or slightly further in.

Is the smith taking a dummy round for measurements and then reamer the chamber and then ream a longer throat? I always buy the reamer myself and send a dummy round in with my order for the reamer. I also discuss what I want to accomplish with the cartridge with my reamer designer. When you receive your reamer check it out against the blueprint. If everything meets your specs, you give the reamer to your gunsmith. The one time I let my gunsmith order the reamer something got lost in the translation. Whoever does your reamer will also supply you with print. If they don't ask for one. 1 Share this post Link to post Share on other sites

They make separate reaters that pilot off the bore and will increase the throat depth after a standard chamber reamer has been used. 1 Share this post Link to post Share on other sites
duckhunter175 Report post Posted May 13, 2018 So she is almost done!! 75gr Amax, 80gr ELDM and 90gr Sierras are on hand. To make this a true replica I need to get the bolt jeweled. Anyone have a recommendation where I can send it off to? Share this post Link to post Share on other sites
PRDATR Report post Posted May 13, 2018 LRI has done some fluteing on a couple of bolts and they do nice work. I would give Chad a call or shoot him and Kalli an email. They also have a FB page. https://www.longriflesinc.com/search?type=product&q=Jeweling 2 Share this post Link to post Share on other sites

Anyone have a recommendation where I can send it off to? Jon Trammel in Breckenridge,Texas does it all. Excellent accuracy smith, phone:254-559-3455. When you fireform seat the bullets well into the lands and work with the bottom load in your reloading book for a standard 22/250. Do two fireforms before working on full loads. I found best accuracy in mine seated into lands at .010". Again I was shooting single shot. 1 Share this post Link to post Share on other sites

Then sending the bolt off for jeweling-- so it'll be another few weeks before I can spend some serious time at the range! Long awaited though! 1 Share this post Link to post Share on other sites
