Jerry, you have to look close to see the puff on the hillside... lol
There are lots of 'short' cartridges that are better with a long action... especially if the throat is long or worn... no down side to along action 700 as far as accuracy goes...

If you can find some sand/dirt to land into, it is very easy to spot impacts... even with a light coat of snow

Here is the action, complete. The other bolt body has a magnum face, and there are a couple of handles that could be installed. Pulled an unused take-off .308 Model 700 matte finished 26" barrel out of the bin, and the darn thing screwed on and headspaced. Had to use a different recoil lug, but I can finish that one to match. The lug in the photos had been surface ground to insure that it was true, so it was a bit thinner. Easier to swap parts than to turn in the reamer to set headspace. Just what I needed - another project.
Now I need to find a suitable stock...

Here is the barreled action, ready to drop into a stock for testing. I have a HS Precision long action stock on a .300WM I put together. Could use that stock for testing this .308. Rather than firing up the park pot to refinish the recoil lug, I just blasted and cold blued it. Nice match with the factory matte barrel.

244 Ai is a 6mm Remington AI. Should be plenty of reamers around. Fairly common round. - dan
It's the same , the difference between the 244 and 6mm Rem was the slower rifling in the guns that were sold as 244's.
I am in the process of building one at the moment, just waiting on the reamer.

None. They are literally the same cartridge with different names. Only difference inbetween a 6mm Rem rifle amd a 244 Rem rifle is the barrel twist. The rename was a marketing ploy at that time, designed to feed off the 7mm Rem Mag which was extremely popular at that time. - dan
It may have been easier to convey which loadings were meant for the tighter twist by giving it a completely different caliber name than to find some other way of trying to explain which bullets worked in which barrels.
Then too, inch sizes have that Stars'n'Stripes feeling to them while metric sizes are Euro-trendy or Euro-decadent, so just as with 10mm auto vs 40 S&W there's that marketing spin.
Fire forming brass on a barrel only good for maybe 1000 rounds isn’t worth the AI benefit for me. The plain 6rem or 243win have done well. Even factory 243 win offerings from Remington stabilize 105’s from a 9 1/8” twist barrel. The 6mm space is very crowded
