88 TMK Loading Thread

Nah. You just seem to get all the bum barrels. Grin.

There might be a carbon ring in the middle of my barrel.

Just got an order of 88 Sierras that I'm planning to load w Varget. 223 Rem barrel is 17" and 1:7, bullet seating at .025" off will max out the longer MDT magazines. Looking forward to shooting these bullets!

For the shorter barrel 22CM guys, anyone tried RL26 yet? Last summer I started loading 80 eldX for my 22CM and settled at 45.4 grains and 3,500 fps mv. Extremely accurate/same vertical poi at any charge, went as high as 45.9 with no pressure @ 3,590+ fps. Barrel is 22 inches and 1:8.

Anyway, RL26 for 88s in a shorter 22CM w 1:7s makes sense to me.

Happy to help.
Just make sure you’re measuring your own chamber. My throat length and rate of constriction might be wildly different from yours.

Yes, after measuring the 88s in my chamber I can seat .025" off to fit loaded rounds in the older 2.50" MDT mags.
