And I’ll buy your takeoff 22-250 barrel

If another rifle shows up or another gun purchase I'll be in trouble
The 223 trainer escalated quickly.

I did get a preferred barrel coming in prison pink for the 22 Creed. The girls will love it Another 16".

Anyone using a 1-6 twist? Decided to give it a try to see if it'd help the 88's shoot better.

6tw for 22cm? Absolutely unnecessary unless shooting long solids.

Agreed, 6 twist is going to be rough unless shooting solids. Going to see some serious RPMs.

1:6” twist? For 88’s? You’ll spin them apart unless you’re running really slow velocity.

Now if you go shorter, like 12” barrel I think you’d be g2g!!

Haha. 1-7” twists spin 88’s apart. 1-6” is going to be a problem most likely.

At 360000-384000 rpm they’ll never make it to the target.

Better off going to a 1-8 or just keep using a 1-7?

1-7” twists spin 88’s apart.

Wow -- that's good to know. Sound like 1:7.5" might be the best recipe for .224 barrels.

1-7.5” is optimum.

Not all 1-7” twists make 88’s fail- just that it isn’t uncommon.

Donned the waders and hunted my favorite spot in a swamp this morning. This guy snuck up on me and caught a 77 TMK to the face at 12 feet. Destroyed him. I then proceeded to see 118 deer in 4 hours and not a single shooter buck lol.

Took my son out to fill a couple whitetail for tags before the season ended. Shot one with my 300 BLK and subsonic 194 Lehighs. Once I had dragged her up to the truck, I looked out and saw three more in a great location. First big game kill with the 77 TMK (but have shot hundreds of rock chucks, prairie dogs, badgers, etc).

405 yards
77 TMK at 3406 MV (20” 1:8 Proof)
Impact velocity ~ 2550

Down in seconds, maybe went 10 yards. No autopsy pics (was cold and getting dark), but lungs were absolutely shredded when I was gutting her.

As she lay. Exit side up.

After a season of using the 80 ELD-M’s in my 18” 22 Creed, since the 88’s and 80 X’s didn’t shoot very well at all, I decided to try out some new powder and bullets. Previously used H4350 exclusively.

Went with Ramshot Grand, which is right next to R26 on the burn chart, and Sierra 95 SMK’s.
Well after a few different seating depth and charge weight tests, this is as good as it got.



However I loaded up some 88 ELD-M’s with Ramshot as well. Suppressor was a bit warm, but managed to put up this group to the right of the SMK’s. It was better than anything I had tried with H4350.



After waiting for the suppressor to cool down and adjusting the zero for the 88’s, this was the result:



It wasn’t the result I was looking for with the 95’s, but this was the original bullet that I wanted to work anyhow. Very stoked on this!

Specs:
UM Tikka
UM Ace 18” 1/7.5 throated for 88’s.
45.5g of Ramshot Grand.
3020 fps avg.

I’m going to back down to 45.0 and see if the results are the same and land right at 3000 fps. Had a slightly heavier bolt lift on some of the rounds at 45.5.
