88 TMK Loading Thread

[Schmo]

I was looking at 22GT today too. I have some 22 creed barrels to shoot up and I'll probably move that way.

22 Creed just a tad too overbore for me. I’d rather a fast twist 22-250 or 22 GT I think

22 Creed just a tad too overbore for me.

Totally...I went that way (and 6mm Creed) because I had a ton of 6.5 creed brass to resize.

I’d rather a fast twist 22-250 or 22 GT I think

I had a 22-250 first and with big bullets and fast twist it's basically the same thing as the 22 Creed.

Rechambered 18” Tikka 22-250 to 22 Creed

88 TMK
H4350 38.5 grains
Alpha LRP brass
2.610” COAL
2950 FPS or so (shot 6 over the Garmin)

This thread is enough motivation to spin on my 22-250 barrel, order some brass tonight

Encouraging seeing everyone’s results

What action? I believe @The Guide has an extra T3x prefit on order.

That 260 is an origin but I also have a tikka that could be used haha.

I had to buy two of the 22 GT Tikka barrels to make the group by work. If these 88's shoot as good for me as it looks like they are shooting for others, I may just get rid of some other 22 cal guns and just do 22 GT and 223 but before I do that I'm going to try and compare the 88 TMK in the 22 ARC (22" and 16"), 22 GT (20"), and 22CM (22" and 20") to see how they compare.

dont count out a 22 dasher or 22 bra. I am loving my 22 dasher so far. hell even a 22 br would be fantastic. feeds wonderful even with lighter bullets from an mdt 6br mag

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.

Not with 88 tmks but I took my 95smk load to 3150 without pressure signs. Took the 88 eld to 3250. 18inch barrel on a Kimber which tends to show pressure. H1000 showed pressure at 2850 and 2930 respectively with those 2 projectiles in the same gun. I havent found pressure with rl26 but velocity had me concerned enough to back off a fair bit as speed was still good. Ive got enough RL26 to see out this barrel.

Unless you want all the speed, I think you will like the GT. My 6gt might be my favorite gun currently. It just hammers.
