New to 22 CM Questions

Very much a newb to this caliber. Was in SD for a week and, well, they talked me into getting one before I come back next time. After some research, I'm looking at OMRifles Tikka T3X barreled action. All I'll "have" to add is chassis to complete. Seems reasonable, compared. Haven't' found anything too negative about them.

My current questions are: For 200-600yd yotes, is 20" barrel enough? I will suppress so trying to not be too long. Second, order 7 or 8 twist? Also, seems best to order a 5/8x24 to use beefier cans. Will I have to do anything to magazine to feed correctly? They ship with 6.5 CM mag.

20 inch is fine. 8 twist if you run the 75-80 grain bullets. In a 20 you should be at about 3200fps. I run 88's in my wife's 26 inch gun at 3270.

What he said…. . I had the same questions.

I didn't answer the mag question your are fine with that mag it ships with we run metal mdt, poly magpul mags and never had a feeding issues. It's one of my favorite rifles. I'm building a 20 inch for my self. Unless I end up getting a 22 gt. The wife shot two antelope with it this year, 1 and 117 yards the other at 349. I attached the pictures of damage. The lung picture is at 349.

I run a 24" 22creed. It's the rifle in the picture. Shot that deer with a 80.5 grain berger fullbore at about 3400, was dead within 10 yards of where it was shot. This year I went to a 77 grain TMK at 3550. Dropped a buck where he stood at 140 yards. Pictures below, no exit but entrance in the cavity was huge.

Mine feeds from a standard SA Hawkins Hunter mag with no modifications to the feed lips.

I love this rifle, but don't tell the guy who talked me into building one LOL

Edited: Mine is 7 twist

88 wasn't fur friendly at 320 yards. Hit him farther forward than I wanted but he was very very dead.

I built my 22CM as a 1/7 twist for shooting the 95gr SMKs, which it did extremely well. It did however have a tendency to blow up lighter bullets due to the extremely high RPMs. I built my brothers as a 1/8 twist and it shoots everything up to 88ELDMs very well. My rifle was put into an MDT LSS-XL G2 chassis and used the MDT metal mag. Feeding and function are flawless with this combination. We built my brothers into a KRG Bravo chassis which also feeds from AICS mags. Both rifles were built from S/A Rem 700s. It's a fun caliber with the heavier bullets, but I have since moved on to 6mm with mine. Good luck with your project. It should make a fine Yote rifle.

I built my 22 Creed with a 7.5 twist Bartlein. So far, it hasn't blown up any bullets from the 65 Sierra to the 85.5 Bergers. I'm currently running the 85.5 Bergers at about 3,250fps with H1000 in SRP Alpha cases. The 80.5 FB Bergers shoot very well with RE17 and have single digit SDs. I keep them at 3,300fps but higher velocities may be possible in the 26" tube.

Earlier this spring during a lull in activity, I was cleaning up the shop and organizing for the impending rush of projects coming in. As usual, I got the vault straightened up first just to see what I might have available in stock. Low and behold, I found a .22 caliber barrel with what I thought was stamped as a 7" twist. Not my usual purchase so I ran a rod through it to measure that twist and yes, it was a 1:7".

Interestingly enough, I already had the Alpha brass and of all things, Hornady 90 grain A-Tip bullets! I checked the reamer drawer and found that I had the .22 Creedmoor reamer and gauge ready to go. Well, there went the 'free time'!

The load I worked up was the result of wanting a cooler burning powder since I had a longer barrel (26") and I was going to use a suppressor. A full case of VVN-160 under those 90 grain A-Tips yielded a slightly lax 3200+fps for an accuracy load.

Fast forward to a bit ago and a text I got from one of the farmers I help when needed. Evidently, two coyotes had discovered his rather large chicken coop and made a mess while feasting on his layers. They even got a couple of the roosters!

I arrived during a rather cool day loaded down with my practical shotgun and what else? My brand new .22 Creedmoor. The farm was a little spread out so a longer shot was to be expected. We followed some of the tracks and feathers across the field and down into a shallow gully leading towards the woods. From the coop to the woods, probably 950 yards. On the walk back, we passed another small woods on his property with a wooden tree stand, maybe 10 ft. high just in from the edge of those woods. Thankfully, there was a manufactured ladder bolted onto the tree.

I napped for a short while, had a bite of supper then grabbed the rifle and rangefinder to make my way to the tree stand in the lingering daylight. I wanted a couple of references for distance from the tree stand to the woods. I settled in to wait.

There was a very nice moon providing some illumination, behind my back fortunately, just enough for the shot.

In they came, drooling I'm sure with thoughts of another meal of fresh chicken. They paid no attention to me, so I shot the trailing coyote full in the chest, rapid reload and shot the leading dog full in the face as he looked up. The carnage was significant.

Checking the rangefinder the next day indicated both shots were about 310 yards close as i could tell.

I need to try this out on spring prairie dogs!
