.223 for bear, mountain goat, deer, elk, and moose.

Hey guys, has the quality of the aac 77tmk improved or is it still so so? I have seen some people say that the quality is horrible and I'd rather stick to 73 eld-m if that is true. Also, has anyone ever tried the pmc 77 otm's?

My first and last experience with AAC 77TMK was not good. Cases splitting, gas in my face, primers lifting. I did try but found about 40% failure rate on that batch. I pulled bullets and found mixed powders. Reloaded a few with my powder and cases were still splitting. Not even close to a max load. This was in a 223 chambered Tikka and a Wylde barreled AR15. Same failures in both firearms.

They didn't respond to me when I told them so I'll walk with my money.

This was my first batch they didn't respond until I posted it on Reddit and they messaged me after the thread exploded lol. Second batch has been fine but I've got tmks to reload now so this is probably my last batch.

Ok, thanks. Now would you guys rather hunt Michigan deer with factory 73 eld-m or AAC 77tmk?

As ElPollo said, I'd pick which ever you want. In Michigan I'd assume your shots are not super far. So I'd pick whatever is cheapest with a decent grouping. They will both kill fine. TMK is said to have a little more penetration (what I've seen on here, I have not done testing) but if one shoots a 1 inch group and one shoots a 1.5 inch group. Its irrelevant at a couple hundred yards.

What I'm getting at is either will be good to go at about 400 yards or so like ElPollo said haha.

Metal feed lips, follower spring seems quite stiff-

A little shorter than an AI 10 rounder-

Factory 4 round magazine. Look at amount of base that is presented to the bolt face (black marker is line from Mambamag)-

Dry cycling feeds fine. Will see about live soon enough.

Do these allow for longer coal?

Do these allow for longer coal?

I was going to ask the same…in case I get a wild hair and want to load some 88gr ELDMs.

No, limited to 2.337” COAL

I’ve got one of the new MT 223 mags on order. I’ll report back how it works.

For anyone wanting a hinged floor plate for a Howa Mini, there are a few in stock at Jefferson outdoors.

Mine has run flawlessly. Allows a 2.45 OAL.

The Mamba Mag 10 round Tikka 223 mag works well so far through three different Tikka’s.

Wanted to post this early black Friday deal I got from eurooptic. 1:8 twist, 16 inch barrel. Thread it and rock on. Price would be $575 with rebate.

.223, 74 grn Berger Jacketed Custom. Muzzle velocity 2950. 160 yards. Ouch.

What powder are you using to get those kind of velocities with heavier bullets?

Shot a forked horn Black Tail Deer with my RSS. 18” barrel. Factory ELD-M 73gr. 95 yards. My kid spotted it and it was the first big game kill for me with the .223. It worked great!

First shot hit low (shot just under the body and blew out the off side leg). My scope was foggy from a shit of down pour rain here in western Oregon, standing offhand shooting, and Buck fever. It jumped and when it landed it face planted. As the thread discussed, recoil was so light it was easy to stay on the gun and cycle another round and shoot it better as it looked like it might try to standup. Hit the spine and high lobe of both lungs. It looks like most the bullet hit the spine and blew through some giant chunks of lung tissue. No exit. Dropped immediately and started agonal breaths. No tracking and very soupy on the inside. The picture with my gloves hand is the entrance and of course the scapula. I couldn’t even see the initial entry. Found the jacket embedded in the flap meat/hide. The vertebrae that was hit turned into the texture of course sand. I couldn’t tell where I hit it when I first got up to it. No blood everywhere (it was a high hit so that makes sense), but it didn’t matter since it literally hit the deck on the spot.

Listened to a jvb podcast yesterday with a Hornady guy who talked about all the animals they shot in Africa with the 22 arc and the 22 creed. At the end of the show they concluded it's a whitetail and smaller cartridge. Jvb said it'll probably kill perfectly 9/10 times but it just doesn't have that margin of error for the 1/10.
