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

Rifles are made to SAAMI and CIP approved specifications. Factory ammunition is made to SAAMI and CIP approved specifications. Rifles are made to work with factory ammo. Magazines are designed to work with factory ammo and have minimal issues loading/feeding factory ammo.

If you want to use custom ammunition built outside of SAAMI/CIP specifications, you will need to do custom work to get these things to work in a factory rifle. If a little magazine work is all you need to do, consider it the price you pay.

Using the 88 eldm over using the 77tmk in a 223 is the same as using a 230 over a 200 in a 308. It really is a huge jump in weight and length (~15%) which most factory rifles are not set up for even if they have the right twist barrel. Whether or not the cartridge has enough horsepower to effectively launch the larger bullet is an entirely different discussion.

Good point.

88 grains is a lot to ask out of a 20” .223.

Thing is the ctr mags work fine so they could offer a magazine for the short ar length rounds that still allow you load 75’s and 88’s. But yea I get it most people shoot factory ammo and making tweaks for those who don’t is part of it. No biggie.

Yes, one thing that makes me sad about my .22-250 is that it was built by an older gentleman before the heavier bullets became popular. So, it has a 1:12 twist. It’s built on a Mauser action though, so if I ever wanted to put on a faster twist barrel, I’d have lots of room for longer COAL.

I recently swapped out a 1-10” Tikka barrel for a 1-8” so I could shoot 75 ELDM. It really worked out.
