UMC 300 AAC BLACKOUT 115gn CTFB by REMINGTON REVIEW (CMMG UPPER DPMS LOWER)

I am sorry I have not tried any but I am sure it will do fine with out a suppressor – Charles

Have you tried 220gr subsonic loads in your same configuration? I ordered the same upper and was wondering if subsonic loads would work in that upper without a suppressor. Thanks.

Thanks for the info I think I can move it forward that Much – Charles

You need a proper scope mount for Ar rifle, try American Defense Manufacturing. That scope needs to be moved forward at least three inches to get the proper check weld. Without a consistent weld you can't get good accuracy.

Yes PlainView is just north of me I havent tried subsonic yet I dont have a silencer yet Thanks for stopping by – Charles

looking at the back ground – you have to be close to Plainview tx – do you reload sub sonics in your 300 bo

Thanks for the info – Charles

I get mine at Cheaper Than Dirt for $10.36 a box 115 Gr. Rem UMC or $11.86 a box for 147 Gr. PNW

I did not know they had them in stock Thats Great Thanks for letting me know. Ive Made one bullet from 223 Brass and it worked but at 12 a box thats the route I'm going I'm Happy with the Pattern I got I'll Save the brass for winter reloading Time – Charles

Charles, you need to jump on that 300blk Rem UMC. Midwayusa has it in stock for the past few weeks. For $12 a box I shoot the heck out of it and then I got a bunch of brass for reloading. Have you tried making your own 300blk brass from 223 stuff? Its pretty easy. There are a bunch of vids on YouTube regarding.

Thanks for Stopping By I'm in the Panhandle of Texas Where you can see New Mexico Blow Thru every Couple of Days – Charles
