I don't know it all. I don't claim to know a lot. I'm not an expert, and I'm not a super competitive shooter. I'm familiar with firearms and enjoy them, and I'm also not made of money. I clean my weapons everytime I shoot them. My name is Brock and I'm tired of hearing crap about steel cased ammunition. Lmao, now that that's out of the way, why does EVERYONE repeat that steel cased ammunition is crap? I understand if you're squeezing the last MOA or 1/4MOA of accuracy out of your bench gun. But I swear, if I hear another freakin person at the range say you really shouldn't put steel cased ammo in your rifle, I'm gonna flip out on somebody haha. RO today said that. Well, considering I have my rifle set up for run and gun type stuff (Lightweight, RDS, CTR stock, etc....I'm probably not concerned as much with hitting a 2" steel plate at 4 gazillion yards. It is dirty. I get it. But it's not 50 bucks dirty. Because that's what I saved by shooting it instead of brass at the range today. It's unreliable. Riiiiiight. Maybe in your gun, with a barrel that you couldn't pull a greased string out of a cats butt with. If I can group 2" at 100 yards with it, because I care less inside of that, then who cares? Here's the thing Mr. RO who wants to tell me how to run my damn rifle.....I've put probably 5000 rounds through mine, about 80% steel cased ammo, on courses, running it as hard as I know how to run it. I've never had ONE single malfunction. Not ONE. I know that I will have one one day. But that's pretty damn good to me so far, and I've saved enough money with the steel to buy another rifle if I want. It'll damage your extractor.....sure dude, and a loaf of bread with damage your car if you run over it. It's SOFTER STEEL. Rounds will get stuck in the chamber because of the lacquer coating. Um, not mine. Ran about 500-600 rounds through mine with a slidefire in about 45 minutes and smoke was pouring out of the handguards to the point where you couldn't hold it. I know, I know. But it's mine and I'll destroy it if I want. I buy guns to shoot them. I buy guns to get BETTER shooting them. I'm no expert shooter, but I've come a long way since that first shot. So if mine have dings, scratches, dirt, oil, carbon, or anything else on them, so be it. Shows I don't take it in an indoor range, shoot 3 mags off a bench at 25 yards with some 80 dollar a box Hornady (good stuff, don't get me wrong, just not at 25 yards. Makes negligible difference) and call it a day. And then tell other people how to run their crap. Dude. That gun has never seen sunlight. STFU and shoot in your lane. Or stand there and watch from behind on your chair. I don't care, but let me live my life. Rant over. Thanks for listening. I'd go buy a new barrel now but wait mine's still running. Guess I'll clean her. She's been bad.
