I think I saw a blind squirrel running around here with a drawing of a Satern 45 Raptor barrel and an SRM-25 magazine spacer.....stay tuned.

I can load a dummy round and check feeding. Don't you have one of Bob's .30 SIL moulds?
Standard GI mags may be a problem depending on the bullet length and nose diameter. The noses tend to bind on the guide rails a little bit in my experience and either spread the mag walls or try to overlap each other. The Pmags are pretty much good to go except for the nibs at the top of the rails, which file off easily enough.

This is starting to become FUN now that all the head-scratching and tinkering are done with regard to the load and functioning of the rifle. Tonight I put another 15 through the Magneto Speed and then gleefully took it off since I don't really need it any more. Average speed 1068 fps, ES 29, SD 10.1, put 10 into 3/4" at 50 yards with only the handguard supported (awkward angle getting around my range attenuator). I think tomorrow I'm going to head to town and shoot it at 100 yards and see what it will do. I was impressed to discover that where the sights are set it shoots 1/2" low at 15 yards, dead on at 25, and only 1/2" high at 50. All bullet holes were perfectly round, no tipping whatsoever. The bolt locked back firmly after every five I put in the magazine. After all that, I proceeded to wail on the 3x4" swinging gong at my 50-yard backstop. This rig is deadly accurate and hits with authority! You guys would enjoy the heck out of one of these if you can find somebody to make a good bullet mould.
I'd say the .45 ACP is even more fun to shoot, but it isn't quite as accurate (yet) and cost me more than double what putting together this 300 BLK did. The jury is still out on which one will suppress better, maybe we'll get a report from L1A1Rocker on his soon. I've read on a forum somewhere the comment that if a person is trying to choose between the two calibers in an AR-variant carbine, they should just get BOTH and I'll dang sure back that up. They both have advantages and are huge fun with cast bullets.

Even MORE Dark Side kind of fun with a Mystic and Slide Fire........
I'm off to the range today with another 300 shooter. I have Lee 155s (mostly) over H110 and 4227. 311672s are loaded for my tighter chambered pistol barrel and his excessively tight 1-10" twist McGowan. He also shoots 311332s. All of these are supers, and we'll shoot 200-500m.

I haven't played with supers yet at all, but I have two moulds that ought to fill the bill nicely if I decide to.
This morning I hauled the carbines to town and stretched their legs a little. The .45 ACP turned out to be miserable with my cast loads at 100 yards, literally shooting 2' patterns. Ran some Winchester "White Box" stuff through it and got about a 4" group, so it ain't the gun or shooter, it's the nut behind the casting bench. Now the 300, it impressed me to say the least. Right out of the gate it was holding 1.5 MOA, and did so all day. After putting four groups of ten on paper and making a slight adjustment to my $15 Tasco Pronghorn scope, I packed up and checked in to the long range where I spent a couple hours BSing with the RO and a couple of dedicated long-range guys. They have 14"x10" swinger targets set up at 200 and 300 yards and I ended up shooting another 50-odd rounds that put about a 4" silver circle in the middle of one of the 200-yard swingers. The drop is alarming, though, somewhere around 18-20" from a 100-yard dead zero. It took me four rounds to get the hold-over just right. The RO didn't want me to go to 300 because of the drop and the fact that that berm is off to the side, more in line with one of the other ranges and misses/ricochets can be dangerous. Anyway, it was fun lobbing shells. L1A1, you gotta go out there with me again sometime and pound a little steel once you get your 300s squared away.

In that I have quite a lot of range pickup 9mm brass, I've considered what platform to shoot it from. The more I shoot the 300BLK, the LESS likely I am apt to go forward with 9mm unless its a CZ-75 or S&W Shield.
I'm sort of hijacking Ian's thread, but hopefully the info will be useful to him.
At the range yesterday, we shot (5) 300s. (4) were 16" carbines and the other a 10.5" pistol. I don't recall shooting 200m at all as we were spending time knocking down silhouettes 300, 385, and 500m. I had loaded Lee 155s:
15gr 4227 and crimped into the crimp groove for the pistol
15.8 H110 and crimped into the front driving band for the carbines
17.1 MP300 and crimped into the front driving band for the carbines
I also had:
15gr 4227 under 311672s crimped into the middle of the front band for the pistol
19gr AA2200 under Lee TL160s seated to 2.050" crimped behind the first microband for the carbines
Bob had 311332s cast from lino over 296 for his Hardened Arms carbine and some 130 and 150gr Hornadys over 296 for his McGowan with ridiculously tight chamber.
Of particular interest were the shorter Lee 155s and 311672s. They fed perfectly from the tight chambered pistol and seemed to group well at 300m. Bob had (previously) complained of .310" leaving lead rings (311414 and 311332) in his McGowan barrel and was convinced that he needed .309-.3095". I loaded his magazine with 311672s (L&S .311") and they chambered without marking the bullet. He shot 10 or 15 and then I had him try the short Lee 155s also S&L .311". They chambered, fed and fired without a hitch, and left no lead rings! That left him scratching his head.

Unless you're restricted to very short range recreational shooting or just DIG the idea of a 9mm AR, I can't see choosing one over the 300 BLK. I love my .45 ACP carbine but it hits HARD at short ranges for the little recoil it produces, the kind of hard that knocks down heavy steel, bowling pins, etc where a 9mm subsonic....not so much. Even supersonic 9mm, not so much.
I suppose those carbines were shooting pretty well to be tackling silhouettes out to 500 meters, how hard were they hitting down range? Standard, 18" plates are a buggar to knock over sometimes unless you wing one on an upper corner.
