The firearm thread

[jono035]

Just cranked out a few hundred rounds of .45ACP and decided to time myself. Ignoring stuffing around with primers and going at my normal plodding pace (pausing for a second at the top to let the powder drop complete, pausing for a bottom with the primer ram up) I managed to get through 50 rounds in just under 2 and a half minutes.

It occurs to me that I may need to start shooting more in order to be able to indulge my reloading hobby

Also found out I can't get a holster insert for the Kimber due to Double Alpha not making one that will fit the polymer frame. So I 3D printed one. Will give it a try on Sunday, but so far it has held up to 30-40 'draw, fire, show-clear, unload, load, ready, holster' drills without showing any stress of any kind.



Starting to turn into a bit of a 'when all you have is a hammer' type situation, here...

Been thinking about getting hold of a rifle in .45ACP to have a play with suppressed... Would probably make a pretty hilarious possuming gun and I broke the trigger guard off the Stirling, so it probably needs to be replaced. Actually... Polymer lower for a Stirling bolt action... Can't be any weaker than the original muck-metal piece...

I have less than minimal interest in having fun with firearms but I stumbled upon this.



Impressive shooting.

How odd... Someone mentioned that to me at the range today but I hadn't looked it up yet.

Cheers for the link.

whatisit?? Rob munden? Fastest reload? 6 shotrs on 3 targets? Fps russia goes to whitecastle?

I'm building a de lisle carbine. They're cheap enough. Just build on a shot out Farm hack 303 mine should be roughly $800 all up when finished. They're supposed to be completely silent. The loudest part being the old 303 action.
Another option I'll attempt in the future is use some of the left over barrel and build a suppressed 45acp upper for an ar15.

I've seen the effects of a 185 grain swc on possum. Put it to sleep instantly. A body shot would have been messy

Dunno why that didn't occur to me, I wanted to do that a few years ago.

How faithful are you trying to be to the De Lisle style? It's a 3" diameter can on the front with the barrel at an offset, right?'

I've got a slightly monkeyed with .303, even. I could quite happily 3D print myself a .303 to 1911 magazine adapter...

Where did you get the barrel from?

[jono035]

Also, powered through another 250 rounds on the press with the bullet feeder, no issues aside from some large primer brass getting mixed in and a 9mm case hiding completely inside a .45 case that damn near snapped my depriming pin...

Took the Kimber and 3D printed holster insert to the range today, shot about 100 rounds in 4-5 stages, performed nicely.

Also made myself some pretty sweet looking ammo boxes. The text on the top is just embossed half a mm. It looks pretty nice, really. They take about 12 hours to print both pieces (they're reasonably sturdy) and then just need 2x M4x40 machine screws for the hinges. I probably could have made them snap together but, to be honest, I really just couldn't be bothered. All up, I think they're using about $5 of plastic or something? Easy to adjust for other cartridges or numbers of rounds. If anyone wants one then let me know. I've even got a variety of colours of plastic...

I hadn't thought about a 3d printed mag adaptor, I was hoping to either tack weld or create my own mag attachment inside the old mag. I may have to look in that when I reach that part.

To be honest I'm not following the original at all. I have a stainless barrel blank from Vulcan barrels Christchurch (who did a superb job) it's long enough to do 2 or 3 rifles. Robbie Tiffen will fit the barrel, profile, modify the extractor and thread the end.

I'm using a #1 mk3 action I picked up for free.

the stock I'm going to use is a folding one from an ak47. I'm making an adaptor to fit this using a plastic spacer I'm filing into shape.

I'll be mounting a weaver rail over the bolt.

as for the suppressor I'm going to attempt to make my own one. I'm not expecting it to be nearly as quiet as the original as I won't be porting the barrel and the suppressor baffles will be washers rather than concentric spirals. also to keep it light weight the suppressor volume won't be as large as the original. it'll still be pretty quiet though. due to the round being subsonic and I'll be loading with greater or at 230 grain projectiles

Nice. Robbie mentioned a few oddball projects like this when I was talking to him about my suppressor. Did you think about getting him to build up the suppressor? I'm pretty happy with the one he made for my 300 Blackout. Wasn't cheap, though!

I've got an old .303 here and I've printed some half-assed .22 magazines before that mated into the well of my Stirling bolt-action nicely, just they didn't work because the feed lips were a bit crap because of poor design on my part.

I'll have a quick look tomorrow and see if I can come up with something that will work for the 1911 mags I have on hand.

Edit: Hell, given the extreme lack of recoil from what I've seen of those things and the relatively short useful distance due to the subsonic rounds, you could probably 3D print the bloody scope rail, too.

I did think of him for the suppressor build and when/if my suppressor fails or isn't good enough then I'll be getting him to build me one. I have one of his generic AR ones and I'm more than happy with it, I imagine this one wouldn't be nearly as cheap.
when I do my 45acp AR build I'd be tempted to use one of his as it'll need to be a little more hard wearing due to being a semi action.

I've seen aluminium rails for $80 for the #1, unsure how stable they'll be as I believe they clamp onto the bar that goes over the bolt, I may screw mine on if that's the case as I don't want it to slip. it'll be a bush hack rifle, something I can put in my pack for a few days, get knocked around, then pull out in my block, flick the stock out, attach the suppressor, and attach the scope and away I go.

if you do come up with a 1911 adaptor I'd be very interested in the results.

Half assed attempt after a couple of hours of mucking around with Solidworks. It occurred to me after getting out my .303 that the only mags I have are double-stack, which only fit right at the absolute back, which probably isn't a great place to put it.

I grabbed the dimensions off the net and made a rough model to play with. The top section of the double stack mag is the same dimension, at least.

So yeah, looks like it shouldn't be too difficult. Would either need to attack the frame with a dremel or get myself a single stack to test it, though.

that's pretty cool.
I was planning on putting the 45 mag up the front of the enfield mag, I believe when I've fired the shot the round would sit in the bolt then drop behind the 45 mag. thet way I'd be able to fire 2-4 shots without having to worry about picking up brass, maybe if I lined the mag and receiver with felt or velvet type material it would stop the brass from tumbling around noisily.
However a plastic mag replacement for the enfield mag will be pretty quiet.

I should have the rifle ready to put together in around 8 to 10 weeks if I get enough time. I'll start thinking about the mag adaptor at that point

That's a good point, I would have printed the piece hollow anyway, so might as well print it with the bit behind the mag hollowed out as a brass catcher.

Could always just try to print myself a single stack 1911 mag to test with...

What programme are you using Jono? (Edit on reading properly I see Solidworks - I use Inventor 2012 or something)

And what formats does the printer take?

Yeah, Solidworks 2013 at the moment. We've got a couple of licenses at work but I've got a slightly dodgy version at home.

The printer itself takes g- code. In my case I use a program called Slic3r to generate that from .STL files. Apparently it also takes .OBJ and .AMF... There are also alternate slicer programs that may take different formats but I don't really know much about them.
