Albroswift Posted May 1, 2019 Author Report Share Posted May 1, 2019 Friend built another AR-40 pistol last night pretty much copy of my .40 out of the lower he milled last week with the 5D Tactical Pro Jig. Start to finish starting with the stripped lower a little over an hour and a half Probably could have cut that time if he hadn't put the FCG in every way possible before coming up with the winning combo. I've never done one start to finish before, usually get a few parts, put together, get a few more.... two setbacks that cost some time, the set screws that hold the ejector would not screw in to the point of contact. threads were not clear through and didn't have a bottom tap that matched the thread pitch so spun up a couple spacer buttons on the lathe, easy fix. Bigger issue when we tested function bolt would only retract about 1/4", spent the next hour and a half like monkeys and a football, buffer tube on, buffer tube off, upper opened, closed, smoothed out every possible internal part before we figured out the charging handle was contacting the buffer tube alignment adapter (I believe it's called) Adapter was out of the parts bin, never used before, probably a cheap POS. Filed about a billion of an inch off the top and bingo. Check the simple stuff first, Duhhh! Quote Link to comment Share on other sites More sharing options...

Albroswift Posted May 2, 2019 Author Report Share Posted May 2, 2019 Dies showed up Monday, the new upper today, got the brass, case gauge, most of the Aero lower together (waiting on a real adapter plate!) Case gauge actually has rifling in it, should take the guesswork/ slugging / marking paint out of the reloading process! Most fun you can have in a AR-15 magazine Quote Link to comment Share on other sites More sharing options...

Albroswift Posted May 5, 2019 Author Report Share Posted May 5, 2019 Pretty far from pistols and revolvers, but you guys don't seem to mind... Got a range report for the 458S Cycled flawlessly, even loads that wouldn't lock the bolt back. Kudos to the Tromix shop, nice to get something that works right out of the box. Started with some 300 and 400 gr bullets, H-110 and Data-2200 powders. What I had in stock. Neither powder worked well with the 300's, SD's all over the place and when I got to top 3rd of the load chart started patterning instead of grouping. The 400's were a different story, Speer FPSP (Flat Point Special Purpose) jacketed 45-70 bullets with an extra crimp groove for shorter COL loading. At about the middle of the load date the SD really tightened up, 1440 FPS, then started to open back up at 1500 FPS, no signs of over pressure probably could max out this powder/ bullet combo 1575 or so, but really liked the SD at the middle of the road velocities. Put a Leupold VX II on it for load development, no idea yet what I want for final optics but with a cantilever mount the 3X9 may be an option. Not as sexy as some of the other options but a rugged scope, crystal clear, ran it for 20+ years on the BAR 338 until I upgraded that last season. (Hey, gold ring shiny scopes were the in thing 25 years ago!) 400 gr Speer FPSP Data-2200 powder about half way between starting load and max load A little closer to the top, a grain or two below max Quote Link to comment Share on other sites More sharing options...
98Z5V Posted May 5, 2019 Report Share Posted May 5, 2019 That's one hell of a load!!! Awesome! Quote Link to comment Share on other sites More sharing options...
Albroswift Posted May 5, 2019 Author Report Share Posted May 5, 2019 (edited) yes, figure AR 15 62 gr bullets at 3000+/-, same platform 7 times the bullet and only loose 1/2 the velocity. Just over half the pressure. used a AR10 length tube, whimpy spring, light buffer, and a stepped spacer to set travel Edited May 5, 2019 by Albroswift Quote Link to comment Share on other sites More sharing options...
Albroswift Posted May 14, 2019 Author Report Share Posted May 14, 2019 Added a PA cantilever mount (what a beast!) and actually the gold ring is a fair match for this particular shooter, 3x for shoulder work and 9x for the bench. May just leave it that way, shooting some 400 grain overlapping groups at 100 yards. Quote Link to comment Share on other sites More sharing options...

Albroswift Posted May 23, 2019 Author Report Share Posted May 23, 2019 Gotta quit spending money, but... Leupold started rattling and had a little fog in it! Spent 20 years on the BAR 338 WinMag but only lasted a couple sessions on the 458. So Gold Ring is going back to the maker for a tune up and the SOCOM gets a Viper PST 1-6x24... I'm impressed with the PST, beefy...crystal clear from 1X to 6X, Milrad retical. I 458 uses a 308 sized rebated rim so the 308 boresighter worked perfectly (with a small mod): Quote Link to comment Share on other sites More sharing options...
sketch Posted May 23, 2019 Report Share Posted May 23, 2019 (edited) thats neat the (bore sighter ) Last time i brought the .458 for show and tell, we tried 100"' but didn't ring steel.. it was their first time. 😁 Edited May 23, 2019 by sketch good shits!

Albroswift Posted May 23, 2019 Author Report Share Posted May 23, 2019 (edited) Out at the gravel pit Saturday I was exploding potatos at 100 yards offhand even with a little fog in the scope. We also blew the "Mongo Scarecrow" a quart sized tannerite type exploding device I've had laying around for many years.

There aren't any other variations, brother. None out. I've had my .45AR for 8 or 9 years now. I finally switched to the CNC Guns dedicated lower, and I'm running M3 Grease Gun mags.

sketch Posted May 29, 2019 Report Share Posted May 29, 2019 (edited) well range day was kinda havoc with 4 new rifle/pistols. the oly ran ok for a mag or two and handed it over to the vet. one and done? problem later. '40 cal pistol had some mage issues due to feeding.same as the .9. problem later . x39 single fire again.. problem.. 308 worked great after break in but the cheap flip sights had me aim a foot low @ 60"' with no more adjustments. fix add the red dot! doing some buffer and spring changes on the 45/x39. longer on the 45. seems the gas charge block is nocking metal off my lower/ reciver tube and got stuck under the trigger. pic below some yellow paint on the lost metal. x39 shortened the buffer a tad we will see? all that and still had fun with the vet! never go to the range without a challenge! 🍻👍 Edited May 29, 2019 by sketch good shits!

Albroswift Posted May 29, 2019 Author Report Share Posted May 29, 2019 The range loves to point out shortcomings. Gravel pit can be an even more brutal master! As I've posted elsewhere, the 40 does not like cheap magazines. I'm sure you will finger everything out! Quote Link to comment Share on other sites More sharing options...
