300BlkTalk

This morning before leaving for work I measured the neck diameter of a factory round (Hornady Black which chambers easily) and one of my reloads with bullet not yet pulled. The measured EXACTLY the same (I think .330 going from memory). The diameter at the base was exactly the same also. Trying to e...

OK now I'm really stumped. I decided to take a fired case, put in a Lehigh CC "long", mark it with magic marker, and slowly push it in to the chamber to see how far the rifling pushed it back. Well of course it got stuck hard and I had to take a rubber hammer to open the bolt. So I knew th...

Yes, the Lehigh is the controlled chaos. I loaded it per Lehigh specs and it ran into the rifling big time. Looks like I'm going to need to "shell" out big time for all these tools and gauges to figure out BLK is going on.

Thanks very much. I understand (before, and very clearly now) that OAL is different from what a chamber will accept. It looks like that Lehigh will need to be loaded a lot shorter than even 2.1. I reckon I'll have to invest in the Sheridan Gauge. I do think that Ruger chamber (leade) is very short. ...

I'm having to pull a bunch of bullets because, when loaded to max OAL or anywhere close to it, they will not chamber in my RARR. This has occurred with 110 grain Lehighs, 190 grain HPBT, and 150 grain SBPTs. If I go to load them deep enough to chamber, the pressure, per QuickLoad, goes out of sight ...

I tested and sighted in my 10.5" AR pistol today with JP adjustable gas block. JP says, I think start with two turns open. It took me about 4.5 turns without the suppressor, to get it to cycle, eject, and lock back, then all was well. Then I attached the AAC 762 SDN and let me tell you it was ...

Finally got my AAC 762 SDN suppressor after an eleven-month wait, so I take it to the range to try on my (1) T/C Contender in 7.62x25 Tokarev; and (2) RARR in 300 BLK. Well I love the suppressor, very quiet with subs, pop-crack with supers. But the magazine latch on the RARR magazine fell off after...

Here's mine but to be honest I haven't shot it yet. Sorry for the double post.

Here's mine. To be honest, I haven't shot it yet, but I like the way it looks!

Thanks for all the good comments. I ordered today a slick side upper, no FA, from Aero Precision, as well as an AP 9" handguard, 10.5" barrel from TacFire (any experience with that brand?).
