Winchester ball. I guess it was 50 grain. These were not results I expected but, nontheless, don't enhance my confidence in the round.

Ya got access and skills to run a lathe? That's the only way to do the job right. Chuck up the barrel and get the muzzle end running true with an indicator. Turn the muzzle down to 0.500" and cut threads at 1/2 - 28. Granted, $100 is too steep for this job. Gunsmith must have some "insurance"...

Sorry, in my universe the pellet rifle penetrated the 1" board. The 25 ACP did not. Both fired at about 3' from the board. Please note well: I'm not saying a .22 pellet has more energy than the 25 ACP, but out of my two weapons, it indisputedly has more penetration.

Sorry to all the .25 ACP defenders, but personally, I'd take a .22 LR any day, and for certain a .22 WMR. I've done penetration tests with .25 ACP hardball on a 1" pine board. It won't at point blank range fired out of a Baby Browning - just they type of pistol people have been talking about...

RRA has done a nice job with both selection, and quality build. Try RB Precision or ADCO for your needs. RB Precision has the entire RRA catalog on their web site. One hint: you can buy an RRA lower and an RRA upper for less than you can buy the entire gun. Just assemble the upper to the lower...

LMAO!! IMI ammo ain't Kosher enough for the Islamic terrorists? Speaking of terrorists and beheadings, the best one I heard put forth on this is to light off a small tactical nuke about 80 miles outside of Meca on the first beheading. On the second beheading the size of the nuke doubles and...

LOL!! Duh...is there a less risky approach? Guns in DC? You gotta be kiddin!! Actually, is there some way to exploit ATF paperwork to "prove" the gun is legal-stegal? Something along the lines Mulliga suggested? I don't know too much detail about ATF procedures or forms.

Before I started this thread I had given some thought to the dated-camera approach along with mailing a sealed, certified envelope to myself with the appropriate date stamps. I see three problems with this approach standing up in a court of law. First, with every tom, dick, and harry capable...

And therein lies the crux of my assumption that the same scenario happens with a sunset of the current AWB, and then an extension takes place at a later time. One will have to physically modify their weapon during the "legal" period between bans, and then somehow prove that the modification(s)...

Lot's of engineers out there have an MBA as well. I don't think you can necessarily make such a leap to a conclusion.

Let's assume the AWB sunsets in September. Let's assume I have a post-ban AR-15, and that I'd like to add more than two of the evil features - namely a flash hider and a collapsible stock. Let's say I do this, come Sept. 15th. Now let's say that the AWB is reinstated, some months after I get...

The Trijicon ACOG is the TA-11F with the chevron reticle and the extra eye relief. Front iron site is GG&G, and the rear BUIS is the ARMS #40. Front rail is the light weight Yankee Hill Machine forearm. Upper is the RRA 16" varmint barrel, and lower is RRA with the 2-stage NM trigger. At the...

Here's a second on the Rock River Arms recommendation. You can go to RB Precision or ADCO and get some great deals. It turns out if you buy a completely built upper and completely built lower you can get both of them for about $75 less than a completed rifle. And, of course, just insert the two...

This is a RRA 16" upper on an RRA lower that was finished with the Brownells Teflon Moly Oven Cure finish. The barrel, and Yankee Hill Machine quad-rail were both coated. I won't say that I'm satisfied as it does not seem to be a very scratch-resistant finish, however. Zirc

Like DoubleAction said, why limit yourself to one or the other? Many pistols can be converted with a simple barrel swap. I do believe the .357 Sig is a bit more accurate, even within 50 feet. Not much difference in recoil between the two rounds IMHO.

Yes, all the usual suspects apply for finished attributes of the steel. Chemical composition is very important for hardness, strength, and toughness, as is the heat treating recipe. I honestly have no idea what composition Kimber or others specify for their metal powders. At one time on the 1911...

Master Blaster, I think maybe you're taking the density term out of context. Density is in fact a critical attribute for MIM and cast parts. It's true you can't compare a part made of lead (with high density) with a part made from titanium (relatively low density) and assume that the lead part...

7.62, Thanks for the welcome. No quibble from me. I do have a Kimber, and I replaced the slide stop with a billet steel part, even though the original MIM piece did not fail. I think the stop is one of the more heavily loaded parts based on function and crossectional area. Parts like the...

The flaws in MIM are typically small voids (air pockets, if you will.) The longevity of the part depends on the size of the flaw. If the voids are very small they will do no practical harm during the lifetime of the part. The larger the voids are, the more deleterious. If they are very large...

Well, I've got both the vest and the pants, and they have more pockets than I can figure out what to do with. Royal Robins is missing out in not providing the new owner with a set of "suggested" uses (pictorial) for the pockets. It will take me the rest of this century to figure out an optimal...
