Interesting site, thanks! Looks like 45ACP peaks at 16" but doesn't get a whole lot extra ummph over a 5" barrel in the heavier bullets.

The Marlin has an 18" barrel?

I'm wondering if anyone has chrono'd 230gr 45ACP from some carbine length barrels? The two data points I'm most interested in are at 16" and what length is at 1000fps or so.

In theory, I agree. However, I've never seen much in practice that is done like this. In fact, I'm not sure the reweld can always be re-heat treated to be like the original. The weld point is always the weak spot. I once completed a trade for one of these rewelded op rods. The welding was...

I think I have everything figured out. The previous owner had the port buffer notched in the top rear (looks milled) to not interfere with the scope mount. I'm guessing the end result is less rigid and the sides act like springs when hit by ejecting brass. The rifle actually throws brass half...

Hard to tell for sure, as I have run into batches of Wolf with especially hard primers. Changing to another box of Wolf fixed everything.

There is nothing non-proprietary or non-HK about the 16" gun. It just uses the front end from an HK93 which is the same as the G3K. Now, if you want to debate about which stuff is cheaper or more readily available, have at it.

While I have no personal experience shooting ammo others have reloaded, a coworker does. He purchased a rifle on consignment that came with some reloads from the previous owner. The first shot was hot and blew out a part on the gun (extractor I think). You just don't know the attention to...

Once upon a time, it seemed as if all the Glock retailers such as Glockmeister, TopGlock, etc. sold spare Glock slide assemblies and even just the frames. Now these parts seem to be absent from their sites. If I wanted to buy just a Glock 29 frame, is it even possible anymore?

I have no way of determining that, and bought the bullets I have second hand. I could go back to the manufacturer and check. I'm guessing you'd want me to push harder bullets faster? Let's pretend these are at the top of the cast hardness scale. (28-30 Brinell??) Well that would explain a...

After the initial slug was made and measured, I did indeed run it back from the chamber end just to feel out the barrel. It is indeed constricted at the end, and at a point or two in the middle. What is PSB? What is this actually doing? I've heard of fillers being used to take up case...

I guess I should have been more thorough, but the posts are going in a direction I did not anticipate. Here's where I am: I am sending 265gr, gas checked, hard cast bullets downrange at 1550fps per my chrono. At 25 yards off an improvised rest, my first two rounds are touching in the...

Just for reference, I don't hunt, so this isn't about terminal performance. I just don't see the need to have this rifle and load it to 44 magnum levels. ;) There are some newer theories on cast load development that revolve around loading for pressure. Most of the classic cast loads use...

I just slugged the bore on my Ruger #1 in 375 H&H. The answer is 0.376", but it was obvious from the feel that the last 2" of barrel near the muzzle is perceptibly tighter than the rest of the barrel. What can/should be done about this? I suppose I could fire lap with 0.376/0.377 bullets...

Yes, yards! Most people seem to be reporting 20-25 feet and that is about what my HK did. The locking lever is actually quite stiff on this and more so than I remember on my HK. I can check the geometry of the piece against a spare carrier I have. Good point. I certainly will send it...

While I don't think the rifle had been fired much at all, the recoil spring is probably surplus. It doesn't seem worn, but I suppose I could try another. I just don't think that 20 yards of ejection is anywhere near normal and certainly wasn't on the HK I had. It just gives the impression...

See the strap in front of the user that runs parallel to the rifle? That's what makes it a three point sling. i.e. An extra strap that covers the weapon controls, catches on your gear and functions as a general nuisance.

Beat me to it!

Keep in mind as you read this that until a year ago, I owned a real German HK91. I'm not a complete stranger to the platform. I took my new to me PTR91K (early AW06xx serial number) out to the desert yesterday. This thing cycles quite hard. Even with a port buffer, I was collecting brass...

I have recently started loading the 375H&H for a Ruger #1. My initial loads are 265gr casts using 32gr of RX7 per the manuals (check me!). I shoot these prone and it is not much worse than a pistol caliber carbine. I haven't chrono'd them yet, but I imagine they come in at 1500fps or so...
