I just ordered a case of 38 caliber 125 grain round nose from Blue Bullets. I plan to load them in 38 Special and 357 Magnum cases. Original load was the Missouri Bullet 125 Grain TCFP, 3.5 grains of Clays powder. Chrono'd from a 4" Ruger GP100 at ~950fps (no significant velocity difference between 38 and 357 cases). When the Clays powder ran out, I switched to Ramshot Competition, which I found produces the same velocity for the same charge weight, and it meters better than Clays. Will have to see what happens when I substitute the Blue Bullet into the load.

I bought a Burris TAC30 1-4x24 and P.E.P.R. mount from Midway for an AR upper that hasn't come in yet. In the mean time, I've been playing with the scope by itself, and I noticed that the reticle size does not change with the magnification power. This mean that the ranging dots and distances subtend different MOA values at different magnifications. Maybe this could use some explanation. Check out this image of the reticle from Burris: Notice that the center dot is labeled: 2/3 mil (2.4" @ 100 yds) So is this specification true at 1X, 2X, 3X, or 4X? Since the reticle doesn't change size with the magnification, it can't be true for all magnifications. It can only be true for just one magnification, for example: If at 1X magnification the center dot subtends 2.4" @ 100 yds, then when switching to 4X magnification, the dot stays the same apparent size in your field of view while the viewing image gets 4X bigger, so the center dot would subtend only 0.6" @ 100 yds. Or if it's at 4X magnification that the center dot subtends 2.4" @ 100 yds, then when switching to 1X magnification the dot again stays the same apparent size in your field of view, while the viewing image shrinks by 4X, so the the dot now subtends 9.6" @ 100 yds. So at which magnification are the ranging dots designed to be used? 4X makes sense to me, but I'm not sure. I could probably find this out for myself by putting objects of known size, like a 1" grid or ruler at a known distance, like 100 yds, and seeing at which magnification do all the specified measurements match up to what I'm seeing. However, I would feel kind of stupid taking just the unmounted scope to the range since I don't have the rifle yet. Someone just tell me!

I have a made-in-Germany P226 9mm, frame with no rail, roll-pinned breech block, etc. and I could not tell that the slide was a stamped part. They say the front flange is welded on, and I must say that was a damn-good job then, because I could not see the weld bead, inside or out. Even if the slide started as flat sheet stock, and the gross shape was formed by a stamping press, they must have machined the slide rails, ejection port, sight dovetails, slide serrations, barrel and recoil rod holes in multiple-fixture operations. 3, 4, and 5-axis CNC machining centers weren't readily available back then, right?

I read this on the shotgunworld forum: Loading Lyman 525 gr. slugs for the H&R Ultra 12 gauge Perhaps the low recoil load is is marginally above 1100 fps, causing it to tumble sooner than the higher velocity load.
