What about machining like a pistol dovetail and then making an adapter to slide into that to then convert it to a rail for mounting? I measured the wall thickness of this pipe, and it's 0.200". How...

Sure, but would still need 2 normal points to hold it in place towards the axis of the bore, and then WHERE is it safe to drill reliefs for those non-threaded studs?

What if a tight tolerance non-threaded stud were put between the screws?

Well again, this has been shortened to a barrel length of 18 5/8 in, so quite a lot lighter

Anyone put a red dot on one of these single shots? Where did you decide was safe to drill / tap? Or did you affix a rail by some other means?

Thanks!

Yea, the russian one even uses the same pictures.

Link?

Just wondering, but wouldn't .0025" interference on both sides be too much?

What would you ask for it?

Took some [quality] dial calipers to it, appears to be .775"

So I recently procured a NEF 10ga that I had cut down to NFA legal (18.625", aka "Thumper"). Obviously this has no choke and is full cylinder bore. I would LOVE to find a mold to cast some good hard...

I asked RotoMetals what they do, and they said they blast and high temp paint theirs. I wonder if there's any reason why Cerakote (esp the super high temp exhaust ones) wouldn't work....?

Well they're already oxidizing so I will likely need to blast them, but yes I should probably oil them. I would rather have a more permanent long term solution though.

So I have a couple bottom pour ladles that are a few years old, and have developed some surface oxidation. When I try to pour with them, they create more dross in my molten alloy and it's becoming a...

True enough.

Well, brought out my lyman on a hunch and they have rifle data for a 16" barrel. Best group with 255 SWC's was with 6.2 grs of titegroup over a winchester large pistol primer, rocking 1009 fps. Seems...

Why does hodgdon cartridge loads have .357 rifle data but not .45 colt? :(

Also, I would think that if I aim for a flat 1000fps (since the speed of sound is around 1115fps on a "normal" day), I should be pretty safe. I have a chronograph (competition products prochrono) so...

Would it be a good idea to use a wadding to get consistent powder location in the case for this type of control?

Winchester 92 carbine levergun. 16" barrel length

What kind of chonograph data did you get from that load? According to my load data book (lyman 49th) that load should be only coming out near 800fps....

So I dropped some of these bullets in water to quench harden them (they're a normal hard ball antimonius lead), and I'm wondering what kind of powder and charge weight to run under them to get them...

Just wondering, how strong are the chambers of those rifles in comparison to say, an 1895 guide gun? Can they handle stupid hot stuff?

I just use Lemishine per the SS tumbling media solution.

Thank you. I'll keep those in mind as well. Need to burn through those powders.

Already have a guide gun, but thanks!
