The structural integrity of the projectile is definitely something I have to give consideration to. I can probably make some inert for testing by removing the guts, and replacing with equal weight of...

I understand the dangers here, but guys, what I'm doing is just making a black powder cannon. That it's a firework is, or should be irrelevant. Like any black powder firearm, it needs to not explode,...

They are 5" & 6" long cylinder shells that I buy. I don't make my own, but I was figuring on cutting the lift charge open to repackage a larger charge. I hadn't really settled on how to handle that...

That's an interesting idea, Super6. I especially like the idea of a wood bottom plug, for safety. You think HDPE pipe is strong enough? What kind of lifting charge do you use?

Winger Ed, you're...

So I buy these 60gram 5" mortars for the holidays. They come with fiberglass mortar tubes. The trouble is I'd like to fire these mortars higher. I'd like to get them twice as high, if possible, but...

Hey Lathesmith, could you make me a sizing die please? I sent you a PM.

TIA.

I've said my son won't fully appreciate this rifle till he's ready to teach his own children. Then. And that's the point, that the rifle is a symbol of a father's love and lessons that are to be...

Thanks for the kind words guys. I hope I live long enough and in good health enough to see my grandkids, or even great-grandkids learn to shoot with it. That would be an excellent treat.

As you...

My 8yo son's birthday present and his first gun (bottom, top one is mine.) I cut down a Ruger American Rimfire Talo edition 22lr to youth size. The barrel is 16.25" and threaded with a seamless...

You guys have it all wrong. Crocs are great for this because they allow the molten lead to flow through and out of the shoe unlike boots which would trap molten lead in next to the foot.

Kidding,...

I've got all those things. I do have my suspicions that the x-die works in a way that is counter productive to fine accuracy but I haven't tested it much yet.

Its a wylde chamber.

So I took a chamber cast of my AR barrel today. I bought the barrel new as a Wilson match grade barrel. Haven't shot it much yet. Its 20" stainless hbar style, 1:7 twist. Anyway, the one thing that...

I was told that oysters were only legal to harvest in months with an 'R', thus you just couldn't get them in the other months. Granted, that was 20+ years ago by my grandfather who may not have known...

My oldest is 4yo and we have this battle regularly. The rules are that he doesn't have to eat but he must eat the vegetable first before having the rest of the meal. This worked for a while till he...

Mind saying who? Or where to buy said punch?

Indeed. I especially like that a good non-corrosive primer can be made without ground glass. Just the idea of sending ground glass down the bore is like nails on chalkboard to me.

My ears were burning.

Is there a DIY smokeless powder thread yet?

I never said it was the best or even a good option. I merely presented a video of it actually being done in the real world by a real person "back yard" style. I wish we had this kind of video of all...

This was just posted on youtube. Now, keep in mind this guy isn't a "gun guy" really, he's a sciencey undergrad who's ambitious enough to try and fumble his way through all kinds of projects. This...

I think I did see a molybdenum disulfide powder coat at one point. Can't remember where.

Got a 2.5x-16x50 Bushnell. And I've got both Hornady 55gr fmjbt, and 77gr SMK. TAC, and H335. Lots of TAC so I'm hoping I can find "the" load with that. I'm shooting a 20" stainless Lothar Walthar...

I've got something like 1500 of '11, and another 1500 of '12 as my two biggest lots. That should give me plenty to work with.

I am interested in learning, testing, first hand whether there is any quantifiable difference in lot years. I'm betting not but I did sort the brass already. Took me all week but I did it.

Well, fortunately I've got enough brass and enough time to sort it and prep it in every possible way. I intend to debur flash holes, uniform primer pockets, neck turn, weight sort, and concentricity...
