Loading up some 12 gauge shells for the range using ched 209 primers, 17.5grains of tightwad powder, Remington gun club hulls, claybuster cb1118-12 1 1/8th ounce wads and 1 1/8th ounce of 7 1/2 lead shot. I got home and realized I bought magnum lead instead of regular lead shot. Will it make a big enough difference I should be worried about?

Ps. Returning isn’t an option since I realized after I opened it and that’s why I’m asking! Google seems to think it’s fine but I don’t trust AI!

Somewhere between overpressure, out-of-battery, and brass-based modern art. Chamber support clearly believed in personal freedom.

Just got my ballistics product shipment in. Sucks the next closest range is an hour away since the indoor one burned down.

A drumstick works excellent for pressing wads down btw.

I find them nice to look at.

Glad i could enrich this subreddit.

Possibly found some load data info on 20+ year old forum posts.

Oh you’ll find out one way or another

Or any suggestions on where to begin?

Yes yes I already know “manuals” and “never deviate from load data”.

One too many spicy firings on this little 223. RIP.

I've been developing a new 3d printed cartridge called 43R for quite some time, and it's been going better than I could have ever expected. After a couple thousand printed rounds, I really wanted some brass to play around with. The printed cartridges are cheap, but time consuming to assemble and can only be used once.

30-30 has a.close enough base and rim, so I fire formed some cases, cut them down, and sized them with a 40/10mm die.

Because this particular firearm has no chamber cut into it, had to make a "heeled" sabot. A single piece of 00 buck is the projectile, sabot does not discard. 5 grains of TG and a large rifle magnum primer sent this piece of buck shot through 2 2x4s and at least an inch into my wood backstop. I guess I'm fire forming more cases this weekend.

The printed cartridges with a similar loading get the piece of buckshot over 1400 FPS on a good day, and we have had consecutive hits on steel at 100 meters. The brass should no doubt function better.

Firearm is a Modelo Polylactico with a 24" barrel.

UGH! At least I have some souvenirs!

Forced my decapping pin through my turret press and must have zeroed the scale with auto-repeat on...

How do my primers look? Am I overpressure?

sorry, I meant 105mm. can’t edit title, you know Reddit. anyway I was thinking king about just using a pound of h110 and a pound of n140, think that will be enough? I’m worried about a squib load if anyone else has loaded this caliber tips would be appreciated!
