Question about 300blk

Congrats on taking the plunge. David

Thanks, but I fear how deep the rabbit hole goes

Update.

My face is just as ugly as it was before shooting the resized bullets. They were decent as far as accuracy too, I was able to hit a military silhouette a few times at 300y with only a red dot sight.

Had an issue with another rifle though. Long story short, is it safe to knock a loaded round out of the chamber by the nose? I tried tapping it out with a cleaning rod, but it didn't budge. I just want to make sure it won't go off from hammering the bullet with a cleaning rod or whatever

[Happyguy]

As long as you are going from the bullet end and not the primer end you should be good. What caused it to stick? David

[Mbaker78]

Neck sized one too many times I guess. I couldn't originally get the bolt to close and as I went to extract it it pulled a very small piece of the rim. Subsequent attempts to get the extractor to pull it out must've driven it in tighter...

I got it out, took more force than I liked, but it's out now. I just have to put the rifle back together...

Have you tried them bullets I swapped you yet?

[DukeInFlorida]

Neck sizing is ONLY one part of the equation.

You MUST trim the brass to length after full length sizing. If you don't trim it, the brass becomes so long it gets wedged between the bullet and the beginning of the rifling, creating a blockage. If you fire that round, which would usually chamber with some effort, you will likely pull the end of the neck off the brass.

Bottom line, full length resize first (properly, the shoulder must be set to where it's supposed to be), and then trim the brass to length.

[Mbaker78]

All of my rifle brass gets measured at the very least, anything over max length gets trimmed, even after just neck sizing.

Haven't had a chance to try the bullets I got from you yet. I'm about to start a 7 day work week (12hour shifts) so it'll be a little bit yet. Is it safe to tumble pulled tracers in walnut media?

Can't see why not, except it would probably kill any chance for it to light off........which could be a GOOD thing.

[Mbaker78]

Yeah, I'm not exactly sure where I can shoot them around here either... Maybe this winter when there's a foot of snow...

Hmmmm. If you've been neck sizing only you know they say about every fifth reload they should still be full length resized. I bet the shoulder was creeping forward.

[Mbaker78]

That's my guess. Not sure if I mentioned that it's federal brass... I guess it's notorious for being excessively soft...

[Mbaker78]

Kindof along the same lines as the OP, has anyone tried sizing down .32cal pistol bullets (100gr gold dot, for example) and shooting them in a rifle?

My main questions about this are whether they would feed and if they would even hold up to the velocities (~2150fps) or if they would just shatter upon leaving the barrel... I'd imagine they'd be pretty explosive if they managed to stay intact and hit a target.

Cast and sized the Lee TL314-90 SWC down to .311 but haven't loaded them yet. Doubt they would stand up to those velocities as they were made out of 50/50 COWW/lead.

I have done 32 Mag bullets down to 308 to try in a 30 carbine. David

I have two chamber adapters for my Mosin Nagants. One lets me fire .32 sized bullets (.32 ACP, .32 S&W Long, and .32 HR magnum), and the other one lets me fire 7.62X25 pistol bullets. Sort of like firing a .22 rifle on that big old heavy Mosin.

[Mbaker78]

I've seen those adapters, thought about getting one for 308 to 32acp

[gandog56]

Ummmm, bad idea? A .32 ACP is sized to .3125".

[Mbaker78]

Yeah, I'd wondered about that.

[gandog56]

Just run them through your tumbler, that will remove the sizing gunk.
