Subsonic loads for .223 and .260?

[Great-Kazoo]

Right... I have concerns about running them out of my 24" barrels without putting a ton of lube down the barrel first.

Sent from my teepee using smoke signals.

NEVER LUBE a bbl. You create restrictions , that may cause a nasty / expensive OOPS. Even to yourself.

Right.... you lube the bullet. I read some dude talking about how he sticks his in crisco.

I hadn't considered barrel length and bullets getting stuck. I guess that's why .300 Blackout barrels are mostly (if not all) 16". My .260 bolt gun has a 27" barrel. Maybe that rules it out as a candidate? The .223 load is for an AR with an 18" White Oak barrel. I don't care if it doesn't cycle the action.

I can shoot one of those red box colibri primer only 22's out of anything up to 16" . Anything longer and it's bust out the wooden dowel. Outside of the bolt action, who owns 16" AR's ??

55gr. Hornady FMJ
2.200"
Trail boss 4.0 1074

Some research on the Hide makes it appear I could find a load for the .260 using trailboss. Others are making it work. Time to go powder shopping.

when you find some (any powder) pm me. Always willing to save on hazmat.

I have my Trailboss. I'd like to start with the .260 load. Initially, I was going to use my usual 142 SMK, but they are unobtanium right now and I don't want to cut into my remaining 4 month supply for this silly project.

Are there any lead bullets in 6.5mm? I know exactly nothing about lead rifle bullets. Would they even make sense to try? They might come lubed already, and I'd guess barrel wear would be reduced, too. If that makes no sense, I may try the Lapua 139 Scenar since they are available.

I have a crazy desire to shoot a PD match subsonic. Dumb, I know, but it sounds like fun.

After yesterdays wind... I want a bullet moving at light speed.

Chris is local and might be able to help you out. He has been great to deal with so far. I know he is prototyping for certain rifle rounds.
We can always make a mold if it works out too.

I have a guy casting me some hard cast 223's in a 53gr. Those should not be loaded over 3000fps. which i can load light with standard powder or maintain the 1K fps with TG.

Jim, are they pointy or round nose? I think I understand round nose to be more accurate subsonic.
