When life gives you cracked necks on 338 LM brass, make a 510 whisper! What can you guys tell me about this round? looks like it might be fun with APIT ammo.

holy shit, I had never heard of this round but just read up on it. Sounds like 300BO on steroids. I was reading about people using up to like 975gn bullets at 1000FPS! I feel like that would put quite a hurting on some hogs or as a close range hunting rifle. Sounds like it suppresses well, too.

I read up on the case prep needed and that sounds like a real PIA. oh well, when I become crotchety and just spend all winter in my shop I will put this on as a project.

Isn't suppressed .45ACP loader than 9x19 because of more gas escaping quicker from the larger hole (given equivalent loadings and suppressor designs)?  I would think the same would apply here, and the .300BLK would still be quieter, all else being equal.

That's a caliber I haven't heard mentioned since I was a teen, reading gun rags. I didn't even know it was still a thing.

I looked into the 50 Thumper (similar to 510 whisper) a while back. They posted a video comparing it to unsuppressed .22lr and they were similar.

Nice.
I'm waiting for his video of "a single shot suppressed 45-70 is more quiet than a full auto suppressed beltfed 300blk m249".
