Best subsonic caliber?

[Kind of Blued]

You mean like this?

Bingo!

Do you get a little less gas-in-the-face or are pressures about the same as .223? Looks like you have a gasbuster anyway.

I'll be checkin' out the 300W forum. This looks like fun, and one could get a heck of a lot more utility out of something like that than a 9mm AR.

Have you looked into the 6.5mm Whisper? I know you're a fan of those high BC 6.5s.

I cast round nose bullets for the 458 socom, 510/338/300 whispers. They are a bit less accurate than jacketed bullets, but much cheaper.

Which mold are you using? I have a 300W TC I use for silhouettes, and I want to mess around with subsonics a bit.

Thanks

My vote...

The three variables I'm trying to weigh are...
1) quietness
2) effectiveness on a live target
3) range

.45-70, 535-550gr cast or swaged bullet, case full of BP or a Trapdoor smokeless load.

Works fine for me out to the 1000 yards on silhouette, and does quite a number on the 400 yard whitetails.

+1 Talking my language.

Gewehr98 is using cast bullets, that's something I'd forgot to mention about the Taurus Thunderbolt pump that I'll be using, no gas port to clog up. With my long 26" barrel I'm pretty sure that I'll be able to get a cast bullet like Lymans .45 cal 385 or 405 gr to just subsonic velocity. Even the lower BC 385 gr bullet is only down 4" at 200 yards to the 240 gr .308 SMK. Nice thing about cast bullets is the hardness can be from non-expanding for large game to very soft pure lead and the nose can even be drilled with a hollowpoint tool if even more expansion is wanted for coyotes etc.
