Thread: Subsonic action

If you powder coat your cast bullets you will get no leading

Leading occurs when 1/ you forget to lube your bullets or 2/ when you push them too fast and friction softens the lead leaving streaks in the bore and sending accuracy to buggery. It comes out easily but needs a bronze brush and light oil to get it out.
Hope that helps.

Excellent. Thanks.

I won't even ask how that is done. Baby steps.

A related question...
How do you know when you get leading? Is it easy to see down the bore (like carbon) or at the muzzle (like copper)?

What powder and weight are you using for 1600fps in the .308?

Was using 17grs of AR2207 @The bomb

If heavy leading, loss of rifling grooves, looks more smoothborish.

If very heavy leading, it becomes a heavy barrel... (-;

Ok. So to get this straight in my own head.....If I buy cast lead projectiles they will be coated in wax? If I shoot them subsonic, I can clean out powder residue (with a carbon remover) and there should be no lead fouling. If there is lead fouling it must be scrubbed out mechanically (perhaps with a neutral lubricant) as opposed to using a chemical solvent? (like you would with copper).

I just use Hoppes No9 solvent and occasionally JB Paste, My .357 mag S&W 586 has had over 70.000 cast bullets through it and has never had a bronze brush down the barrel,
only ever cleaned it with No 9 and patches,Reasons your barrel fouls 1 it has copper fouling, it rips lead from bullet, 2 twist is too fast over spins the bullet, rips lead from the bullet, 3 Velocity is too high same as no 2
As in the black powder days want/need more power go to bigger diameter heavier bullet, The 50 cal BP with 500 grain cast bullets and around 100 grains of powder will kill any animal on the planet.

Took the 18” Tikka T3 out today for a subsonics run. In all honesty I prefer shooting the Browning BLR, simply for the silly cowboy factor. But seriously, with a DPT suppressor this rig is deadly with subs. I can shoot 3 or 4 goats, and turn around and go 250m over there for the next bunch that haven’t been spooked by full-power ammo.

It was a day of two halves. Goats immediately, then nothing for 5 hours, then goats at the end of the day. Stalked into a big fat red spiker, handsome animal, bang on deer o’clock on the walk out. I know a story is automatically “tall” without photos, but oh well at least I was there. I had him lined up and ready to go but just wasn’t happy with the amount of spindly manuka I had to shoot through. All of 30 yards. Suddenly he spooked in a massive rush of fright... and I was kinda glad. Weird how you put so much effort into something, then change your mind at the last moment.

No changing the mind when it comes to the goaty pestilence...
