should you see every land cut ?
« on: October 12, 2020, 06:03:25 AM »
my daystate fired straight down into bucket of water produces a pellet with perfectly even land cuts all the way around both the head and skirt of pellet, shoots great too.
my beeman chief shows nice even land cuts all the way around the skirt and some faint cuts on head, shoots very good.
hatsan bt65 carnivore 35 cal shows worn off ring around head and skirt with about 3 faint land cuts on skirt and none on head.

all of this is shooting down into water.
makes me think the hatsan isnt spinning the pellet and its just grinding off a ring front and back as pellet goes straight over the lands.

have any of you looked at fired pellets and if so what do you think about what i tried to describe ?
thx & best to you all.

All barrels are different, even ones which should be exactly the same. And, pellet diameters (skirt and head) vary a lot, especially between brand and even lots.

Th best way to tell, is slug the rifling, and measure the land and groove diameters. Then compare those with the pellets.

The .357 barrel could be badly leaded up also, might be good to clean it with a bronze bore brush and lead cleaning solvent.  Hopps #9?   Regards, Tom

Big Bores, shooting pure lead pellets or slugs seem to lead up pretty easily. I clean using a patch and goo gone, and if that doesn't remove the leading, then I'll use bronze brushes, and JB non-embedding bore cleaning compound. I then lube the barrel, and all bullets and pellets to greatly reduce leading. Bullets get 10 weight pure silicone oil lubing.

Every 12 is a lot.  Try a harder pellet or slow it down.  At required cleaning every 12 i would leave it in the safe and thats not good.

Research polishing the bore of the barrel.  Look at several sources.  Regards, Tom

This precisely why I have run Non Embedding Bore cleaner /polish through my big bores. Some the barrels, including the Texan were rough.

After polishing and cleaning I run a patch of M-Pro-7 to lube the barrel. I lube bullets, powder coated or not with 10 weight silicone oil.

I shot a bunch of  non-lubricated .457 round balls on Sunday, and boy did they foul the 909s barrel. Nope, not again.

thx folks, im not going to slow it down its under 800 now. the only reason i havent jb'd the bore is fear of ruining o rings, i think i read that its likely the o rings will be damaged doing so, i dont know how to fix gun so it stops eating them if it does. pumping this gun is bordering on too much trouble for me to shoot as much as i do with my 22's anyway. its hatsan bt65 carnivore 35 .
if i was confident of not messing up anything id smooth out the bore though,jb has worked great on lots of firearm barrels but i could just remove bolt and do it  , maybe i can remove some stuff and polish it without removing barrel , is that possible ?

I size my pellets and slugs to better match my bores.  I also hit all bores with JB.  It makes them really smooth and they almost feel like they have lube on them afterwards when cleaned up.  I put some JB on the OD of my FX liners is where I got that from.  After that, I follow up with hard floor wax (Trewax) inside the bores and let it dry.  I have a lot less lead fouling by doing these things and the guns shoot much better much longer between cleanings.  I use the Patchworm kit, the best I have found to get them  very clean.  I'll use a Dewey rod and a bronze brush if I need to, or just as an annual thing.

I forgot to add that I use 10 weight silicon shock oil to lube projectiles, but not so much as to have varying results, or to clog my LDC up.

I have yet to try the polish.  I would assume just a finer grit.
