Ile Bizard P.Q.
I have read on a thread someone pushing PC cast bullet in the 1750 fps without gas check and no leading

I would like to know from casters their experience in this field of shooting non gas check bullet and powder coated
up to what velocity they have reach without leading



thank you
 
As reported earlier, I have a mould that throws a PB bullet with no grease grooves, for powder coating.
I have put eight out of ten rounds into 1 and 3/4 inch at fifty yards with a measured m/v of 2424 f/s average.
This was in a Sharps .30/30 .
It seems safe to assume that when you're pushing the performance limits, bullet quality and selection becomes even more important.
I'll be working on things further in the spring.
PS. The bore stayed bright and shiny.

before I did not want to hear about PC but the more I read about it my interest is growing

eager to se your results this spring
would love to shoot my PB 500gr in my Sako brown bear 450 Rigby at around 1700 to 1800 fps
 
Powder coating my cast 9mm BHN 8-10 bullets solved my leading problem. The bonus is that with PC bullets there is no metal on metal contact, abrasion, or lead vaporization. Plus there is less smoke too.

Powder coat is incredibly tough & I have recovered many bullets showing that the coating does not come off.
My next project is powder coating cast LEE 340 grain round nose bullets for the 45-70.
 
It will have less wear. It is similar to a plastic and is most certainly softer than a gilded jacketed bullet.
The only possible caveat to this might be a matte PC coating. Matte PC would very likely increase the friction coefficient over gloss PC but the only way it would create wear is if the PC coating actually contained an abrasive component and while such a thing might exist I'm hard pressed to figure out what purpose it would serve. Otherwise I can't see any PC being as hard or harder than barrel steel, therefore minimal to no wear on the barrel.
 
I'm a fan of gas-checking my powdercoated bullets.

In theory, the pressure of the gas check on the rear of the lead bullet will mushroom the base and push the gas check outward to seal the bore. This helps prevents blow-by and powdercoating burn. Further, the forward scraping action of the gas check cleans the barrel on the way out.

I have never had a cleaner barrel on my big bore Jeffery. I'm pushing bullets past 2000fps with 2" groups at 100 yards. I'm looking to reach 2300fps. Proper barrel finishing and bullet sizing is key. Luckily my Blaser barrel is finished like a mirror.
