Can Hi-Tek coated boolits be used in BP cartridges?

[Gray Fox]

I just got some 350 grain .458 Hi-Tek coated boolits from Acme Bullets. Would these shoot OK in .45-70 over holy black or Pyrodex Cartridge Grade if I pan lube them in Lyman black Powder Gold? GF

Only one way to find out

You’ve lost lube grooves to the powder coating. As such, you may want to add a lube cookie to make up the difference

[Gray Fox]

This one still has two lube grooves and a crimp groove, so I guess I'll get out my pan lube kit and give it a try. I've got a Browning 1885 and an Italian Sharps '74 repro to try it in. If all else fails, I could add a card wad and grease cookie. GF

The powder has not taken up enough space in the lube grove to make a difference.
