If that's it, a 45 caliber 300gr bullet with 60gr powder - you're looking at 45-60 cartridge performance, or about 1400 feet per second.
Should work nicely if it shoots to the sights.
Thanks for the conversion factor. I should have looked it up, rather than attempting to remember.
My error - 14.5 multiplier is Bar to PSI, for example air guns with a max. tank pressure of 200bar, is 2,900psi.
Yes - that's about it, Tinker, similar to a .45/60. 1,400fps to 1,500fps would be about it.
