12GA rifle From Hell--

[hubel458]

28GA FH research. Guy on forums suggested using 54cal
rifled barrels for 28ga as they are easy to get. I looked into
it and did some testing. It is ok as long as you keep bullet
about 400gr as most 54cal barrels are not super alloy.
You got to use the thick heavy ones also, being stronger.
And everyone with 28ga wants slugs and there is no slug loads
from factory, and to reload the heavier bullets we shouldn't use
these barrels or regular 28ga barrels with 600-700 gr slugs.
But there are couple dozen 54cal bullets out there
stocked all over the gunstore shelves, in weights from 300 to
450 gr. There are heavier but for 28GA FH on deer 400gr is
great. I tested the 405 gr copper plated Powerbelt brand, with
velocities from 2300 to 2800 plus fps. That's 6500 ft lbs.
The 54cal slugs load tight in the RMC 3.25" 28ga case fine by
sizing top a little tighter. Bullet obturates to fit .550 bore
as bullet is hitting target straight. A lot of 54cal barrels
go from 530 to 560. 54cal slugs range from .534 to .560"
There are different sizes of 28ga barrels and chokes,
so some where there is lighter 54cal slug that fits..
And with light slugs the pressure limits with the MRC brass
match top muzzle loading pressures, so these barrels will work.
And great thing is the 54cal barrel guys ain't allergic
to making long barrels. I've shot one MRC case 15 times and
still going strong...Ed
