Here is picture of a lightweight Barnes bullet in 24ga FH.
Guys cut the back off of 750gr bullet off to get 500gr weight.

Here is picture 58 cal Minie slug that's little long on the side for our 12ga
sabot, with the front of the slug above the grooves swaged to fit in
sabot. The swaged front third of the slug fits next to the internal ridge in
sabot and the sabot doesn't bulge out.Just run front into a die
and punch it back out.

And some info about 12ga FH and other hopped up shotgun slug loads,
You know we like to use the rifle, IE slower than shotgun, powders.
We like to use IMR 4759 for some loads and RE17 for others where
we have room for larger charges. Those two powders are ignited ok in large
diameter cases like 12ga, 10ga, 16ga, etc, without needing BMG primers.
But we have always been looking for easy to ignite powders of the RE17
type, when cold, that has a speed between IMR 4759 and the RE17.
RE17 uses different process to put the deterrents in the powder to control
speeds, which allows much easier ignition, compared to big majority of rifle
powders with all the deterrent on the outside.

There are some out there made by Nitrochemie Switzerland, who makes
RE17, RE26, RE33, etc, for Alliant. It's the ' RELOAD SWISS' brand available
for those in UK and Europe, They are called RS 40, about same speed
as RE12, RS 50 & 52, same speed as RE15, RE60 & 62 same as RE17.
Also one ' Vihta Vouri ' powder called TR140 available over there,
that Nitrochemie made..

Many guys can't get IMR 4759 anymore, some can't get RE17.
I'd like to get some of RS 40-50-52 powders or V V TR140
into the states, would really be great help for hairy slug load work.
And guys in UK/EU now can load some real hairy, slow powder, slug loads,
even though not having IMR 4759....Ed
