If shipping wasn't so expensive I could send you one to try but it would be costly for postage round trip.

Holy crap! yes! they are good guns... They basically are an MK with a reshaped reciever and the longer barrel. Come with the larger 11/16" breech plug...

Still a White guy would tell you thay are the best for conicals...

Actually Ron it is basically the same barrel as your GM-LRH - shoot you probably already no that...

One other BIG point for shooting the longer conicals... the 52's are a 1-26 twist - that raised your eyebrows didn't it?

They shoot a 535 gr conical with great accuracy. I never really experimented much so I don't know what other loads would work well as far as conicals. With 100 gr of powder it has quite the wallop , that I do know

Oh now you done went too far! I got to do some thinking.
Instead of shipping rifles. I need to find a mould to borrow and paper patch some bullets. Then one of you guys could do the shooting. It has me thinking. Ron

Who makes the conicals? Ron

I don't know who makes the mold but a guy on one of the auction sites sells 52cal conicals in 3? weights.

Hey Ron, here's what I could find:

Lee makes a 515-450 and a 515-500
Both nice looking slugs!

RCBS makes a .520 #82170

Lyman makes (or made) a 515-139, 515-141 and 515-142

Plus a 518-145

I'm also interested in this topic. Really liking the Knight 10% discount on their 52s but I would want a mould to cast my own full sizes in case the supply dries up (plus it's just plain fun to diy)

btw: this topic finally forced me to member up here!

Here's the 515-500

First. Welcome Duffer!

Nothing wrong with lurking around. I do it many places. I have messed around with these in my 52. I bought them off a guy on gunbroker who has them always listed.

These are 370"s and 430's I believe. They shot well but I haven't had time to mess with load development, etc.

This picture is a couple I ran through to see how they were catching the rifling. I was wrapping with teflon tape.

Ron I sent Sharpshooter a mold when I sent the 52... Ask him what kinda mold it might be... Actually SS you might send the mold to hime to check it out - unless you might cast some...
