Is it safe ?

The Lyman 454190, 45 Colt 250gr. in a tube magazine ?

The meplat looks awful small to stack them nose to primer.

Anyone with hands on or shooting experience with that combo'?

Are we talking the same boolit?

That picture of the boolit at the bottom right is similar but the meplat on the pic looks larger, it even looks larger than the pic of the mold. The ogive is not the same on the pics either.

The boolit I'm using has a much smaller meplat, it is about the same diameter as a large pistol primer, it must be from a earlier mold as that design was the original 45 Colt design for the SAA revolver.

I know that design wasn't intended to be loaded for a lever action and the rifles in 45 Colt caliber didn't come along until much later. That may be my problem.

I don't have that mold but I have a question.
Is the meplat larger than .220"? I suspect it is.

The picture (there's only one not two) is from Midway which sells the mold today so they should be the same.

In Lever action 45 colts I think 1985 was earliest factory offering but there were rifles offered in 45 colt before then - but as you can see from factory ammo pictures they had no problem chambering for factory RN ammo. I have heard of tubular magazine chain fires happening but to my recollection I have never heard of the soft shooting 45 colt having that issue.

if you can put a round nose 30-30 factory cartridge into the back of another , anything with a flat nose even half the surface area of the primer or of soft lead should be safe , factory hard cast round nose are fed into a tube every day in 38/357 lever guns they have no flat at all

The Peters look like the 454190, measured the LPP 0.210" the meplat on my 454190's @ 0.220" and I never took the round nose 30-30 into thought.

So with the help gained in this post I will probably try them in my Rossi with 8.5gr. Unique. :bigsmyl2:

I would consider them safe from a nose to primer in the tube scenario. My Lee 180's flatten 1/2 that much seating them in their cases. Just look at Federal IIRC 170, maybe 150s HPs, they are copper RNs with no lead ecksposed and a HP about the size of the thickness of a Qtip stick if that.
