458 Lott 720gr cast

Thanks for your time and help Burnt. I will try this in baby steps for sure, that's alot of gun but is a falling block ruger #1 so that makes me feel a little better. I'll post again when I figure it out.

The bullets were turned on a lathe as far as I can tell. I only have 40 of them and picked them up at a Edmonton Gun show this year for $12.

The pic is of a cast lead bullet. It wasn't turned on a lathe. Any shiny surface is from when it was lubed and sized using a tool like the RCBS Lube-a-Matic. The copper bottom is a "gas check" it is press fit on the shank of the bullet during the sizng/lubing process. It is designed to protect the base of the bullet from the hot gases created by the discharge of the powder load. This prevents "gas cutting" of the cast lead alloy a thus helps protect your barrel from building up deposits of lead which wil negatively impact accuracy if you allow it to build up. "Leading" is a pain in the butt to remove. That is why we use gas checks and good bullet lube.

If you plan on firing many of those out of a #1 Ruger, I would suggest you get yourself a PAST or sissy bag and fire from the standing position and not from the bench or prone.
 
I'm sure you'd be safe with a case full of Goex Fg (that's blackpowder if you are not a fellow devotee) :D

I shoot 700gr bullets out of a .50-140 Sharps and although I'll never shoot smokeless in it, I have seen loads using H4831 so the previous posters may be on track.

I will also concur that heavy bullets like that coming out of a light gun like a Ruger #1 will be painful. Especially if you get more than 1400fps or so out of them :D. My rifle weighs about 12-13 lbs and I don't shoot too many rounds at a sitting.

Take this "advice" with a large grain of salt. Instead of relying on so-called Internet "experts," go pick up the Lyman Cast Bullet handbook. It should answer almost all of your questions.
 
myself , i'd keep ANY bullet away from the lands , until i had a couple of decent loads worked out pressure wise ......
the less variables the better .
seating the bullet into the lands will cause initial presures to be higher than not seating the bullet into the lands .

Wow - people get banned for saying this? :p

The 458 Win Mag can be a great cast cartidge, as can any.

On the other hand, I have found that most of my cast loads work best when they engage the rifling on chambering, but to say that's a universal truth is something I can't support.
