?? I guess I don't understand the comment. If you are sizing to .454 and it will chamber you should be fine. As long as all the transformations on the way to the end of the barrel stay the same or get smaller in diameter. I was of the impression for a long time that harder was better. My 625 jm just threw me a fit. I messed with it till I was ready to send it down the road or throw $ at it till I fixed it. I finally went to air cooled WW and my accura y and slight leading went away. No other changes. I did check the hardness but it has been long enough I forget what it was. Soft by most standards. I think the hard ones were skidding into the shallow S&W grooves? Turned around on a gp100 and a fickle 19 smith and did the same air cool bullet. The 19 shot better to a point , basically a plinking/be speed which was ok with me. The Ruger did better but had to go larger in size. Then it caused loading issues in two cylinders. The Ruger was a borrowed gun so didn't fix it but made him aware of the issue. One thing on alox a buddy of mine has done for years. Let them set with a fan on them over night. If there still sticky just dust them with a little corn starch. He calls them his gravy bullets. Some folks use mica to acomplish the same thing. FWFL is not really a hard lube and is all natural no petro distillates. It can be used as a bp lube but needs to be a little softer which is easy enough to do. A lot of the commercial cast bullets lube is not much better than crayon. It is just to hard and has a pretty color to sell. They are made to sell if they shoot consider ones self luck anything past a casual load. Another thing is the bevel bad design. Just a bad idea IMHO. Saved a step for some but creates problems down the road on a lot of occasions. Jeff

This is just a thought/idea as it seems there is a decent size following of 32-20 folks here. I am not a fan of a shouldered cartridges in a revolter. But this seems a doable alternative for a lever gun/ revolver combo. This was after pricing 32-20 rifles and then asking how they shot and their glitches. A marlin 357 rebarreled and chambered to 30-357. Seems to me there would be little if any issues to feeding? No mods to bolt or elevator etc. Revolter just go to a 30 carbine and your done pretty quick. Brass is easy to find. Dies. Easy enough also. All this is is a 30 x221/300 blackout rimmed. 357 max brass trimmed back a bit and then leave a longer neck would also may be an option. A .312 barrel is sure an option but there is a heck of a lot more selection in .308. Y'all are a bad influence. Got visions. Get a 30" octagon blank, lop off what you want for your wheel gun. Heck ya could even build a pair of revolters and still have enough for a carbine. Color case hardened frame antiqued color for barrel buffalo or dark grips. Jeff

It is all about fit. Using cast think of it as shooting a shotgun, you want some choke. At any point in time the bullet leaves that case and any of the places it makes contact gets larger accuracy will suffer. Example as sized and lubed at 359, hits the cylinder at 359 then to barrel throat at 360-61 then to 358 in the groove then 363 at the muzzle. It ain't gonna shoot. Slug up? Some from initial kick in the rear coming out of the case. But once it hits the barrel and gases are going around it your done. Lube If you can cast good to excellent CB's you can make lube. Folks say it is messy or hard to do. It is no harder than casting. It is way cleaner than casting. I make and use FWFL Felix's world famous lube+carnauba using the original recipe. Does it work ? My test platform is a few rifles and pistols with proven cb bullets. One particular 30-06 is pushed to 2900 fps. Handguns are run to max jacketed speeds. Once again it is size. You can take a wrong sized bullet or flawed one and use lbt or spg or any high priced lube and still get crap. You use jacketed in the magnums, why?? Cast will shoot as good as jacketed in a straight walled cartridge. I am by far no expert on the subject. My cast consumption compared to jacketed for several years was around 50-1. Still the only jacketed I shoot are long range hunting cartridges and sub 30 cals that I like to speed up over 2750-2800. I don't own a set yet and ought to be kicked in the head for it. But, anyone loading cb s should own or have at their disposal a set of pin gauges. Especially a revolter. Jeff

I don't think the case is big enough to get any gain from the mp300. Or another angle mp300 is to slow. Is there data for 357 magnum using mp300? If no I would guess the above would apply. If yes you could figure a percentage. The only advantage I could see mp300 in the 32-20 would be to keep my speed up and pressures down. Not that I am having or seeing pressure in my buckeye now. I am shooting a custom design 140 plain base using a compressed load of 296/h110 with no pressure signs or issues. Speed is 1550 fps over chronograph. Jeff

Rim diameter is what I was referring to my bad. The 225 is what a lot of the SSK wild ate are based on. The few jdj cartridges I have tinkered with case life was exceptional. More Things for me to ponder. Thanks Jeff

Lee thanks for the reply. Got your email as well thanks there too. I thought I would post here rather than email as I have spoken too a few fellows and sparked an interest. Your comments on the atomic of not knowing any one that has done this job. Do you see any gain in going to just a magnum length over what a 357 or 41 magnum would have to offer. From what I want as a custom hunting revolter I think I would be as well off going back to an FA. Semi custom I think is the term used here. However I am still not done mulling this over. As to the red hawk I was thinking brand new cylinder. Oh one more thing that was thrown up in a phone discussion. What kind of clearance is there between the 30-30 rim in the 357 BH cylinder? This was brought with the thoughts of the 475 made from the 45-70 with just about zero gap. If you follow me here. Would the 225 Winchester be an option with a bit smaller rim to gain some clearance? I don't have any 225 brass to measure water capacity against the two. Thanks Jeff

I have a Ruger buckeye 32 mag and 32-20 cylinder. I have shot a tc in 30-20 for years. So have a fair bit of an idea on that one. The 32 mag I have not fooled with enough to comment on. I do know my cylinder doesn't like the heavy I shoot in the 32-20. If I could find a lever gun for either would make me happy. The only bullets I have loaded for the 32 mag are some Hornady and some of the plated 90 trainers. I do have a new LBT that drops at 120 from my alloy but it is a gc design. Not real partial to a gc Ina wheel gun. Jeff

I have wanted a 375 in a wheel gun for a long time. I am not getting any younger. Originally looked long and hard at the super mags. Ya snooze ya loose. Before I new it they were collectors items. I was scanning through some sites this am and ran across this link to here. WOW a darn good bunch of reading gents. I had always thought in the way of a single action 375. Could a red hawk be used instead of a black hawk? I cast my own pills. Is there a mold you fellas like or are using flgc's. Flgc= full length gas check. Or just do measuring and go custom and be done with it? Who do you recommend on this conversion? One more question any one built a lever gun in this? Thanks Jeff
