Big Lube bullets and RCBS lubrisizer

[Duck Creek]

Does anyone use the RCBS lubrisizer to size and lube the .45 cal. 250 gr. big lube bullet? If so, what top punch do you use?
Having difficulties with deformities to bullet nose using the RCBS #637 top punch. It leaves a noticeable ring in top of bullet that hangs up in my Uberti Henry rifle.

Thanks

Come on DD this is a legitimate chance for promoting business here!

Thanks for the approval Roosterman. . .

The PRS RNFP Big Lube®LLC bullet lube sizes nicely with the Lyman 649 top punch.  But, it also lube sizes very well with a simple flat since it has a flat nose.  Also, if you have some JB Weld you can make a custom top punch.  Put the bullet of your choice on the die and put some saran wrap over it.  Then put some J B Weld on the top punch and bring it down on the bullet and let it harden.  Then, lift the ram and take the top punch out and trim the excess JB Weld.  Presto, a custom fit top punch.  Remember to take the saran wrap off the bullet before you fully lube/size it. . .

I have found that a simple flat nose punch will work for any flat nosed bullet unless the bullets are cast from a hard alloy. Even with soft lead I do not really have any problems. Dick's little "Pecos Pete" squats a bit but still performs well.

Thanks very much for the timely replies. I will probably give them all a try. May be frowned upon but I will plug that Big Lube bullet for the .45 Colt. I had about given up shooting black powder .45 rounds in my Henry. The lifter would start to work sluggishly after 1 or 2 stages until I switched to Big Lube bullets. I can now shoot 5-6 stages before cleaning lifter and have even made it thru some 10 stage shoots without cleaning if we have high humidity.

Thanks again

Flat top punch for those short flat nose bullets. Simple and easy.

Big lube bullets and ya only get 5-6 stages? I think ya need ta work up a different lube formula lad. Last weekend I ran 8 stages with a '73 and ya could run the lever with yer pinkie finger, and we had low humidity. No "spritzen" no wipen jest shootin. wM1

What'syer lube recipie wildman 1?  That Pearl lube half Crisco half beeswax? 

I know a softer lube works better but  other aspects affect even soft lube.

Take SPG Lube ,which by the way I hear little about here, that was softened up on request from black powder shooters. Beeswax and some secrete incredient. The secrete incredient is the clue. It must be something that sticks a film on the barrel metal with each shot so is able to spread the length of it.

In a book ,I read some of, written about lubes the author,that tested lubes extensively, had the opinion that it isn't really the amount of lube on the bullet but the lubes ability to stick and cover a micro film to the metal so fouling doesn't stick.

I'd disagree with that some. I'd say it's both the amount of lube on the bullet and the lubes ability to put the thin film to the metal so fouling doesn't stick.

Thing is regarding this post thread....the poster has trouble with the sticky lifter. That's a problem of fouling and/or lube getting to the lifter. The fouling should stay ahead of the brass case. The rifle mentioned in the beginning must have blowback problems.

Anywhoooo.....the thread starts out talking bout top punches fer bullets and turns to lifter sticking. So if a bullet goes canted a little thru a lubesizer would it be less sealable to the case it came out of being a lil deformed ? Would the case seal less if the bullet was a slightly ill fit in it from some slight deformation in the lube sizer?
I wouldn't think so but weird stuff happens all the time. Would a bullet slightly deformed thus canted let gas blow by at the important nano moment where the gas has to peak to seal the brass? Maybe the rifle needs a bullet .001 or .002 inch bigger to seal better to expand the brass better?  I'd want to know what size the bullet is and what size is the rifling grooves and what size is the chamber where the bullet sits.

Anywhoooo..the top punches in nlube sizers are there to push the bullet in but at the same time help it go in the sizer die straight.

If I have a flat point bullet and a plain arse flat top punch,that has no ability to straighten the bullet going in, I tap the punch inside the die a little with the top punch so I can set the bullet in further by hand and see/feelit straighten out before I press it in with the top punch. That helps.

Optimum is a top punch with a cupped end that has sorta funneled shape so that straightens the bullet up from the top from the top punch. If the top punch has that then it has to be wide enough inside to let the flat of the bullet meet the flat inside the top punch.

Getting a top punch that fits every bullet isn't possible unless you have a machinist make custom top punches so the top punch fits and actually guides the bullet straight. If I can't have a proper top punch I just tap the plunger plug in the die down some and finger the bullet in straight.

RCBS ,like others, make top punches for the moulds they sell. Alas not always though. Try to get a top punch to fit the RCBS Cowboy mould in 45caliber.  I learned to set the bullet in the die straight because of things like top punches not available for certain type bullets.

The PRS 45-250 bullet design comes from ol Pigeon Roost Slim.  It's one of the first Big Lube®LLC bullet designs.  This bullet mold, with all it's lube holding capacity, has been an annual best seller.  Thanks for the flowers, but without the creative efforts of Pigeon Roost Slim this bullet wouldn't exist.

Beeswax, deer tallow, paraffin and Crisco. Depending on temp and humidity I increase or decrease the paraffin and Crisco. My wife and I shot WB using my rifle and smokiless powder and lube. Took forever to clean it after that. Next time I used my lube in BL bullets with the smokiless and the fouling wiped off with a paper towel. wM1

[rifle]

The lube I use works fer everything I shoot. No high velosity stuff.

I'm surprised more Folks don't talk about using SPG Lube. Works fer smokeless and smokeful(black) too. Sorta soft but it works.

Deer tallow must be the magic ingredient. Make tallow while eatin venison steaks!  Makes fer a more harmonious outcome.

You can get a nice set of flat top punches from Accurate molds, their are 3 of them in dif diameters, and should work on every flat top bullet known to man.
Also another great black powder lube is "MCM Lube", made by Eastern Trade CO. out of PA. I use this in all my civil war guns in the N-SSA, and the ACWSA, here in Wisconsin.

I have no ties to either company
