Can PP bullets help me?

Buckshot!
I found the mold you wrote about, the 300 gr mold from RCBS.
That one is very, very expensive here on Midway Sweden.
That price is, 1650 SEK, ( that is around 254 USD )!!!!!!!!!

New bullets!
I found some good paper, I think.
An old "reloaders Guide" from IMR.
But, no GC added.

I have loaded this bullets with the same " hotter " load as my "maskingtape" patched.

.405, crude rule of thumb I've read on velocity vs PP is around 2000 fps for pure lead, up to 3000 fps for alloys. The patch will in theory prevent leading if it is not mutilated in the loading or ride down the barrel. The factors regulating velocity are mostly found in the harmony between throat/leade geometry vs. the many dimensions of bullet and bore to some degree. I think it more significant to look at it from the perspective of twist rate and groove depth/geometry and bearing surface of the bullet. From my own experience with the .44 caliber and 20" twist, pure lead get a little goofy as it approaches 1700 fps around 35K PSI with 300 grain RNFB bullets. Swaged and patched round balls go fast with light loads and lose their way somewhere short of 2400 fps. I dunno what it all means though....

My bullets is around 16 on the bhrinnel scale.
The "new" testload that I'm supposed to go out and try tomorrow, is loaded to 2150-2200 fps. ( really dont know if the paper does anything to the velocity)

The "maskingtape" loads is with GC, but my "Reloaders-Guide" patched loads is not with GC.

Today, ( well my wife think that I should clean the house instead of playing with bullets, but she dont understand ), well, back to the subject.
Today I sized down some of my 350 grs MM bullets, patched with IMR-paper, and loaded to very slow velocity, around 1600-1700 fps I guess.

My Marlin is one of the older, with a 1/38 micro-groove barrel, but it is very accurate with the 350 gr bullet when loaded proper.
But, the downsized 350 gr bullet is very long, and I'm not sure if it will be stabile.
Well well, I will have the answer on that question tomorrow.

Now I like to know: What do you PP bullet shooters lube your PP bullets with?

Here's what I do,also a couple of other suggestions,if you like?:
1. Spray with Teflon Spray and dry.
2. Run the bullet through the proper sizer-luber,with Alox lube and wipe off excess lube.

Or the old standby 50/50 beeswax and Vaseline

Hope this helps

Thanks!
I have a lot of beewax at home, ( used to mix my own lube )

[Buckshot]

..............Any lube that doesn't penetrate the patch works. Also spray moly dry lube is super. If you want that mould I can get it and ship it to you for a heck'uva lot cheaper then that. I think I can ship it for $11 or less.

When you wrap, the end should NOT overlap the beginning except for the 1st complete wrap.

Buckshot!
What is the price for that mold at your place?
Not 11 USD???????
That must be the shipping cost, is'n it???

This is two 3-shot groups with the "maskingtape" bullet and the PP bullet.
Still on 88 yards.
I'm pretty pleased.
If my 405 will group like this, than I'm satisfied.

BTW, does it matter for the accuracy that this PP bullets have a shank for GC under the paper?

[no34570]

405WCF
That is some nice groups you have there
As for the gc shank under the paper,I don't think it brings that much variation into the result,I mean that is a good group,you should be satisfied with that,I would
Good on ya mate

You could try some with GC on the bases and then wrap them,just to try it out and you also could wrap them with your paper and then put a teflon tape cover over them and then size them to what ever size you go for,.432?

..............Oh heck yes, the $11 I think is about what shipping would be and NOT the mould The mould is about $67 US at Graf and Son.

78 USD for the mold and shipping if you buy it for me,
In Sweden, 1780 SEK with the shipping, that is 274 USD!!!!

I will try my 350 gr bullet first, just to see if the rifle is accurate.
If that test pleases my, than I will buy that 300 gr mold from you.
