PP rifle question

[pbbutz]

Can the base of the PP boolit project past the neck and into the powder space or is that going to be trouble like most cast applications? I am new to this PP business .....:confused:

It has been my experience, it presents no issues.
That is in my .30 cal., and my .303 British.
I load them like jacketeds.

[303Guy]

I load them like jacketeds. Oh! I had the idea you didn't. Interesting!

There is an instance when it likely should not be done and that is when a 'dough-nut' exists - one significant enough to influence the boolit anyway. But then that is true of J-words also.

[docone31]

I wrap mine .001 over jacketed spec, unless the bore is larger such as the .303. I seat them as I would a jacketed bullet without a crimp. I use jacketed load data.

[303Guy]

docone31, is it permissable to allow the boolit to be pushed back into the case a little by virtue of it contacting the leade? Or would that create inconsistencies with seating depth? (It does create problems with extracting un-fired rounds! And Murphy's law states the boolit will pull out the case on that one occasion when you have not used a filler and you have forgotten your cleaning rod at home! [smilie=1: I just know these things instinctively. :mrgreen: )

[docone31]

I do not let my castings touch the leade, I set them as per SAAMI specs as if they were jacketeds.
That has been my winning combination in my rifles.
I use full loads with no filler.

[303Guy]

Oh! Thanks for that! In which case New 303 Brit mold is ready for production!

The whole time I was thinking I had to fit the boolit to above the shoulder junction and have a near contact fit with the leade. Is there a limit to how far past the shoulder juction a boolit can be seated?

[docone31]

Paper patching seems to behave differently than lead castings, even though they are based on lead.
With my .303, I have yet to see evidence of anything detrimental from seating the bases below the shoulder. I do not bury the base in the case, but all my loads have at least the area the check would take up below the case shoulder. When I set them high in the case, I got fouling around the neck. They still fired the same, but seating them lower than a casting would be set did not seem to make that much difference.

In my 300RUM with its short neck, my 200 gr PP always extend below the base of the neck. No problem. I load in un-sized cases and seat the bullet into the lands. With a BHN of 18 I have gotten 3000fps with good accuracy.

[303Guy]

That answers the original question then. So it seams we have a fair amount of leeway with patched boolits. Great!:drinks:

pdawg_shooter..
How tight are your patched boolits in the un-sized necks of your brass?...Can you hand seat the boolits or do you use a seating die?
thx..

No I cannot seat by hand. I use a die and then a Lee FC die to remove the bell.
