been reading here about paper patches with wadding to keep patch up on boolet

I'm not up on R17 loads in the 06, but why can't you use the same load assuming that it is within safe pressures?

If you look back in the threads you'll see that the more successful PP loads are very close to the same as used with jacketed bullets. If it were me I would go ahead and try it.

Starting loads for copper-jacketed bullets of similar weight with the slowest powders listed seem to be a good starting point for most paper-jacketed cast boolit loads.

You don't want the patch to stick to the boolit once it leaves the barrel. The patch is held onto the boolit by being tight on it. Pressure between the boolit, patch and bore hold the patch to the boolit by friction while the patch slides in the bore. I've used tail-less patches and they stay in place. The wad is formed by a twisted tail that gets squashed over the boolit base. That's if one uses wet patching with an overhanging tail. I dry wrap but I dare say when I finally get up to speed I'll go with wet patching as it's faster in batch patching.

Survival Bill,

There are many different ways to PP a CB and you'll find them all here. Try them all and see which one works for you.

Here's what I do. I spray all my freshly made CB with dry Teflon and then size to 0.001"-0.0015" above bore diameter. I do not remove the Teflon coating. I then wet my Vellum PP with a solution of water, carpenter wood glue, and baking soda (makes Vellum absorb more water). Let dry overnight, tumble lube in a baggie, dry (minutes) and final size to groove diameter. My PP are not glued to the CB, as I can easily remove any PP from the CB with my fingernail.

You might want to read some of the threads in this forum on using Winchester progressive ball powders in PPCB loads.

Welcome to the wonderful world of PPCB!

Best regards,

I use RX 22 or Winchester Supreme 780 for 100% loading density in .30-'06 with 160-grain PP boolits. RX 17 is a bit fast IMO, but I'm sure it will work within a certain velocity window.

WS780 for 100% in the 30-06? I wonder how that would work in my Brit?

Survival Bill, you can glue wads and patches but they just must not stick to the boolit at muzzle exit. Most glues don't stick to lead once dry so the trick is to use an appropriate glue. Things like stick lube and beeswax will stick the patch to the boolit. Paper glue won't.

I tried wrapping the patch with a card wad on the boolit base and found it rather difficult. I thought of glueing it on but wasn't sure how. Maybe if I use a glue that keeps it there? The wad stays on the boolit for quite some distance anyway so why not make sure it stays there? It won't do the boolit any harm in flight. Now to make a punch thal punches the right sized wad ...... Thank's for the idea!

I can't find volume data for WS780 right now, and a brief search for a .303 case came up empty as well, I think I used the last one I had for a .410 shotshell experiment. All I know 60 (sixty) grains is about a case full in .30-'06 and doesn't overpressure a 160 grain boolit. Someone with a current version of Quickload might be able to tell you more.

If you use a grooved bullet, sized to bore diameter +.001/.015, patch wet with a lot of stretch, when the paper dries it will shrink into the grooves and lock the patch on. Glue just increases the chance that the patch or parts of the patch will stick to the bullet. If this happens you will get NO accuracy.

Quickload says 303 Brit, 200gr. boolit, 100% fill of WW780 should be good for 38KPSI and 2200 fps in a 24 inch barrel. Pretty warm but well within the limits of a sound rifle.

[geargnasher]

Thanks for running that, Nobade.

Thank you, Nobade. 38kpsi is quite a mild load, well moderate maybe. The velocity is about what I'm getting now with AR2209/H4350 at 87% load density. I'll have to make a trip to the gunshop!8-)
