Can you paper patch a jacketed bullet and maintain accuracy?

Can you paper patch a jacketed bullet?
Does the bullet need lube grooves to hold the patch better? or are smooth sides OK?
I am wondering if I can use one of the heavier, higher-tech 308 diameter bullets like a 180 TSX in a bore that is slightly larger (.310-ish). 
Anyone have any experience patching jacketed bullets?
Thanks!

P.s. the issue I am working on is this one,  http://www.gboreloaded.com/forums/index.php/topic,238139.0.html  and I would love to have a nice bore-sealing projectile with great terminal performance; if a paper patch will do the bore-hugging, the plethora of great 308 bullets ought to produce a good hunting performer.

don't know but want to see ansewers .
A guess is it should work but would add one more varable so would it really be an advantage ?

[cpileri]

Thanks and true, it is another variable.
I think i am thinking ahead to the post-lapping phase:  my .3095 bore is not going to shrink after the .3085 constriction is lapped out; so I will still have an oversize bore.
I measured an unloaded TSX today and is measured .308 exactly.  So no matter what I am looking at needing a projectile larger than 308- unless there is some obturation from the core lok or other 308 bullet that fills the grooves.  But there are all those nice premium bullets in .308 that i willhave to pass by, or will I???
 
OK, fine, i will wait.  Am trying out the core loks and others tomorrow.  And hope to have the lapping kit soon!
 
Just for fun though, i took a zigzag cigarrette paper (no i dont smoke, I use them for paper blackpowder cartridges) and wrapped it around until it was .310.  Wasn't too difficult.  Looks kind of neat-o, actually.

How about 310 bullets ?

[cpileri]

well sure 310 bullets are an option. But there are so MANY more in 308, that I would love to be able to use them in a 310 bore rifle.
So if patching a jacketed bullet "works" in terms of accuracy and terminal performance, which my google-fu so far indicates it can, I will have more choices to draw from.

My first suggestion is get the proper diameter bullet. Reading on the other forum I think that your using a semi auto. Right???
Your trying to patch a .308 diameter to .310-11, there is no practical thickness paper to do this. Patching a jacketed bullet with the thinnest onion skin paper that I know of is .00148 thick, lets call it .0015 multiply this x 4 you will add .006 to the diameter of your bullet this will give you a .314 diameter bullet this will also cause you more problems like excessive high pressure from the over sized bullet and not onlythat  if this is one of the foreign military rifles it will cause feeding problems and you might have parts flying all over the place from the high pressre if that round does chamber in a semi auto rifle.
Besides a repeating rifle is not friendly to a PP bullet.

Hello, cpileri.  Yes you can.  There was a write-up in Handloader magazine a few years back by Ross Seigfried.  Recommends rolling bullet over coarse single-cut file to "Knurl" for easier paper gripping.  He was patching up std. jacketed for some odd-ball European sporters.

i pp for my 45-70. accuracy is as good as any lead boolet

[cpileri]

Thank you all so much!  Now there's another Seifried article I'd like to get my hands on!  That guy must be an interesting writer.
I might give this a try just to see what happens.  In the few i have rolled with the zigzag paper, the dried paper seems to cling to the jacket a little too well; I cant pull it off with my fingers.
I hope it releases when fired.
 
Anyone have some subjective or objective measure of how snug the patch should be when dried?
 
Thx!

Hello, cpileri.  You don't want the patch to turn on bullet when it's dry.  I have a couple of .40 calibers I would like to try P.P.  But I am kind of burned out on this type bullet for awhile anyway.  You see I spent 1 1/2 shooting seasons shooting nothing but P.P. out of a .22 Hornet & .222Rem.  I had Tom Ballard of Ballard moulds make up an adjustable nose-pour.  I must have tried about every type of paper..even drafting Velium..a very tough plastic type coated paper & Teflon tape.  Got some groups that matched the best match jacket bullet accuracy..next group would be 1 or 3 touching..the rest patterns!  Finally came to the conclusion that unless that patch comes off at the exact same instant that all the other bullets patches did..you are going to have fliers.  That and the fact the .22 size will just about drive you nuts!
Best of luck!

The patch will be cut by the rifling and come off when the bullet exits the barrel.  Jacketed bullets can be patched, you need to come up with the right bullet paper combination to achive the desired diameter.  I have used 458 caliber 500 grain bullets and patched them to use in a 475 #2 Jeffery rifle.  Accuracy was good enough for hunting.

No.  Not in this instance.

I'm new to paper patching but I read the Seyfried article and noted that he talked about patching a .308" Nosler 200 grain partition for use in a .318"   8x57 mauser.  Said it worked very well.

Is it feasible to paper patch .358" bulltes for use in .366"  (9.3mm)  calibers?

How about patching .416" bullets for use in .423" bores (i.e. 404 Jeffrey)?
