I have read a time or two in the past about paper patching grooved bullets and was hoping some one could give me some info on how to do it such as how to size them and what size would a 30 cal bullet have to be sized to before adding the patch and where does one find patching materials? In other words i am seeking help from start to finish on this subject. Thanks, Scott

I have patched grooved bullets since the 70s. Fact is I have had and sold half a dozen smooth sided moulds that were made for paper patching. Just had better luck with grooved. For my 5 30cals I size the as cast bullet to .3015, wrap with 2 wraps of 16# green bar printer paper. Lube with BAC and run through a .310 push through die. I use pure lead up to 2200fps, BHN 12/12.5 up to about 2600fps and BHN 15.5/16.0 if I go faster than that. Linotype doesent seem to have a top limit but isnt good for hunting. Hope this helps. Any questions and you can e-mail me, pdawg.shooter@gmail.com. Good luck and have fun!

It will depend on your rifle, the cartridge and your chamber. As pdawg, I have loaded grooved cast bullets for my rifles. In general I have taken them 'as cast' and patched them with two wraps of paper. The type of paper will vary depending on the size of the bullet and the chamber.
Generally, I have used typing paper and once dried, lubricated by hand with lithium grease. The bullets need to slide in smoothly into your case (a Lyman M die works wonders) so that the paper doesn't tear.
I also try to keep the base of the bullet, and paper twist, no deeper than the end of the neck, so that it doesn't protrude into the body. Minimizes the chance that the paper will be ripped on ignition.
I would suggest you try a few, and see how they fit into your cases, and then how they chamber.

I have no problem patching grooved bullets.I have big problem with patching bullets with gaschecks.If I size the patched bullet,it will tear at the base,where the gas check is.

There is NO need to check a paper patched bullet. The paper protects the bullet as well or better than any check. The paper actually acts as an insulation to protect the bullet from the hot gasses.

I patch several different grooved bullets for use with smokeless powder.
I prefer to use bullets with the gas check shank but no check.
I size the bullets so that when patched the bullet is a snug fit in the throat. I also bring the paper up the nose so that the paper is in the throat. If I chamber a cartridge and then extract it I will have a small black ring up at the top of the paper from oil or fouling.
I generally use the thickest paper I can buy for patch paper. My father uses the thinnest paper he can find…
For general in formation on patching a Google search will bring up several long articles on patching.
For specifics the BEST written word on paper patch bullets is the NRA’s Cast Bullet Handbook and Supplement. The books have E. H. Harrison’s articles on patching and the follow up questions asked over several years following.
The second best source of information is Paul Matthews’s book – this has been reprinted and is available from Wolfe publishing.
Look for the NRA’s cast bullet handbook at Ray Riling books – I think they still have them – they are long out of print I believe.
While I have lubed patched bullets with a variety of things I now generally use Lee case sizing lubricant. This is a die maker’s wax and not only water proofs the patch but also toughens it for feeding through the action of lever-action rifles.
I often fold my patch tails rather than twist them. I find this method a bit better when using smokeless powders as it is in effect a paper wad or gas check.
Do not overlook NEI and their paper patch molds. I have the .301” NEI 160-grain bullet and it is a fine bullet accuracy wise in all .30 caliber rifles. This bullet has grooves smaller than the lube grooves on a lubed bullet and a slight boattail the bullet works very well.
Here is a picture of the RCBS 200-grain gas check bullet seated in the 350 Remington Magnum and this is an excellent combination for the Remington Classic rifle.

Thanks for all the info... Pdawg i sent you an email and am thankful for your time. I am going to get this figured out yet!
