Double Patch Accuracy?

[roundball]

I'll be going to the range early Saturday morning to fine tune a 50yd zero on the new rifled .62cal barrel I have with .600" cast balls.

I also have about 75 - .595" left over, and 150 Oxyoke prelubed .010" patches I have no use for.

Planning to burn up the leftover .595's with two .010" patches at a time for a .020" patch equivalent.

They make a nice snug fit so there's no worry about the ball moving...besides, I'll just be at the bench loading, priming, and shooting, not walking around / hunting.

And my assumption is that they should be plenty accurate enough for plinking coke cans with a 60grn charge...any experience out there with double patches like this?

Nope, I've tryed loose fit and tight patches but not double patch. seems like it should do OK though.

Couldn't imagine why it would be a problem.

Roundball, I've used two .010" patches instead of a single .020" patch in a .54 caliber rifle and found no problems at all. It worked very well, good enough that I'll do it again if I need to. Le Grand

I have...had problems with patch burn out and large powder charges (120-140grs in a .54)...Double patched .010 cured the "problem"...This was before I had tried wads/nesting.etc and before I settled on a 80gr charge for that rifle...

Just back from the range...using a pair of .010" Oxyoke patches to simulate a .020" patch with .595 balls in the rifled .62cal worked perfectly...accuracy was precise and consistent...for all I knew I could have been shooting the .600s with .018" P/T that I sighted it in with last weekend.

I decided on a plinking charge of 70grns Goex 2F and no wad so the POI was in a different place but accuracy wise they were 100% perfect.

Shot 50 this morning...will finish up the remaining .59s' & patches tomorrow, then zero the rifled .62cal at 50 yds with the .600 ball hunting load.
