The lube used on the prelubed wads I buy are meant for use with blackpowder...by design the lube has no effect on BP...and they feel virtually dry to the touch.

I do not put any OP card over the powder...I just seat the Oxyoke or Circle Fly prelubed wad...pour in the shot...and seat an OS card...the 25th load will go down as easy as the first load did.

Less physical size & weight is better when it comes to wads over powder...however, too thin and without adequate lube you'd be faced with having to wipe the bore after every shot or at least often...can't afford the time to do that shooting trap or skeet targets or during fast action shooting for doves or crows...you need to be able to reload easily and quickly without wiping which usualy means a lubed wad over the powder.

Everything in smoothbore load development is a tradeoff...a balance of components that you test and settle on that meet your needs for what you're shooting at that point in time...a turkey load is different than a skeet load is different than a crow load, etc.

At least that's my .02 cents on the matter...
