Today I was getting about 1 in 8 shots that “disappeared,” since I was holding otherwise solid groups I figured these must be lube purges, I mean I'm a better shot than that to lose 2 off the paper./images/emoticons/134.gif Seriously, 4 rounds nearly touching then, where'd #5 go...?

Try cutting back on the lube.

Fred, if you do a test with the exact same load/conditions only minus some lube let us know how it goes. The lube purge theory sounds good but I'm skeptical that it happens that way, not that I'm an expert.  It just seems to me excess lube buildup is cumulative and should throw shots out progressively worse, not all fine then suddenly bingo! gone, then back to fine again. I can't explain those wild fliers myself, but I have my doubts about the logic behind the 'lube purge theory'.

A flier in my way of thinking is a couple inches away from the group .

Even with my old derelict leverguns with antiquated scopes I can usually keep the fliers inside 2 or 3 inches at 100 yards !

 

This lube thing sounds kinda bogus to me as I've fired as many as 30 shots without cleaning the barrel with very good to excellent results .

I don't feel any noticeable change in recoil to indicate goofy primers. Sort the bullets by weight, light ones (</= -0.3 gr) go back to the melt. Maybe later I'll weigh my brass and see if maybe I mixed up lots and have some severely tight ones.

Use bigger paper.

My experience with lube purging is having the bullet out of the group by a couple of inches, not off the paper.

Some say that only lubing the small space above the gas check is enough lube. It might warrant lubing some that way and shooting some test groups.

Now....maybe those missing shots were bullets that went thru the same hole...

You use bacon grease in your lube? Space aliens love bacon. If so they got 'em and ate 'em before they got to the target. 8-)

Fred,

Having them miss the paper sounds more like a bullet too long for the twist that is just barely stable and then for some reason an occasional one will be even less stable and tumble.

I sometimes have a similar event when trying to shoot 280 grain bullets in the 44Mag in a Marlin with 1 in 38 inch twist. Some of the holes will be a bit oblong but make fair groups -- then one will disappear or make a rectangular hole six inches away.

What caliber, bullet length, twist?

I don't think it is likely that you will solve your problem by weighing bullets, powder, or brass or trimming to length.

In my 223s I consistently find that if I lube more than the gap ahead of the gas check the groups enlarge -- but don't go wild.

What caliber, bullet length, twist?30-30, 170 gr. 91141 Lyman- 1 inch almost exactly, 1:12.

All the holes are clean and round, no signs of key-holing.

Honestly, and I'm not trying to be funny but I think you need a bigger piece of paper. Without evidence of what the bullet actually did, you're kind of shootin' in the breeze trying to figure out what is happening (no pun intended). Either that or move the target in closer. See where those flyers are going. Are they going off random or are they forming a group several inches away? Without objective data, it's anyone's guess what's going on.
