Does anyone feel bullet runout can contribute to the flyers problem?
Here is me jumping up and down raising my hand with a big yes. I did alot of tests on this, with my 308 and 300RUM's, and segargated the ammo based on runout, and the runs with runout less than .001", had virturally no flyers, compared to 50% of the time the ones with >.007". I think I did show on these two guns, that anything less than .005" runout made virturally no difference.
But also found on guns like my 7mm08 and 270, runout didn't make a difference. Only thing I could figure is my bullets are .002" from the lands.
None of this is gospel but is what it is. Free info on the internet.
I feel bc's work is of value..... I personally just don't see how you can load a bullet into the lands of a rifle when their axis are not parallel and not assume that flyers will happen. (or should be expected.....). This may be more pronounced with some caliber/cartridge combos than others. Correct your runout........If it exists.......
