Work up some loads the other day for my 204 and had some good groups. I shoot five shoot groups with half grain increments. I had three or four groups that was great with one being less then .60" On all the groups I had four in this group and then there was always one flier any where from 1.5" and more away. How many flier's should a guy expect to see when shooting?

BC is correct - you should not expect any flyers provided his points are true to your rifle - meaning the bedding, barrel, etc. Also consistancy in your shooting too. You must make a conscious effort to do every thing exactly the same. Cheek pressure, how tight you hold the rifle, where it sets on the sand bags, time between shots, etc.

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.

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.......

Guess I should have got this all at once......bc says at .002 he didn't notice much if any difference. At say .020,the bullet has a greater distance to head to th side of the bore and to take on a deflected demeanor down the barrel if it has been loaded off-axis
Comments????
My '06/168 TSX load is .050 off the lands and shoots a nice little 1/2 MOA cluster......at 500 yards.
For those that don't speak MOA, that's a 2 1/2" group......
Trued up reloads is a given, and you get that from keepin' your head in the daylight while at the bench...and from using good dies.
Bulletdesign and BC's are a point of interest 'cause if it don't/won't fly right.......it ain't gonna hit right.
No rifle "good" or "bad" is gonna shoot well if the guy pullin' the trigger can't shoot.
A good shooter can "make" a bad trigger, a bad shooter harbors nary a clue on a good trigger.
Skirts, kids, little guys, and guys wearin' a skirt, whoshoot big guns well....is rare.
Good barrels is where it's at, and bad barrels can still do a lot of killin'......
Timing the bullet exit from the muzzle at a point in barrel occilation when the muzzle is at it's calmest is the key to "accuracy" when all the above is heeded/understood. Loading OCW is the path that takes you there.
