[QUOTE="bigedp51, post: 1705582, member: 28965"] I have seen Remington .223 cases with .009 neck thickness variations and a bushing die would not help vs a standard full length die. With average Remchester cases and a off the shelf factory rifle I see no advantage in using a bushing die. And in the video I posted by the 6.5 Guys they got less neck runout with a non-bushing Forster full length die. In the video in post #26 by Panhandle Precision he is using Lapua brass with very uniform case neck thickness. He also has a neck thickness gauge to check the uniformity and culls cases with excessive thickness variations, and he also has custom chambered rifles. So again bushing dies work best with custom chambered tight neck chambers with very uniform necks or neck turned brass. And the Redding bushing FAQ tells you to use the expander if the neck thickness varies .002 or more. And my point being much of what benchrest shooters do to their cases and the dies they use are no real improvement or help with a off the shelf factory rifles. And there is a reason why so many reloaders use a Lee collet die and a body die rather than use a bushing die. Or you can have a Forster dies neck honed (if needed) to your desired diameter and only size the case once. Below is a Redding bushing die, now look at the clearance between the die body and the bushing. This clearance will allow the bushing to move from side to side and even tilt when sizing the neck. And with uniform case neck thickness that doesn't expand over .004 when fired a bushing die works well. "BUT" a bushing die does not produce concentric cases with brass that is not uniform and fired in a factory chamber that allows the neck to expand over .004. And at the Whidden custom die website they tell you they get the most concentric cases with non-bushing full length dies. So again the results from a bushing die depends on the quality of your cases and how much the neck expands when fired. And I get very concentric cases using Forster full length dies that are much cheaper and produce less neck runout than a Redding bushing die. [IMG]https://i.imgur.com/O5m9mBL.jpg[/IMG] Below with a Forster full length die the case neck is held and centered in the neck of the die when the expander enters the case neck. Meaning the high mounted floating expander does not pull your necks off center and induce neck runout. [img]https://i.imgur.com/Y7Iyv8o.jpg[/img] Bottom line, in the Panhandle Precision video he has custom rifles with a tight snug chambers. And he has a neck thickness gauge to sort out cases that do not have uniform necks. So what type rifle do you have, do you have a neck thickness gauge and a runout gauge and all the equipment he has in his videos. So what type rifle do you have, what brand brass are you using and how many gauges do you have. So remember you can not make a silk purse from a sows ear. And a bushing die will not change your off the shelf factory rifle into a benchrest rifle. [/QUOTE]
