Dear Grendelers,
Just wondering what the difference of resized case length should be compared to fired length. I have a Stoney Point (now Hornady) case comparator set. I full length resized some of the fired cases and compared them against the fired length. I have the Redding standard two die set. The Barrel is the button rifled 24" Alexander Arms with matching bolt. I purchased it from Midway. I used the A 330 insert which places it in the middle of the shoulder of the case. The difference between the fired case and the resized case is .020"!:eek:The difference between a fired case and a new unfired case is .018". They are Hornady cases. This seems to be an excessive amount of difference. I checked the difference between a fired and resized .308 Win case from my Rem 700 and the difference is only .006" (Redding S-Bushing). I don't have headspace gauges for the 6.5 Grendel so I can't check the chamber directly. I decided to back the resizing die out so I have a .005" shoulder setback. I use a RCBS Rockchucker press so I have good rigidity so the setback is consistent. Does .020" sound like a bit too much or would .005" be too tight? I haven't reloaded these resized cases yet.
Sincerely,
JD
