Do you have the gear to, or have you measured the lands...?...and are you measuring the overall length of loaded rounds (to tip of bullet) or to the ogive...?...
Because I’ve been a bit foggy from concussion - I wanted to keep this lot very simple - as I was initially taught. I loaded long on purpose, test chambered and kept bumping the die 1/4 a turn until the bolt would close without effort - turns out that length was over 5mm longer than Sammi max length - but the rounds did fit in the magazine by 1mm. I’ve since checked a couple other reloads and the light neck tension and rough travel might have moved a couple...as the 300wm cases I’m using is pretty tight.
This round was obviously just touching the lands and the slight twist on retraction pulled the projectile. There was almost no force required to bump it out with a rod and id think it would have fired just fine...live and learn.
Guess I know max length now lol
Im not the expert here...but when i load some, especially after finding the right die setting, i test the next 4 or 5 for length, & then still check every 8th or 10th one throughout the rest of the batch just to make sure things arent creeping...
You say that travel might have moved some bullets--do you mean moved them out...?...
Reason i ask is because id imagine any impact a cartridge takes in a case/ammo box would seat bullets deeper in the neck/further away from lands, rather than pull them further out the case, causing them to be longer...
Anyway...ill shut up as im not sure if you're asking/in wonder or just venting & got it all under controll.
Hope it goes well...
