Case length problems.

So I let my neighbor borrow my reloading set-up last week to work up some rounds for his rifle. We both happen to shoot the same caliber and I had enough loose ones rolling around that I figured itd be okay for a bit. Anyways that being said I got it back the other day and proceeded to load last night. This is the Lee Classic loader, where you do it all by hand with a hammer, I'm still getting started mind you. Back to the point, I didn't happen to check my seating depth and apparently he had adjusted my dies so instead of the 3.32" overall length that I use it is now 3.19". I didn't notice till I did 5 of them and sat them in the box next to some others and noticed somthing wasn't right. I set my depth back to where it was and went back to loading but I'm curious about those short ones. If I fire those in my rifle will there be any chance of adverse effects with my rifle? The reccomended OAL for 270 win is 3.34" but I go 3.32" for personal preference. Not really sure why, I just do. I just wanted to know if I should just give these back to my neighbor and let him deal with it since that was apparently what he loaded his to, or if these are okay to shoot. Just wondering if there is a reason to reload that short that I don't know about or if its dangerous and I need to say somthing to him. Anybody got any info for me? If it helps the rifle is a stock browning a-bolt with a sporter barrel, so its not changed from factory in any way.

A good bullet puller is the reloaders best friend. I would not sweat the seating depth issue unless it caused the powder charge to be compressed in the case. I also think you mean COAL problems as your cases have not changed in length.

Re: Case length problems.

Thanks, my suspicions were it shouldn't effect anything, but being new to reloading I wanted a second oppinion. And your right, COAL is what I meant. Now to figure out how to change the title....

Don't worry about changing it. This site doesn't have that option. Just be careful and think about a pullet puller. Eddie.

The shorter loads will be ok to shoot.

More free bore normally means less pressure. It may change the group size or the trajectory But that should be it.

I would try a couple just to see, and if you are not happy, Pull the bullets and start over as recommended by Eddie Harren.

So there is less pressure with the deeper seat? Or with the reccomended 3.34?

with rifles, usually a shorter seating length will develop less pressure.

Pistols can be different though, especially the small cases like 9mm luger. Short seating with them can be dangerous. The only reason I'm mentioning pistols is the rule ( shorter c.o.a.l. = lower pressure) doesn't hold fast across all reloading.
