Re: Help... I'm completely baffled at this point.

I personally do not loose sleep over this issue. What I do is I set my seating depth so that only a miniscule of the bullet is in the neck, no crimp and as I chamber the round it is seated at the lands. But, for hunting I do seat to the listed OAL and crimp.
BTW, I have been useing Lee since the early 80's and have no problems with their equipment but, I would loose the that knuckle buster and get a o press mounted on your bench if at all possible.

Measure 7 or so unloaded bullets, and set them in a line according to length. Set the seater die with the bullet in the middle of the line. That should help with your difference in oal.

Re: Help... I'm completely baffled at this point.

I just thought of something. Groups are .833 at 200 yards, Right? so that is .42 MOA. If you are getting .42 MOA at 200 and seating depths are not consistent, plus concentricity is likely off, then that is not embarrasing accuracy.

How did you determine 3.4 was the magic seating depth for this rifle?

Re: Help... I'm completely baffled at this point.

First , a .833 at 200 yards is some fine accuracy for what you are working with. Second , if you are measuring lenght over all that would explain the variations in lenght. You need to be measuring to the ogive. Third , if the long nosed bullets are bottoming out you can send one off to Lee and they will make you a custom seater plug. That said , I don't think they are bottoming out. The different bullets have different shoulder angles and nose lenghts so the lenght overall and to ogive will both be different if you do not change the seating die. The overall measure will vary greatly like you are seeing and the ogive length will vary slightly with different types of bullets.
I have used plenty of Lee dies and find them to be just as good or better than most other brands and to me there is nothing better than their collet neck die. The hand press I have no idea about but the Lee Classic Cast Press is as good as any O type press. I you want the best then a Forster seater ,
Forster co-ax press , Wilson trimmer , Mitutoyo calipers and the list goes on but they will only get you .001 to .0005 better and cost a fortune. Start measuring to the ogive and maybe a bench mount press and see where that gets you. As for the smk's , fiddle with the jump to lands and see if you can find a node.

Nothing at all wrong with the Lee hand press...they work great! I know you won't believe this, but the best 3-shot (100 yard) group I've ever shot was using a Lee hand press.

Winchester model 70 w/Robert W. Hart & Son barrel (.340 neck) 308 caliber
Winchester brass--Fire-formed, neck turned, uniformed primer pockets
168 gr SMK
Large rifle primer Federal Match
42.0 gr Varget

0.017" I know, I know...

Re: Help... I'm completely baffled at this point.

The .833 3 round group was my past time out... with a different bullet altogether. I probably pulled a shot that made the group smaller. All I know is that my whole life I've tried to improve. Anyway I appreciate all of the help you guys have given me. I don have a permanent bench to bolt a press down to yet, so that's why I'm stuck with the "knuckle buster" for a bit.

I'll have to see of there is anything inside the seating die causing an issue.

Last question. I've been caught up measuring OAL since I started, and apparently I should chamber an uncrimped round and measure from the ogive from here on out? OAL seems to be just to ensure rounds fit into a mag and chamber properly? Thanks again everyone!

Skip,

Take a gander at this thing.

I made it in 1966 when living in an apartment. Been using it ever since. Never used anything else since then.

That's an RCBS Rockchucker Supreme press. Original press was the RCBS Jr. Had to upgrade when I got the 375 Allen Mag.

I can resize and bullet seat the 375 AM (408 CheyTac improved) on the kitchen table or the coffee table in the living room for that matter. (if the wiffy isn't home.)

Something to think about....
