    ok so i never have used pulled 150gr .308cals before. these are ball type with a crimp ring. so i want to form some new brass to my 308 win rifle and i get a bright idea. instead of wasting some bergers i will get some pulled stuff from a friend who has them on hand, no problem right? wrong! i do all my usual work on the cases (sort, size, uniform the neck, trim, camfer, ream, sort by capacity in grains of water etc.) prime them and load them up with 46.0gr of hodgdon bl-c(2). then i get to seating the bullet. my load manual (lee) states min OAL of 2.800" i seat a round and the damn crimp ring is 0.076 above the case mouth. in order to use the ring for crimping i would need to seat the bullet to 2.724". now i know that in the scheme of things it makes little difference as i am loading for a bolt gun but i can't stand it when things don't look right :scrutiny: (the wife calls me anal :eek: ) i am pretty sure that loading them to 2.724" would be fine pressure wise as the load data is most likely for a pointy bullet (these are kind of rounded at the tip) but i am not positive.

    so my ? is this, has anyone here ever loaded these bullets in a 308 win to 2.724" or less? were there any signs of high preasure? or is the general comment something like "don't do that you will be sorry"?

    If you aren't going to crimp them, and as they are for a bolt gun you probably don't want to and aren't going to.....I'd not bother with the cannellure and where it is.

    A thought just came to me about the bullets.....Are they for a .308 or perhaps a 30-30? Assuming that you aren't going to actually shoot game with them (as you said they were for fire-forming cases) it shouldn't be that big of a deal but over-driving a projo designed for a lesser cartridge could cause bullet failure on game.

    Only other caution I'd offer is to make sure they aren't jamming into the lands when you chamber them. Even though they are short in OAL, the blunter profile could possibly engage the lands and send pressures up. Probably won't be an issue but something to check to be cautious.

    All this having been said, I'd shoot them up and be happy to be saving my Bergers for more important tasks!

    30-30, .308 Win, .307 win, 300 savage, 30-40, 30-06, etc.
    Same Same.
    I got some of the "150 gn. pulled. Haven't used them, yet.
    I trying to find the most accurate. Right now. Interesting. I'm loading .308 and experimenting.
    The old guys, I talk to, say. No crimp. Let the bullet ride the lands. I just did that. 2.845". Kinda long.
    I'm going to try, what the majority of people say is the most accurate load.
    Sierra Matchking 168gn. 42gn., 43gn., 44gn. Hopefully on Wed.
    :D
    Maybe in a couple weeks. The 150 gn. pulled FMJBT steel.
    :D

    nothin' at all wrong with being anal when it comes to reloading...I think we all are to one degree or another. :)


    What you're dealing with is the fact the bullet was originally designed for the 30-06...its a flat base bullet and isn't quite as long as one intended for the 7.62x51/308 Winchester.

    SO....what I would do is this...don't sweat it. :) As has been stated, bullet diameter is fine, and as long as you are keeping it at SAAMI spec you won't have an issue.

    You ought to see some of my 270 Winchester loads. :eek:

    I have shot a bunch of them in my israeli K98K 7.62 and K-31 swiss.not match bullets but they print just fine for paper punching and coyotes.

    I've used tens of thousands of them. And I intend to use a lot more as long as the supply holds out.

    I load both of the above (both of which are pulled) for my 308 savage bolt gun for plinking and such, and have had no problems what so ever. I usually seat the bullet to the cannalure, but I don't crimp them. They work great, and give me plenty of range practice (something we all need).

    lol doc

    tanker i think you where dead on about them being ment for the 30-06. but you say don't sweat it. is that a go ahead and load them short? or don't worry about the fact that they look like they are loaded by some n00b who forgot to push them in all the way :rolleyes:

    they realy need to come up with loading stats that use depth from the base of the bullet rather than oal. but nooo that would mean i would have to do math :rolleyes:

    A person tries to help someone and what does he get? I swear... :D


    Yeah...you wont' have any issue leaving them loaded up to the standard COAL for a 308. OR, if your using a finicky powder then you can use the crimp groove to get a better burn...try this on powders that leave more than normal residue in the barrel. I have done this and its a hit and miss...with some powders, it will close up a group even tighter, and other times it will make it look like I have my shotgun out. I only use a light crimp, though as it weakens the brass at the mouth.


    Remember, when you do handloads and aren't using them for hunting stuff, you can seat the bullet out as long as possible in the magazine so you can get it close to the rifling...that way, there is less "jump". You WILL see some small increase in pressure, though, so be warned when you do this...most reloading manuals give a full description of what I speak of here, so read up and get some extra experience under your belt and then have at it.

    Have fun and be safe jr

    FWIW I've just started playing around with .308 and hit the same COL issues that you're having. (profile of the bullet, etc.) I bought a tool from Sinclair for $12 that has a .30 cal throat cut into it and lets you measure at a consistent place on every bullet. The distance to the tip of the bullet doesn't matter so much as the closeness to the lands. (jamming into them being a bad thing). What I've done is take the sinclair gauge and measure some SA surplus to get a starting point. (Hornady 168 BTHP's being what I'm playing with). I've then been bumping it out in .005 increments and checking to make sure that when I push one into the chamber with my fingers (no bolt) and point the rifle up that round will still drop free. I've been shooting these for groups to try to figure out what my rifle likes.

    I figure that once I've got this measurement down then I can use it for any bullet as I'm measuring at the ogive (is that the correct term?) and all I have to do is play with powder and weight combinations untils I find the most accurate load. YMMV

    Have a good one,
    Dave

    Actually, as long as you are not seating the bullet into the lands, seating a bullet out farther (longer COAL) results in LESS pressure.

    Is it less pressure?

    As I think about it you are right. I was thinking that if there were any freebore, say like with a Weatherby, you decrease the freebore and the pressure goes up.

    BUT, with less chamber volume taken up with a bullet like you point out...


    It will probably balance out...no need to go full tilt, however...use starting loads. :)

    Thanks USSR! :)
