New to reloading got some questions.

[Canuck65]

Hey everyone and thanks in advance. Got into reloading for .300 savage. Watched videos and did some reading. So I cleaned all the old brass, deprimed, resized trimmed etc. So i was seating the projectile for 300 savage. I’m use Rcbs dies but also have a lee factory crimp die. For some reason after using the seating die and the factory crimp the projectile is loose. Can’t pull it out but can wiggle. I did ream the inside and outside of the . Is it possible I reamed too much? Is the case garbage or could I trim it a little bit? Thanks in advance.

I would guess you did ream too much. Try pulling the bullets and resizing. Reaming probably wasn’t necessary btw, and some framers are meant to be done before sizing, some after. Make sure you’re using it correctly. If you reamed after you sized, and yours is meant to reamed before sizing, you may have to trash that brass. Maybe not though.

Also, if your gun is a bolt action, or if it has a box mag, don’t crimp. You don’t need it if your neck tension is correct. If it’s a lever with a tube mag, then just crimp enough to hold the bullet in. Over-crimping, especially if the bullet doesn’t have a canneleur, is going to give you problems.

Yea sorry as someone said chamfering the neck. Removing any burs on the inside

Thimgs that make you go hmmmmm...

And what is the diameter of the expander in the resizing die?

To be honest I’m not sure. Is there a way to check? I’m starting to think it’s the bullet seating/crimp die. Because the necks on the case that I have not tried loading are all fine. The two “problem” shells seem to have had the neck almost pushed out if that makes sense.

Yea sorry I saw that after I posted. Didn’t know how to delete comment so just left it.

Ah ok. I did load some 30-30 Winchester for a marlin 336 and everything was fine. I’ve got a savage 99 with the internal rotary mag. I’m gonna try to re size and see what happens.

On this website I do not think that you can delete a post, but you can edit it (change your words). I think minimum this system wants to see is three characters on a post - so you will see some posts like that - poster put up something, then changed his/her mind and most he could do was "edit" and replace with any three characters - I suspect a Mod can make a posting disappear completely, but you would have to contact one, to get them to do so.

As per earlier posts, if you are loading for a Marlin in 30-30 or a Savage 99 in Savage 300, not sure why you are reaming / neck turning at all?? Do you have something unusual or non-standard about your chambers? If those are straight production guns and barrels, maybe focus to dependably get several batches done that simply go "bang", every time - work on your technique - is possible at a later time that you might own different oufits that will require neck turning for best results. But, if you are just starting out - load up perhaps 20 rounds - shoot 4 x 5 shot groups. Now try something else - like neck turning or whatever - another 20 rounds - another 4 x 5 shot groups - did your average get better, get worse, or stay the same? Only you can determine that for yourself.

There is such a thing as "round robin" shooting - so first load's five round group at one target; then altered load's first five ground group at second target. Change both targets - second five round group at one, second altered loading at other. And repeat for third and fourth. Or just leave same initial targets up and end up with 20 round group on each - but five from one load at one target, then five from other load at other target - sort of takes you, the shooter, out of the comparison. That also deals with changing light, change in atmosphere, change in temperature or humidity - not that one load takes all the change, that the other does not see.

Is likely good to know what really high end guys have to do - but does not mean that is of any benefit to you with normal store-bought gear. Perhaps get and learn how to use a micrometer - failing that, get a calliper - you need to be able to measure to within 0.001" or so - many would consider that too crude - they would want to see within 0.0001" or so. Understand there is a difference between trimming for brass length versus peeling for neck thickness - two different exercises that accomplish very different things. If you are loading for a rifle, trimming for brass length pretty important - as mentioned, for past several thousand rifle loads or so, I have NEVER peeled a neck, although I tried it at one time.

OP - Sounds like you screwed up on sizing a few brass. Perhaps you forgot, or short stroked the press. Take your remaining sized brass, check for bullet interference by hand. If OK, try seating a bullet, see what happens...
