I need to bump the necks on my brass. I just got a bump gauge and i have a set of regular rcbs full length dies and a rcbs nech bushing die. Will either die work to bumb the neck ?
 
If your wanting to bump shoulders and you don't want to touch the neck for neck tension reasons you could get a body die but at that point your having to use two different dies.

For what your wanting to do the best option would be a bushing full length die. With that you can bump shoulders and not overwork necks. Check your current bushing die also, full length bushing dies are frequently confused with neck dies just because of the bushing.
 
It sounds like you're just getting started with reloading. You should start with the basics and progress from there. Use the full length die and set it up carefully according to the instructions. Once you get some measuring tools you "may" want to make minor adjustments from there.

I'd avoid bushing neck dies until you get more familiar with reloading basics.
 
I have brass that already fit my chamber and Yes the necks have been turned and been using a neck sizing die. Now the brass is getting to where its got to much tension closing the bolt and was wandering if their was a way to bump it without changing a fl die.
 
Part of the FL sizing die function is to "bump" the shoulder - bumping the shoulder is resizing the case. If there is too much tension closing the bolt, then your brass does not actually fit your chamber.

BTW - saw an impromtu interview of like a dozen champion BR shooters, they all FL size every time.

Been loading awhile just been a few years since and havent got to shoot the same gun enough times till now to see i have to learn more about it.pic of my lil cave.
 
I can't get onboard with neck sizing because at some point your going to have to full length resize. So I find it rather pointless, I think it's one of those old things that just kept going from "that's how daddy did it" type logic. At least that's why I did it years ago. It probably did gain accuracy and brass life at the time when nobody annealed and set up dies to way oversize.

A bushing full length die and Redding comp shell holders and a guy can easily do the same thing all the time every time which imo leads to more consistency. There are plenty of other ways, but that's the easiest I have found especially if your loading for multiple chambers with the same dies.
