Forster Bump bushing die for 6BR?

[RePete]

I'm thinking about building a 6BR for varmints.
I've read the thoughts about neck sizing in the 6BR information section and it seems that FL sizing is recomended.
What do you guys think about the new bump die? Do you think that bumping the shoulder back would keep the brass from thickening like the author says happens when neck sizing only? Or would you just FL size and be done with it?
This is the first of many dumb questions I plan to ask so I'll apologise in advance.
Thanks

Never appologize for a question. As for the bumbing everytime you size, you will be having more consistency in your brass, and possibly it will keep your groups consistant. I personally am going to eliminate one step every 4 to 5 times by going to the bumping/resizing die myself. I believe it is another solution to better constistency throughout. My .02 worth.

As well as RePete I`m new to the 6br .I have a gun set up for benchrest .When I bought the gun it came with wilson dies .So my question is it then advisable to get a body die and bump the shoulder back without touching the neck ? Or do I invest in a full length and use it every couple of times?

Most of the time if you have a tight chamber, and if the dies are custom made for that gun the builder will request that Wilson or whoever makes your dies to allow for minimal shoulder set back. If not you will need to bump the shoulders back every so often. Maybe not every other firing but the tight bolt closing will let you know. I hope this helps. Bill

I think you are worrying about a non issue.

The short, fat body, and large shoulder area lend themselves to a close fit.

If you are building a varmint rifle, then this fit,as Martha would say) "... is a good thing".

When the case is a tight fit in the chamber, there is no where for it to stretch.

A competitive shooter needs a loose,not tight) fit, because during a match, they may wait for a lull in the wind, and then fire all of their shots quickly - they don't want the gun to move during loading cuz the case is tight, or a delay cuz a case is causing them to work hard to close the bolt.

EVERY TIME you move the shoulder back, even if it's a few thou, the case stretches those few thou the next shot, and the stretch comes from just in front of the web,a BAD place to stretch!!)

As a varmint shooter, you are not under the time constraints of a bench shooter... you can take an extra second to close the bolt, and you will be aiming the rifle AFTER the gun is loaded, so gun movement in not an issue.

My preference for varmint rifles is that cases fit with a "just perceptible" light pressure.
I don't touch the shoulder until the bolt gets "hard" to close, then I bump the shoulder back to the point that it is still a light "crush" fit.

My FL or Bump die is set so the case is returned to a very light crush - this will maximize case life, and repeatability.

You'll get different opinions on this because shooters in different disciplines have different needs... and you will get opinions from people that have no idea what they're talking about - they are just parroting something they read somewhere else - take "where they're coming from" in consideration, when you decide how to set up your gun.

Although both need accuracy,to some degree), a varmint riffle is NOT a Bench rifle, and the ammo needs for them are not the same.

The best die for the 6BR is Harrell's FL die bar none !! When you get your gun built fire three cases in you gun a couple of times and send those three cases to Harrells and they will send you the die that fits your gun . It uses standard Redding or Wilson bushings to control your necks .

Change of plans......... I've decided to go with a 22BR. It just seems to make more sense for a varmint and paper punching rig.
I've pretty well got things sorted out in my mind, but have one question.
What's the difference in 6mmBR Remington and 6mmBR Norma?
Most components and dies that I've looked at are 6BR Rem. but I see a good deal on Lapua brass from Grafs that says 6BR Norma.
Some of the brass I've seen at other suppliers just say 6BR.
So what's up. Is this something that I need to worry about when planning to neck the 6mm brass down to 22BR?
I told ya I'd have more dumb questions, so thanks for your patience.
