6.5 Grendel to 30 GR/Major/etc. What do I need?

I'm considering forming 30 GR/Major/whatever you want to call it from Grendel cases rather than necking up and such.

I understand that it would be a 6.5 barrel with a 30 throat.

I have a Stolle Grizzly with a LV contour barrel.

What would be the ins and outs of this?

TIA,

I kind of understand the mechanics of it.

What I'm clueless about is how to get the barrel from the standpoint that I have zero desire to shoot a 6.5 for anything other than forming the 30 Major case.

What group of folks would have one? Would seem like the long-range folks. But if that's the main group, what about the barrel profile (hence I mentioned my rig currently being a LV).

I've made arrangements to come out of 'the cave' and will call around 11 EDT.
 
Mike and I talked. 6.5, not a good idea. 30 only thing that is good. I've got two kids that shoot, no way I'm taking a chance.

It is really easy to neck up the 6.5 brass to 30 caliber.
It will be lot faster and cheaper than making a special 6.5 barrel with an oversized neck to fire form.
I guess that is what you want to do since you state you wanted a 6.5 barrel with a 30 neck??
Another way to do it would be to take some 7.62 x 39 brass and fire form it in your 30 major chamber. BUt you will come out with a very short neck.

But the best way is to just get some 6.5G brass and run it in the expander die.
If you expand in 2 steps first to 7mm then to 30Cal you should be able to get 300 pieces of brass done in an hour or less. That would be way cheaper than a dedicated fire forming barrel.
Also you might visit the http://65grendel.com/ forum. There were a few guys there that shot this round..
The 30 major wasnt any good as a long range round so don't expect any LR BR guys to shoot it. The 6.5G didn't do well as an accross the course round either. It just didn't have the horse power for the 1000 yard line.
Just think of the 30 major as a really expensive 7.62x39 AK round in a great gun.

Greg if you live in the Austin Area I will give you some used Brass to practice with.
I retire it from competition after about 20 firings.

Thanks, Ted. I appreciate the offer, but I'm a long way from Austin these days. Like 1,168 miles.

I may do my first cases via necking up, but want to try fire forming them up later to see if I get better cases.
 
30 major

Greg,

I did not understand your reply before this one, but take a cheap or burned out 30 barrel, put in a 30 major chamber. Shoot a 6.5 Grendle load in it and you have a case blown out without danger to your kids or anyone else for that matter.

OR

Use a Redding tapered expander button and take your case up to thirty in one pass with good lube. 1/2 Mobil One & 1/2 STP

OR

Did I misunderstand? I am prone to miss the point on occasion.
 
I want to try the fireforming method using the 30 cal barrel/cream of wheat method.

Was thinking about using the 30 chamber in a 6.5 and using cheapie 6.5 bullets to do it, but after catching a clue about the safety issue I don't want to go that route any more. My son spends way too much of his time thinking about his hot girlfriend to let me have something like that laying around.

I'm wanting to try this because of the issue with different neck tension I experienced in my first (and only) batch of 6PPC brass.
