Am I right???

[sparks1]

Help settle a disagreeent...
Case in point>>> Cases necks have been uniformed. Now bullets slip right into case even after re-sizing. Friend says chuck the brass and buy new. ($1.00/case x 150 cases)
I say buy a neck sizer with correct bushing and good to go.
$50>$70 + maybe a case neck thickness gauge (Redding) for same amount of money.

Who's right and why.

Thanks

Re: Am I right???

Well your both right and both wrong

first you could get the bushing to achive the correct tension for that brass " all brass if different thickness" correct

but if the area is too thin than it wont hold Wrong

New brass correct if its a larger area for the neck

Wrong if it turns out to be the same diameter?

Measure a new piece and see whats right

Re: Am I right???

What is the proper case neck thickness? Necks were uniformed by taking off just enough to make them the same. However they were done without checking the thickness before uniforming.
My stupid mistake! I just want to get this done right. What I don't want is brass that is questionable after goig through bushing/neck sizing proceedure.
Load development yesterday was disappointing, as groups were irratic as with velocities. I know it was a waste of time/bullets/powder, but that's my fault.

Lapua should be .011-.014 I think when new. It's been several years since I measured any though.

Re: Am I right???

Seen brass necks as little as .011 and as thick as .017. That's why I use bushing sizers for everything I load but 30-30's and if I ever thought I would shoot past 200yds with it I would be using a bushing sizer on it, too.

I never turn a neck until I've done a good sampling of neck thickness and then I set up to clean up the biggest part of them.

Thin necks don't hold up as long because you are working them hard even if only neck sizing. However if you load to the max primer pockets often give out before the necks.

All the Lapua & Nosler brass I've purchased in the last few years run between .014 and .015, some of the Norma .017. I check the necks on all my new brass before I even think about reloading it. Lyman makes a tube Micrometer that I picked up on sale for less than 50 bucks that works great but they make better. Calipers not so good in my book but will give you and ideal.

If you are going to turn the necks you need a bushing sizer for sure. The Lee neck sizer could work but I just don't care for them. I've never seen the consistency with them as my bushing sizers or the accuracy.

An update on this problem...

I went to my reloading guy and asked about a Redding S type neck sizer for the 6.5 Grendel. I was told they don't make one. A FL bushing sizer yes. He said , "Before you spend alot of money on new brass or a new die, try the reg. Redding sizer for 6.5 Grendel." So he sent me home with one to try.
Hooray!!! necks are right on and I saved some money. I guess Redding cuts their dies a little smaller than Forster. Called him to relay the news, and he said to settle up with him next time I'm in.
What a guy. he could have had me spend alot of needless money on a more expensive fix. Instead he took care of a customer. Guess who's getting all my business from now on?

Re: Am I right???

I prefer the Lee Collet Neck Sizer, it does't care how thick the necks are. If you have a cartridge they don't make them for you can get one customed for a few bucks extra.
