Case Neck Expanding.

[Malxwal]

Mate of mine now departed did BR. He had all the kit.
I'm good over the distance I shoot.
Next you'll be getting a tight throat barrel and neck turning every case.

And any reason he shouldn't?

The less people understand something, the more complex they need to make it...

Wow thought I was helping.

Nope.

Not criticising.
Just don't see the point outside BR.

Carry on, beats watching TV.

 

[Smellydog]

Not necessarily "bench rest", but striving to achieve lowest variance and most consistent ammunition.

Aye, important I guess. For shooting mice at extended ranges I guess.
What ever make you or anyone else happy.

No offence intended - just an observation, and my opinion.

Exactly. You enjoy taking a muzzle loader out to the squirrels, other folk want to hit small targets off in the distance. We all need to stick together, and as I've pointed out recently, it seems we have those self righteous and selfish types in our midst that can't see the folly of putting the boot into areas of shooting they don't appreciate.

Ok

So err how much does it shrink groups size?
Genuine question.

It's about minimising variance. Not a lot of difference at stalking distance, and indeed you'd be kinda overthinking things. But out at 1000 yds you're going to appreciate the effects of having as little variance in MV as possible.

1967 Spud. Cap screws off to change Mandrels.
Ken.
Ps. I set the neck tension at 0.002.

This type of die is the way forward after full length re size use a mandrel .002” under bullet diameter to expand the neck to that dimension

Gives you consistent neck tension and enhanced consistancy with regards velocity, / ES

All significant on target

Singke biggest difference in reducing Extreme Spread for those that don’t apply precision reloading techniques is by using a mandrel die

So have you tested it or is it just a hypothetical exercise?

I have. It does provide much better ES's. Is it really needed at normal hunting ranges? No, not really. But for long range, it definitely shrinks vertical dispersion.

Sure.

Never really fussed that much when I used to shoot long range.
I did though manage to get the 308 hot enough to stay supersonic at 1200.
That helped. What with the wind changes and the err bullet climb or dipping agin the wind thingy.
I just squirt the odd one now and then for ***** n giggles.

Best wishes. Heard from Muir?

Ironically, today is Muir's first official day of retirement.

He's doing well, but recovery has been a long haul. Last I spoke with him (last weekend) he was progressing very well. Hopefully, will get out to see him in early August.

 

[Malxwal]

Yes, I have seen the difference that employing this type of case prep makes. If I could drag myself to cleaning them properly I might see some minor improvement in ES too. But not anywhere near the difference that this, in conjunction with regular annealing makes.

He didn’t address just how much grief that little X pander ball gives the case!
Only interested in saving time.

I cant see the point of pushing the neck and shoulder down only to pull it back so for me its de prime with a uni die then size with a collet die then move the neck to what a want with a mandrel .
