Strange problem with a .257 Roberts Improved

I just got my rifle back after some improvements offered by a well s'perienced CGN'r.
The brass formation this rifle creates is of the 40* shoulder and replicates the first brass
on the left of your examples.
I agree with your findings that you have the 28* Bawbie.
Going to go shoot this gal and then make the humble decision which .257 I'm going to keep.
Great thread Mr. Newgint...........keeps us thinking 'bout the fun things in life...........:wave:
 
You have the Fred Huntington version with the slightly blown out case and the 28 degree shoulder..........all you need are some 25 cal neck dies, or you can actually load the Huntington version with the Ackley dies, just watch your neck and don't run them in so far as to push your neck/shoulder junction back. It is the less common of the 2 major improved Bob versions............Were it mine I'd run it out to the Ackley Imp in a heart beat.
 
Been looking all over for that brass, seems nobody makes it? With the price of powder, hate to fireform 50 to 100 cases. Would annealing help before fireforming if I happen to get more split cases? I guess someone did mention fireforming 6mm cases too.
Can you PM me who did the work for you Kamlooky? And what all you had done?

Thanks,


Aaron

Oh and Kam, you're not looking for 1F brass and or dies to go with that gun are you?
Firesale on the ones I have obtained.

Hey Aaron,
I was just thinking that you should talk to John Grech at Grech Outdoors in Mount Forest - just round the corner from you.
John is really into 257 Ackley Improved and other Ackley goodies, he may well be able to help you out in one way on another.
Also, John may well want to buy the die set I sold you...

I've never had any trouble fire-forming cases.
My favorites are some WW Super +P. They have a thicker web.
No cracking or stretching problems.
Mine was done by Jennings in Winnipeg on a VZ 24 '98 action about 25 years ago. Unfortunately they're not around any more.

This is my 257 Imp, its the Ackley version.
An '03-A3 Springfield, Douglas Premium barrel, Canjar trigger, currently wearing a 3-9 Minox.
Average groups are sub- half inch with most bullets under 100 gr. and average about an inch with 117 to 120 gr. loads.

If those brass chamber for you, load them up and shoot them.
No need to fire form them.
Try a few, reload and check p.o.i.
Take some photos to post here.

Thanks for the offer on the brass. Been thinking of selling this critter.
Too many eye-runs 'round here.
 
TN.........I have 150 new W-W brass for the Roberts and I sold the rifle, so if you need some let me know. Also with the 28 degree Huntington version you can just load 'em up with a good max Roberts load and go shooting.........the split shoulder was just a fluke or bad brass, don't worry about it as it will happen every now and then.........it's perfectly normal. I do not believe anyone has ever made correctly head stamped and formed brass for the Huntington version, you're stuck with forming your own, but you can still work up loads while forming brass. It does not affect the load development one bit, as the brass forms at less than 20,000 psi and neither affects the peak pressure nor the accuracy of the load.

That would be swell, save me a lot of "unnecessary shooting " if there is such a thing.
I'll PM you.

Thanks again.
