Home Forums Hunting & Shooting Ask The Gunwriters WSM's: Full length re-size or neck size only?

Good post and thanks.

JM

I will have to try the test for OOR. My 7 WSM is also a SS Classic M70.

I have to full-length resize the cases for BOTH my .325's, or else they are hard to chamber.

I have to full length re-size both my 325 and 270WSMs or I have the same issues as Jeff mentioned above.

The long gone and dearly missed Shortmags.org site folks strongly recommended full length sizing for the shortmags. In fact a lot of folks on there used the RCBS X-dies with great results and case life. I use them for my wsm's and am getting 7 or 8 firings per case. The setup for them is the same as any, adjust die to have bit of cam-over at the end of the travel of the press handle.
I have had trouble a couple times when the set screw was loose and the die backed out a bit. Then the cases got hard to chamber and my son growled a bit! Good Luck!

I full length resize using the standard RCBS dies. The die has to be slighty cammed over against the shellholder in order for the cases to chamber.
Screw the die in just enough against the shellholder so that the case will chamber with a hair of crush fit. I also tighten down the die nut while the ram/shellholder is in the raised postion against the die. That way every thing should be in perfect alignment. Seems to work as neck runout is about .000-.002".

I'm up to 10x firings on my current set of brass(Winchester) and they appear to be in great shape, tight pockets, etc..

I prefer to neck size only. When I purchased my 270 wsm I also purchased a Redding three die set (neck bushing, body, and BR seater). I tried neck sizing only and could not get the cases to chamber effortlessly.

My assessment is that not only is the shoulder angle sharp, the shoulder also has a large surface area which when expanded through firing can bind easily.

I now body size all cases and have no problems chambering.

I always full length size for my 270WSM M70 FWT. As a game rifle
functioning is the top priority.

wsmnut (Dave) Yes, Shortmags.org is truly missed.

I do exactly what Sam details above for my 7wsm. I prefer neck sizing, but was having difficulty getting rounds to feed. Found the Shortmags advice, and have been using it with zero feeding problems since.

The main reason we we found that FL sizing better on Shortmags.org was because the brass is so thick, and pressures being what they are, that neck sizing didn;'t work as well for the shortmag cartridges.
I found that my accuracy difference was not a big issue, but chambering the rounds were.

I have loaded for quite a few fellas in all the shortmag cartridges, and this is what I found, as well as the other members of that site ....

I miss that site also, it was a lot of fun, if not neal being a bit overbearing!! ( grin)

Thanks for the great advice everybody. FL resizing for me now.

I wish the ShortMags sight was still up but it's great to have this one to go to for advice. So much knowledge here.

Thanks Again Fellas.

My son and I have used the round extensivley in both hunting rifles and match/1000yd rifles. We get our best accuracy with full length sizing. We do set the die so that it bumps the shoulder back about .003 in the hunting rifles and .002 in the match rifles. We push the match rifles pretty hard with 200 and 210 gr bullets and stiff charges of H4350 or R17 (when we can get it). Many cases have been loaded over 15 times. If you cant measure your shoulder just size till your bolt just closes easily and you should be close.

In routinely reloading WSMs (270, 300, 325 are the only ones I have experience with) I use a Redding Type S die and partially neck size. Every few loadings I use the Redding body die (+/- comp shellholders) to bump the shoulder to the correct headspace for the rifle, as IME most chambering problems are due to stretching of the case. If this doesn't fully solve the problem, then I'll full-length size. I only use WSMs for hunting, but the accuracy of these cartridges IME has been MOA or better using this routine.

Now that I only shoot one rifle in each caliber, setting the shoulder back when switching cases from one rifle to another has become infrequent.

A bit over bearing............... That's like sayin' Obama and "conservative and/or a change for the better" in the same sentence.

It had the makings of being a great and very useful forum, but in all honesty and IMHO, with his attitude and all around F*$&#* up disposition, it would have been near impossible not to have gone the way it did. Anyone could see that big changes needed to be made, starting with Neal.........that just wasn't gonna happen. Either he was just plain stubborn or a complete idiot.....neither is very appealing to most.

One God's enough..................again, IMHO.

YMMV.............

Yep.....+ however many on FL resizing. Safe and sure, especially for huntin' purposes.

Good luck...............

LOL! That's a good one. My "give a sh--ter" gets put in neutral more and more each day.

I size my 270wsm and 300wsm just like Sam said. Great accuracy and brass life is unreal. Easy cartridges to load for.

What are you guys getting for brass life?

I sure wouldn't mind getting another short-fat something or other.

Wanna buy a 7mm saum?

If it's the one I'm thinking of the answer is YES.
Set me up on a layaway plan...
