Neck Sizing Question

I have 2 Remington 788's in 243 Winchester. The only difference I see is that one has a shorter barrel than the other. I have found that brass fired in one will also chamber in the other (just a little tighter in one) after being fired and before being resized. Got me wondering if it would be okay to neck size the brass fired in both and shoot them in either rifle or should I keep the brass separated? It would be great to come with a single load that would work in both guns.

You really shouldn't neck size brass that will be used in different rifles even if they are from the same manufacturer and the same model. There are always slight differences in the chambers. I highly suggest if you want to neck size only you keep the brass from each separate and you will be fine.

I agree with ArchAngel. I would full length resize all your cases and load them together as one bunch. You might see some longer case life by neck sizing separately but the extra time needed is not worth it and your 788's probably wouldn't notice the difference.

Partial full length size to just fit the tighter chamber, making sure you do not have excessive headspace in the other. (Probably fine there)

I am not sure that Parker can't use this option. While we would all agree that for best accuracy each rifle should have its own neck size, but with one necksizing, wouldn't there be less brass work than full or partial resizing. In the one chamber the neck size would be perfect and that particular case would expand less in the next chamber than one full or partial resized.?????????

Just wondering.

Walkalong ... beat me to the answer I was going to give. By doing what he said ... you'll work the brass less than doing the full resize. I partial full length size all my rifles except the AR. Have been doing that practice for 30+ years ... still working for me.

I agree in general principle that neck sizing for 2 different rifles isn't a good plan, per se, but there is one easy way to find out if it might work in this case--try it! Not much of a loss if it doesn't--in fact no loss. You'll simply have your answer.

Ah Moosehunt ... truly a logical man. That's a good thing. And experimentation, trying failing, trying, suceeding.....its kinda what got the human race where it is.

I can see it all now back in 50,000 bc on a paleolithic forum ... a guy wonders hmmm, I wonder if I flute the point and make it thinner if it will kill one of them there mammoths better.....:rolleyes:

Thanks all! I may give it a try. However, a partial full length would save me having to buy another neck sizing die.

parker51,

what's wrong with segregating brass for the two rifles after neck-sizing? i like not having to lube and de-lube cases...speeds things up and potentially more accurate to boot. my vote is for lee's collet sizer die if you decide to go the neck-size route.

you have two 788s? i foolishly let go on one 40 years ago and still regret it.

You're probably right about this. I've just got a bad habit of grabbing the wrong box of ammo when heading to the range (or woods) and thought it would eliminate the worry if the same bullets would fit in both guns (though I have grabbed 30.06 ammo and found I had a .270 with me in the tree) (amazing what effects opening day of deer season still has on me after 40 years). I just picked up an RCBS Neck Sizing set off e-Bay for $25.00 so it won't be a major investment either way.

I just picked these up recently and they have quickly become a couple of my favorites and hope to have loads developed by hunting season. They are both tack drivers using commercial ammo so I can use it if I don't find one in time. It seems the older I get the less kick I get getting kicked by a .270, 30-06, 7mm or 300 Win Mag so these .243's are just the ticket. I'm still looking for one in a 6mm or .308 but all I've seen have either been too pricey or looked like they fell out of the truck.

It should be OK for the range but for hunting its best to FL size. You dont need problems in the field. The only advantages Ive found to neck sizing is that its just less force involved when loading and less case wiping.

Parker, why not try what you suggest and find out for yourself? Whatever you learn will be more useful that a gaggle of opinions.

It is good to touch the hot stove, even though thousands have said "the stove is hot".

The only way to really learn what "hot" is ...is to have experienced it yourself!

parker51,

amen on picking up the wrong box...my range is only 100yds away and it still ticks me off if i grab the wrong box of ammo...but i'm lazy, that's why i like neck-sizing when i can get away with it...potential for better accuracy is just a bonus.

788's were supposed to have been favored for custom builds by silhouetters because 788shad the fastest lock-time of any actions out there...story was this embarrassed remington who didn't like the idea that their "cheapie" outperformed the 700.

like you, i got tired of getting kicked by the heavies...maybe that's why i enjoy my cast bullet, 1800fps loads from my milsurps so much.

New to rifle, why is it best to fully size for hunting?

Thanks.

how do you partially full length size?

"..story was this embarrassed remington who didn't like the idea that their "cheapie" outperformed the 700."

Yeah, that story got circulated when the 788s were still in production. More likely it was campfire BS and speculation by a bunch of pre-web gurus with absolutly no validity. Fact is, the 788s didn't sell well because they were even uglier than a Savage at the time so they got dropped from the market and we then got the Md. 600/660 which also failed to sell well and got dropped in their turn. The Md. 700 lives on, king of the hill since '62, neigh onto 5 decades now.

New to rifle, why is it best to fully size for hunting?You know they will fit, instead of, oh darn, these are for the other .243.
how do you partially full length size? Instead of screwing the sizer down to hit the shell holder, you screw it down to size just enough to fit your chamber, instead of all the way.
