Home Forums Reloading Big Game Rifles Belted magnum case bulge??

A shill??? Come on bobski, give me a break here. I'm relatively new to reloading and am a total neophyte when it comes to loading belted cases. In a quest to increase my reloading IQ, I've become a voracious reader/researcher of all things reloading. I just purchased my first rifle(Mark V Deluxe-270Wby Mag)that shoots a belted magnum and want to learn as much as possible about reloading for it. Just so happens I've come across the bulging case issue a few times and was curious. I thought since this site seems to have lots of knowledgable folks, I'd inquire about the case bulge issue. Got it???

Thanks for your concern though.

I think it is pretty bold for some poster to accuse a guy they don't know of running a scam because they never encountered the problem.

It exists.

The bulge is alive and well in some Norma brass.

I bought one of Innovative Technologies dies and it works quite well. He was out of dies at the time and I had to wait a bit for it but it was worth it.

You need to keep things clean and use Imperial sizing wax but it does the job.

No incipent head seperations so far either either.

I have a couple of .308 Norma magnums. One I bought and one was a gift from an older friend.

With the gift came dies and a bunch of Norma handloads/brass etc [Over 300 in all] as well as RCBS dies, new cases and three boxes of factory stuff.

Virtually all of the reloads had been loaded several times and had the bulge enough that they were getting hard to chamber in the gift, a P-14 by Winchester and essentially impossible to chamber in the other rifle, a Mauser even after FL resizing.

Both rifles get shot a lot and Norma brass is fairly expensive. It also has/had a rep for being a bit soft and having the primer pockets loosen up too. Brownell's sells a gadget to tighten those up but I haven't tried that.

The only other friend I have that has the problem shoots a .300 Weatherby FWIW.

I partial size the three belted magnums I work with a lot and the third one, a .338 has never exhibited the problem.

I have never had a case failure with the .338 either. I do toss the cases after ten reloads.

Nothing in your post clarifies anything and you don't state it occurs during reloading. You're compressing the outside of the case. It's pretty difficult to cause the case to bulge out if the sizing die is even remotely close to SAAMI specs; all the force is compressing in so how can it bulge out? It's not a balloon with pressure from the inside during sizing. I don't think I could do it if I tried and I'd like to see someone else do it whether a competent or incompetent reloader.



Cases don't stretch at the shoulder, they stretch in the body near the web as shown in your picture. And in sizing the shoulders compress, not stretch. That squeeze is what elongates necks and ultimately requires trimming.

That "stretch" is anywhere from .014" and I've seen the gap exceed .035" a time or two. That stretch is at the first firing when thinning of the body results just forward of the web.

If cases are bulging during reloading, the reloader doesn't know what he's doing. Just how can a case bulge forward of the belt while it's being sized?




Compare at what chamber? The rifle? Why not just measure? I'm equipped but you're double-talking here.



Your sarcasm is also overwhelming. If you're equating "friendliness" to skepticism, you're certainly right about at least ONE thing.

I've run into you on at least 3 sites where you've been laughed right out, and on one even strongly told to stay away. That's because where I've hung out there are usually MANY knowledgeable and competent reloaders. I've yet to hear one say that die is necessary or even useful, much less from someone whose knowledge and competency I respect.

Got what?

Just asking.

I've seen your gauge. It has merit. I see no reason to change from my way which also works well and I'm comfortable with it.

Peace be with you.

Sort of new here myself, so please someone tell me if I am out of line here?

But for a someone that just purchased their first rifle, and is "relatively new to reloading" sure has their .25-06 dialed in.



Just Saying.

Also, just curious, you have any links or references as it.... "Just so happens I've come across the bulging case issue a few times and was curious."

Just curious, getting back into reloading after several years away, have retired pails full of worn out belted brass, but have a hard time believing your question has much merit?

It has never been a huge problem.

Thanks

I'm a big believer in neck sizing the belted cartridges, but never with full length dies. I have had serious problems with using FL dies to neck size, or PFL, as the shoulder was pushed forward making chambering difficult. When neck sizing, I use neck sizing dies.

Recently bought Lyman's collet neck sizer for the 300 Win Mag, and it's a dandy. It squeezes the neck around a mandrel. The only problem I had was that the stock mandrel wasn't sizing the necks small enough to hold the bullets firmly enough, so I bought one from Lyman that is about a thousandth smaller than stock. Works perfect.

I'll jump in and play the game. I have one of the innovative dies and like it and would buy another. I have a friend with a couple of very accurate 270 wby custom rifles. They get the "bulge" within 2 reloads with my hornady dies. The first night I got the innovative die we "reclaimed" over 100 cases. The die was paid for.
Before ebay quite selling brass I bought a ton of once fired 7mm mag win brass. I use the die on these before I convert them to 257 wby. I like the die cause it shrinks down the brass to new dimension so when I run them into the wby die the energy of the stroke of the press goes into forming the shoulder and neck cause there is virtually no resizing of the body. So, there (at least for me) is another great use of the die.
Not everyone needs it. I like having nice stuff and this is a great addition to my "tools" of reloading.....and Ican tell you overall I've spent alot LESS than many people I see.

This is un-real. I come here looking for info on reloading a belted magnum and end up with a couple of jack-azz's accusing me of trying to sell some guy's product I've never even heard of until a week ago!!!

Hey Kevin...you possess the reading comprehension of a 3rd grader. I didn't say the Mark V is my first rifle. I said it's my first rifle that shoots a belted magnum!!! I do have a 25-06 and I do load for it. I also load for my 220 Swift. Last time I checked, neither of those contain a belt. As for loading experience, I do have very little compared to most. I've loaded about 150 rounds between those 2 calibers. I would call that minimal experience, relatively speaking.

Have you and bobski perhaps forgotten to take your meds recently??? What a couple of azz wipes you two are!!

Speaking of farm animals:

"I learned long ago, never to wrestle with a pig. You get dirty, and besides, the pig likes it." George Bernard Shaw.

on ocasion I get that "click" when lifting the bolt handle the last little bit,and was told that the area just in front of the belt is the culprit,because the die cannot size this area all the way to the belt,I never get the "click with new brass usally with 2nd and third firing's,both of my 300 win mags experience this problem,I'm sure I'm not the only person to experience this, Idea's

Gotcha!

Thanks!

As the larger point, as Fan1 suggested, doing a search as to how often bulging belted cases comes up on the web.

What is the chance that someone brings up the problem, most do not believe that it's that huge an issue, and someone else comes along with the solution?

It's funny reading when you get to the point where site owners give warning about marketing!

Back in the day, early 70's, reloading with my Grandpa, there was not a lot of equipment available. Now we are very fortunate that some will take on issues, however frequent the problems are, and manufacture solutions.

I for one will go for more of a direct approach, it seems more honest.

Kevin

How did you guys ever advance from shooting muzzle loaders?

- Innovative

Is that like prison sex?


The more you fight it, the more it hurts.

Stop fighting, relax a little bit and it won't hurt so bad.

You might even get to where you like it.


Does this apply here?

When they gots too heavy to carry when you tie a sharp rock to the end of them!

And some them critters, however so tasty, ducks when you swing the other end at them.

Ever conciser a video describing and using the die?

My comprehension is not that good?

Hi,
I have been a handloader for 30+ years. My favorite rifle a 375 H&H with it�s belted cartridges have never given me any problems. It is a myth IMO that belted cartridges give a shooter/handloader problems.
Maybe they are just considered "old fashioned" and the manufacturers need to sell new and more guns (with non-belted cartridges).
How many owners and longtime users complain about this belt? Not many.

"Why do some get so freaked out?"

Larry, if some folks admitted they don't already know every thing it would hurt their self image, you know?

Personally, I find all the pontificating that "If I don't need it, no one needs it" to be amusing!
