a while back ,in another thread, there was disscussion of a "proper" sizing die for the belted mags(300 win mag to be specific). it resolved around proper sizing at the area just above the belt if i recall correctly. does anyone know if these are available now ? at the time of the discussion none were available.

thanks

done!
thanks
as this die is used with a fl die, do you have a preference in fl dies ( i'm assuming a fl bushing die)?

question two how often or always ?

for you 1000 yd guys...do you use it every time , every other ? or what ?
?

still learning.
thanks

Mike,

I don't use any FL type die for my .300 Imp. HG... Mine seems to like lower than max charges of Re 22. I am getting 2950 with 210 VLDs and it shoots well that way. Less pressure isn't always so bad. I load more moderately my 6.5-284 and 6 Dasher as well so I don't have to worry about hot days making my brass to sticky in the chamber. I used to but it just started to seems like I was getting diminishing returns for all of the extra work to be sizing harder and wear on my brass and barrel. They say RWS brass is tough as nails and mine seems to be holding up well. I see what you're saying but going slower would be my advice.
 
my initial plan is 208 horn amax, moly, with h1000 and h4831. berger 210's are on my list.(my number crunching says i am about the same as you with 4831...low pressure/2950 vel...LG)
i'm stuck with lowly NORMA brass...........so want to take care of it.

thanks

I think Larry will tell you to use it often. If you let the brass swell too much just above the belt his die won't fix the problem. You must use the die often enough to not let this little area grow too much for the die to slide over it otherwise it will just bump into the swell and stop as if it were bumping into the belt itself.
 
I do what Lynn does (as stated by him above); works out to about every third loading with my Lapua brass. With the Berger 210 thins, I've seen better results with Retumbo than with H1000. But I'm shooting them at 2900 out of a critter gun (shorter barrel than most target guns).
 
Belted Magnum Collet Resizing Die

Mike .......

Our popular Belted Magnum Collet Resizing Die has been in stock for the last 6 months, and the price is the same as when they were first available (back in 2001). You can read about it on our website.


In two years I've sold over 1,000 of our collet dies through Cabela's and MidwayUSA alone. However, I've found that I can sell these dies directly from my website and make the same profit. I can also keep the price down. This way I can also drop the required million-dollar product liability insurance. (After all . . . . this insurance gives lawyers much more motivation to go after someone.)

After helping shooters (one-on-one) for over 8 years, I've found that many of them assume that when their shellholder bumps their FL (or NK) sizing die - all is well. As you know, this is usually not the case, especially with belted magnum calibers. I've had numerous shooters send in fireformed and resized cases for troubleshooting. It became obvious that they also need to measure the chamber clearance (at the shoulder) so their handloads will fit in their particular chamber.

I found that most shooters are confused by the cartridge drawings in reloading manuals, and they have needless concern about locating the datum point on the shoulder. There's no need to think about all that if you just compare your handloads (at the shoulder) to one of your fireformed cases.

Our new Digital Headspace Gauge does exactly that and simply displays your chamber clearance. That makes it easy to set your die height perfectly and bump the shoulder back -.001" to -.002" and no more. Too many shooters are setting themselves up for headspace separation by not measuring this properly.
