Rem 700 .243 to ?????

So fellas

after some thinking and discussing this topic by e-mail to a fellow shooter from Ontario I have thought about the 20 PPC.

Why, I already have a 6PPC Redding full length neck die in hand and can get a Wilson seater for it.

This is what I am wondering now.

If I send my existing sizing die to PT&G to have a reamer cut to work with the existing die, is there anything I should be concerned about?

I guess what I am trying to get an answer for is the slight issue with the Beggs cartridges and the click at the top. The dies that were made for the Beggs cartrdige appeared to not size the base enough. Gene said 2 ways to fix is polish out the chamber until it was 20 thou larger or send the reamer back to get recut.

Should the reamer be cut with any special considerations to this possible issue?

Any thoughts on this would be appreciated.
 
OK,

The die you already have.... how much bigger than a virgin factory case is it? I know this is hard to figger but it's key. The die needs to be at least .003 (I prefer .005 or even .007) larger than the base of the case to avoid clicking. Clicking comes from two causes. One is a sizing die that's too close to chamber size, this Kiff can avoid. The second comes from sizing the reamer too small, to close to factory case size.

YOU CAN'T RESIZE THE CASEHEAD......... so if your existing die is "small base" or even typical "minimum SAAMI spec" you'll probably end up with a click IMO. This gets into a funny circular logic situation where people keep making smaller and smaller dies trying to solve the problem which originates from the stuff being TOO SMALL in the first place! YOU CAN'T RESIZE THE CASEHEAD!

To avoid the click you must set your chamber spec large enough that once the casehead expands a little (normal) it will still clear, not click.

If your die is large enough then you can have Kiff build your reamer off it.

YES, from the sounds of it Gene made his apparatus too tight. I've had several guns built by leading 'smiths which were similarly too tight...... Benchrest Gunsmith's are completely gaga over close tolerances :) feeling that "closer is better"...... I've known of BR actions built to such close spec that they lose function on a cold day....... handmade custom actions, $12-1400.00 actions, and they need to be slobbered with lapping compound and wallered out to make them work......and the mistake of building chambering reamers only a few thou over unfired case dimensions will take YEARS to get over because it seems so cool....

Sooooo, as long as your existing die is LARGE ENOUGH you will have no problems having Kiff use it to establish specs.

To be safe you might want to polish a couple thou out of your die BEFORE sending it off to Dave.......

pita I know, but in this case the correct sizing details are not automatic, not "in place" and working.... even in the world of PPC. Some of the chamber/die combos being sold as complete packages by top-name gunsmiths will click.....


sucks

Thanks Al

I will keep that in mind.
So what would be the best possible method to try and measure the base of the die? If memory serves me right I am pretty sure it is not a small base die as I did not specify when I ordered one.

I use a product from Brownell's called Cerrosafe. It's a metal with a low melting point and repeatable shrinkage characteristics.

Die makers have long known what the shrinkage characteristic of cerrosafe safe are and know what to take into account when using this pattern to add to the the die or reamer or the final product.
