I agree with this 100%. It makes perfect sense and works like a charm. This is what I've been doing for a few years now. The real nice part is that PTG makes many of the die reamers for Redding, so he knows the specs by which to make the finish reamer for a custom spec'd fit. It's really no different than going the custom die route..but cheaper and on the shelf. All it takes is a phone call to Dave Kiff and he'll know what to do for most cartridges, without the need for even sending him sized or fired cases...none of that, just tell him what you want to do and if you know, how much you want the reamer to be made bigger than the die reamer was made. You get different amounts of spring back at the shoulder vs at the web area...Dave knows all of this and can make a recommendation or use your specs if you know them. As far as how the die works..it's exactly as a properly made custom die works. Just because it's not what the majority does, doesn't mean it's not just as good. IMO, it's better and just plain makes more sense.--Mikeamlevin said:I'm sure there are good arguments for custom dies but two things I notice. First, those who make them are certainly proud of their work and second, aren't in too big a hurry to produce them even when they have your payment in advance.
There are more than enough reamers to choose from so just choose one that will work with a quality die like Redding, Forster, Wilson, etc.
The difference in brass life, is easily measured, as is how much and how often you have to trim.fguffey said:Then there is always the question: Where are we going to find someone that can measure the difference? Then there is measuring the effect of a case that has been sized with my RCBS dies and a case that has been sized with a 'custom' die.

I'd venture to say that it wasn't luck. The Harrell's and Whidden are customs and the Redding works very well with a pretty wide variety of reamers. The big problems come when chamber reamers are spec'd at either the extreme large or small ends. You will very seldom see any custom chamber that are too big. That usually is seen in factory chambers. It's pretty common for people to spec BR reamers to what I consider to be too small. When you do this, a custom die is a necessity to get the brass to size down enough to avoid the dreaded bolt click. Too big, and the off the shelf die sizes too much and creates a poor fit and excessive working of the brass...contributing to considerably shorter case life and more frequent trimming. I've managed 50+ loading on Lapua cases in my br rifles, with what most would consider very hot loads. I probably could have gotten a few more out of them at that. I am fanatical about bolt click...hate it and won't tolerate it. There's a fine line that provides both good brass life and no bolt click, IME. Sure, I could shoot milder loads and get even better life, but I tend to do what the gun tells me it likes. Tuners do allow me to load down slightly and still maintain good tune. I simply load to the lower end of the upper node. IOW, I stay with a load that is ok pressure wise at any temp and maintain tune with the tuner, rather than chasing tune as the day goes on with powder charge and seating depth.zfastmalibu said:I must be lucky. I have always had good luck with Harrells, Whidden and Redding dies sizing my cases just right.
The main reason for a custom die is for making your gun operate properly and minimally size your brass. Any gun factory or not will benefit from a custom die. Now if youre talkin about a 270 you shoot only at deers and fire it 3rds/yr maybe you can get away with factory dies. Hard bolt lift and brass life is a non issue in that case.
