Did you try using some loktite?
.016" seems a little extreme but I have to add the .016" before I start by trimming .033" from a 280 Remington case.

The 280 Remington case is helpful when determining the length of the chamber from the end of the neck to the bolt face; I should say the 280 Remington case is helpful to me when determining the length of the chamber.

I am not the worlds greatest cook (usually don't use locktite either) and granted I don't have transfers and standards.

But I can follow a recipe. This is from the Gerard Tri Trimmer manual

Quote:
This tool is intended for
use with full length resized cartridge cases
I should have made it clear, I don't do anything but full re-size.

If anyone is interested in the whole manual on the Tri Trimmer, this is the link.

http://www.giraudtool.com/uploads/8/...ay_trimmer.pdf

Some detail about not trimming with a non resized fired case or only a neck sized case as it does not work correctly.

Oh and it comes with a fired and resized and trimmed case.

I took my die apart and the resizing die expander button measures at .271. I am guessing this is where my problems are coming from. If anyone reloads 270, uses full length sizing dies and could confirm I would be grateful.

I have three different brand .270 sizing dies. The expanders on a RCBS and a Bonanza measure .275. The expander on a SAECO measures about .276. So it would appear your .271 is a bit undersize. That of course would explain the trouble with the pilots sticking tightly in the case mouths.

Ask RCBS to send you another .270 sizing die stem and expander, or even a new sizing die.

measure your pilot to. .271 case mouth wont fit on a .275 pilot. that's .004 press fit.

size a case and measure the inside diameter of the neck. a .271 diameter neck should not fit on a .273 pilot

my cases get snug on the pilot because of the burr on the inside of the neck from trimming. I trim it a little back the case off the pilot then finish trimming it.

So I called RCBS and told the guy on the other end of the line the .271 diameter of the expander ball on my sizing die. He told me that it was .005 too small. He got my address and is sending me a new one in the mail. Great customer service and should fix my trimming problems for my 270. Thanks to everyone who gave suggestions and insight. This really is a helpful place.

RCBS is great in taking care of things like that. I rarely need to call them but when I have over a small part they usually send me a couple replacements for free. Every manufacturer is going to have the occasionally out of spec part, and great customer service like that goes a long ways to making it OK. Most reloading companies have better than average customer service.
