.260 Rem vs .260 AI trim to length

[codyadams]

Do they have the same trim to length? Sorry, I tried searching but couldn't find it...I'm wondering if I can just get a .260 Remington Lyman E-ZEE trim pilot for this .260 AI I'm building.

It should be the same length...My .25-06 AI and .30-06 AI are the same cartridge length as the parent case.

However, the AI is bigger in diameter at the shoulder and with a sharper shoulder angle moves that shoulder forward, so it might not fit in one of those types of specific trimmers, even though the neck junction is the same dimensions. You might have to use a generic trimmer like the Lyman that I use...

Mine is the manual w/ the power adapter shaft setup, but if I had to do it all again, I would go with this...

Lyman Power Case Trimmer 9-Pilot Multi-Pack 110 Volt

Or this...

RCBS Trim Pro-2 Power Case Trimmer Kit 110 Volt

This is what I use, with an electric drill. With this trimmer, case shape doesn't matter, just neck diameter and OAL. I did find a problem...Lyman doesn't make a pilot for .260 Remington lol

If you have a bench grinder you should be able to make one yourself from a 6.5x55 pilot.

That may be exactly what happens ha ha

with the sharper shoulder of the AI you will find your brass grows much less. You may never have to trim for the life of the brass.
