Got mine and tried it out this weekend...... one word....
AWESOME!
Things I noticed:
It puts a lot more torque on your fingers holding the case than my possum hollow trimmer does. I'd assume this is because there is only one cutting edge on the Tri-Way and there are four on the P-H "mill". It also takes a little longer to do the trim with the Tri-Way, you can't go nearly as fast as with the P-H.
Using the .223 Rem trim setting from Giraud, it trimmed my resized brass to 1.745". The case they included measured out at 1.750" OAL. I'm assuming this is because I may be resizing my brass a tad too much, and then lopping off some extra with the trimmer. I retracted the blades on my Tri-way so they cut my brass to 1.750". More neck tension and less trimming. I could have backed off my resizing die, but I really only shoot autoloaders, and I'm not a fan of not resizing enough.... been there, done that.
This saves me ALOT of time on brass prep and is MUCH MUCH MUCH cleaner than the P-H. Money well spent!
