Your lucky day, I have both. And a big soap box to go with it (of course).
Gerard Tri Trimmer all the way! (sung to the tune of Jingle Bells of course)
Ok, the in depth. The only reason I got the Trim it II was that Gerard much to my annoyance (and they have good reason I guess as they are a common shoulder setup to other calibers and it keeps the inventory needs down) is they did not make it in 7.5 Swiss.
Trim it II does the same job pretty much as well as I can tell as the Gerard. Where its issue is that it does not come pre set and it has like FIVE different hex screw adjustments, sheese. I got it set and hope never to have to do it again, couple hours fiddling.
Now the real key to these (and to my everlasting shame how long it took) was DO NOT USE A HAND DRILL AND DO IT HAND TO HAND!!!!!!!!!!!!!!)
My brother got the motorized Gerard, its worth it if you do more than 4 calibers (maybe)
What I did as I trim a lot and my hands are a bit arthritis was to take my old Milwaukee (I was born in Milwaukee!) half inch monster corded drill, turned it upside down, and clamped it into my vice!
Wallaa!!! You have a motorized Gerard at no extra cost (you can do the same with the cordless drill but the shells are more delicate so you have to be very careful and I have the old metal hulled Milwaukee I don't use much so........................
Gerard you want to do what Unclenick suggested and over trim a bit is one easy adjustment. I did on 308 and 30-06 (different shoulders different units)
Trim it II I left as I set it which was a bit short anyway.
If you have an old drill that is great, mine hangs on a hook above the bench just for that use (the new cordless drills are so powerful unless its a really big job the Milwaukee is not needed)
The only reason I say 4 calibers is that at that point the cost of the Tri Trimers exceeds the cost of the Gerard Motorized setup (which is nice but the upside down vice clamped setup is every bit as good and takes up less space)
I can crank out 300 cases in under 30 minutes easily.
No reason you could not go past the 4, and they do change out quicker than the motorized Geard base unit though if you get the full setups for the Motorized (lower cost inserts than the Tri Trimmer ) that is pretty fast, just not as fast.
Gerard provided a trimmed case for the caliber of the Tri Trimmer you ordered.
Trim it II does not.
