I haven’t shot my 300WM enough to need to trim the brass yet. Looking at your pics it reminds me that I need to buy the motor for my RCBS trimmer so I don’t wear my hand out cranking by hand.

Well, after seeing the cost of upgrading to the electric motor I know I won’t be doing the upgrade. I’ll just have to stick with hand power.

Get this WFT-2 World Finest Trimmer 2. I have it and have insert for 223, 30-06 and 300WM. It does 1-way cut. It very consistent and when you use with a slow speed drill/screwdriver it works great. Less than $100 investment.

That's a cool trimmer! It's also interesting that virgin brass was 5-thou' over...

My uncle swears by his World's Finest Trimmer by Little Crow Gunworks. I got one for .300 Blackout and found that it's phenomenal for longer cases that you can hold well.

One question for belted magnums in general: how do you address case head stretch and move the belt back? I think there a guy who sells a tool, but it looked complicated and expensive. One of the main reasons that I shoot a .300 WSM, and probably the main advantage vs .300 WM, is no belt.

I have the willy's magnum belt resizer. It is like $100 shipped. It is very hard to use, but it should help for some cases with above the belt expansion. On latest batch shown above, the belt itself was expanded. I queried online and I was informed, it could be because of the chamber of my rifle. If the cases can be chambered correctly, all are good.

Here is my test for latest batch with belt itself would not fit the case.
