Go for GM!

I think the 10mm would Feed the 40 rounds fine but remember they headspace on the case mouth so the 40 would need to be held by the extractor to be able to fire. Same as shooting a 9mm in a 38 super. Some people say they work fine, others say not so good.

Just a FYI, if you have large hands this button will dig into your weak hand and you may drop the mag unintentionally.

It's all about having fun!!

Awesome. You're welcome.

They usually have enough material on the muzzle end of the reverse plug so you can shorten it.

From my experience trying that if you are lucky enough to get it drilled, you will probably ruin the drill bit, you will break the tap in it. Did that a couple times and gave up. The mag release is very hard.

It depends where you shoot 3 gun and if they make provisions for PCC in their 3 gun matches. You will not be able to compete with a 223 rifle if there are long range targets.

It's cold right now here in NM. It's down to 61!Brrrrrrrrrr

It might just be me but I get a bad feeling anytime I see a loaded gun pointing at me. ?

9 major also. You can just drop your load down 1 1/2-2 grains from major which will be around 140 pf depending on your powder but be aware that a lot of slower powders will be pretty dirty at reduced loads. You may also need to drop the recoil spring a couple lbs.

Working on it!?️

Thanks guys. I will be there next year!

And I will be recovering from shoulder surgery instead of shooting the match. Priceless..............?

I would think those dings and dents are a result of the brass hitting the edge of the ejection port. Possibly the extractor needs tightened up or the ejector needs adjusted.

If you put some target tape on the bottom of the mount/Cmore after you make changes it will show any new brass hits.

That is good. I haven't had very good luck with the long grain powder in the Dillon. But it does very well with ball powder.

Haha! Time flys when you're having fun.

Well let's see, I started shooting USPSA matches in the late 80's and probably shot several years before I started setting the extractors up like that. No it wasn't Major 9 back then but did the same with 38 supers. So maybe 24 years then.?

A Lee universal decapping die will work good for those.

I have not used IMR4895 with 55's but it was my most accurate load with 69 Sierra's. Only problem is it does not meter worth beans on a Dillon powder measure. I actually had squibs due to bridging in the powder measure so had to weigh each load. I have since changes to ball powders.

You are going to get opinions saying both ways are correct. I tune mine so the hook touches the groove as that will allow for maximum hook contact on the rim. Been doing this for a little while, like 25 years. ?

I've been using WSR primers for many years and have had zero problems.

Once I get through all the clutter mine is a 7.5 but until then I have to admit to a 2.5. ?

Bought a bunch of the S&B primers several years for a very good price. No issues at all with small pistol primers but the small rifle primers are too hard for a handgun.
