Wlp primers
They were moving at 1340fps through my crony 9.4g longshot gave about the same. 9.2 had no over pressure signs at all 9.4 had some scratches on the case and burr on the head were the extractor goes.
Does this velocity sound right to you guys? Overpressure?
I checked my chony with a known load and all was good.
Thanks
That load runs quite a bit slower in my G20 (1180 fps), but it is otherwise a decent load with no indications of excessive pressure.

I wonder if you mean where the ejector goes? Scratches, nicks and dings are normal. A warm load smacks into the ejector pretty hard. The case then can bang the corner of the slide on its way out. A photo or two, or at least a bit better desription of the burrs and scratches can let us know for sure.

I used 9.3gr with a CCI#300 primer and a 1.255" OAL and got around 1250fps with the stock barrel and a 22lb spring. So, you're definitely hotter with the WLP's and your lot of Longshot. You didn't mention your OAL, so that could have an effect on the velocity/pressure. The ejector burrs are normal when you've reached full power. I agree with what Taterhead said, I think it has more to do with slide velocity from hot loads than anything else.

Personally, I wouldn't go any higher with your lot of Longshot, since you are getting excellent performance where you are at. You may have to back off a little if you start seeing Glocksmiles.

I measure pressure using case head expansion. My somewhat arbitrary case head expansion limit standard had me stop at 1295fps from the stock G20 barrel, but with CCI#300 primers and my lot of Longshot. The powder charge was higher than yours.

Cool thank you guys for all the info my col is 1.250 i actually downloaded it quite a bit to 8.8g and a col of 1.255 i gotta make it out to the range here to try them. I wanted to keep the velocity under 1300fps 1240-1260 is actually what i was shooting for. I want to keep the gun stock except i have a 20lb wolff recoil spring comming in. I want to be able to shoot everything reliably.

Has anyone swapped out 180g xtp's for 180g gold dots using the same powder and charge etc... What were your findings? (I know i should always do work up.)

If you don't mind handweighing IMR800X is what Underwood is using in all of his performance 10mm cartridges.
You can read more about his loadings here; http://10mm-firearms.com/factory-10m...5155165180220/

Would I be ok with the stock barrel / recoil spring assembly, or should I get an aftermarket barrel/rsa right from the start? Im concerned about the brass smiles and havin a strong enough spring to prevent battering.
Im asking because these are max loads from the manuals, but milder than some loads ive seen suggested. Thx for the help.
It is just my opinion, but max loads I would use a fully supported aftermarket barrel. 200 gr XTP and 13.0 grains of AA#9 would smile in a Glock barrel. I never use a Glock barrel in my G20. Had too many smileys even with some factory ammo
