[TheOtherMike]

I tried a few different rounds at the range yesterday.

First setup was G20SF with stock barrel and 20lb RSA at 10 yards.

Federal 180gr FMJ (didn't measure initial diameter):
- No reliability issues in 30 rounds
- I was all over the target. 3" to the right shooting LH and 3" to the left shooting RH.
- .433 dia

PPU 180gr HP (.422 initial dia):
- No reliability issues in 20 rounds
- Accuracy improving ...
- .430 - .431 dia

UW 200gr TMJ (.4215 initial dia):
- 1 FTF out of 25 rounds. Nose high, almost chambered. Was last round in a new mag in 3rd string of 5.
- On target now.
- .434 - .435 dia


Switched to KKM 6" barrel.

UW 220gr HC (.4215 initial dia):
- 1 FTF out of 15 rounds. Nose high and left. 3rd round of 5 in mag.
- Nice 2" groups. Very smokey!
- .430 - .431 dia


Switched back to stock barrel.

Armscor 180 FMJ (.421 initial dia)
- No reliability issues out of 10 rounds
- Good groups
- .435 dia

[445 supermag]

T.O.M.

looks like a nice day at the range.   Thanks for that info.

looks like ONLY UW gave you some issues. Hmmm.

but hey shooting and especially a 10mm is a great way to spend a day.
