New to the foru

[CERJ]

Shadow,
Thanks
I am using the Lyman 4 die set, with the taper crimp as a separate last step.
One thing that was different, the round that had the issue was the last one in the magazine

[RedTeam98]

Took my first 5 rounds (ever) to the range today to test my work.
Once fired Starline brass
Federal no 150 large pistol primers
Hornady 10mm 180 gn FMJ-FP
Allianz powder - power pistol
Loaded to 8.4 gn
COAL 1.26
I also measured the case following the taper crimp and it was .422
I first shot 5 rounds of Georgia Arms factory 180 gn FMJ-FP?s as a starting point, only 2 of the 5 rounds registered on the chrono ( I have some work to do on using the chrono) and they came out as:
1133
1118
I put my reloaded 5 rounds in with the following results on the chrono:
1191
1207
2 shots did not register and the last round would not feed
When I got home I measured the last round and it was 1.198 ( I have verified all rounds at 1.26 when I loaded them)
Also checked the case diameter at the crimp and it was .422
The case has some ?scratch? marks on it that look odd (not there prior to attempting to feed it in the pistol (I attached a photo)
I was using a kimber 1911 with a 5? barrel
Any thoughts on what I did wrong?

Suggest Lee Factory Crimp Die for applying any crimp !
