IMHO that's not your gun's fault
To me that looks like some bad ammo.
I have not used that brand in years so I can not say it' quality at this time.
In my GP-100 I have used a lot of WWB and what ever the range had on special....

Some real experts will be along in a while to give you a technical answer ..

Lateck,

Those look like aluminum cases which may not perform as well as brass. I have fired Winchester White Box .38+P's in our LCR but no magnum loads. I have also fired quite a bit of handloads between .38+P and full blown magnum. They have not pulled.

I suggest you try some brass case ammo and reserve the aluminum for a heavier gun.

I know this is an issue with this light weight gun so what I am interested in is some some owner experiences with different ammunitions. What stayed seated, what didnt.
Thanks,

I'd try a 125 grain .38+P in that gun. I am not a fan of snubby .357s (the metal SP101 or S@W 649 excepted). JMO, Eli
