In my opinion it's not stout enough. I'm only talking about 9mm here but, after shooting a bunch of 115 and 124 gr Fiocchi...I have a bunch of never impacted" bullet....25 yard range and bullets are 75% of the way to the plates...just laying I never felt anything that made we think "stop", they all seemed to have had the same felt recoil. These things were just over squib load status....with I thought, yikes...whenh seeing the bullets. Anyone else ever see thing? Maybe I got a bad lot?
