What's the possibility that the Berry's bullet as the problem source for your gun as Berry's diameter .356." Lyman 49th, p338, 340 speak to the new industry standard using .355." Because of chamber restrictions, they don't recommend larger than .355." The assumption is, they mean ie fmj, etc, not lead or plated lead for that .355" number. But if the barrel tolerance for your gun is a bit snug, who knows. Another person might have the same gun that shoots it ok. Just never know w/ lighter caliber auto's. Just punting here for another thought.

Here is a string for Berry's (in 9mm), but some of the comments may apply.

Berrry doesn't have a lot of load data:

ie: Other than the data from Western and Accurate for the 9mm, .40S&W and Hodgdon .40S&W there is no printed data available.
