Just purchased Berry's Thick Plated 165 gr bullets will be using either Power Pistol or Blue Dot, any thoughts on a powder charge? thanks. These will be shot through a stock gen4 20.

I have loaded different 165s, but Berry's are different bullet types. They recommend loads that max out at mid ranges for jacket bullet data -- except for thick plated bullets. They don't get any more specific.

My approach would be to gather a cross section of different book data and find a sensible starting load based upon the various books. That would probably be in the high nines for Blue Dot. From there, work up to find what works in your gun.

Even though these are thicker plated, I would not be overly agressive pushing to book maxes.

Sorry to not be more specific, but there is only one process to find out what works in your gun.

Thanks for posting your results. I am curious if you tested for groups on paper.

By the way, you are WAY warmer there than we are here. In the 30s here and the nearby hills are getting snow. Brrrrr.

I was just testing for vel. but the shots did hit within the paper plate at 25yds. Forecast for the weekend is highs in the 40's BTW my wife is becoming a top shot with the 10-22. The 'Tech-Sights' are a great improvement over the factory sights.
