I read through this thread 2 times.
I'll probably **** people off.
Here's my 2 cents.
First off I'm throwing the B.S. flag on Bob Becks plug for Berger bullets as the ONLY bullet for 50-1000 yard shots.
Yes I've had personal, first hand, experience with this.
Having said that the majority of my rifles have been switched to the Hornady ELD line of bullets. So far I'm impressed with them.
Now to the header of this thread.
195's vs.215's.
I would go with the 215's if your stuck on Berger.
Reason being that the 195's can be unpredictable if extra measures aren't taken. Such as opening up the hollow point cavities to allow expansion to take place. Yes I've had them pin hole through before. If A #60 drill bit is used with a pin vise to open and verifying the cavity they open reliably.
215's are seat and shoot. No special work needed.
Just my 2 cents
