Re: 210 gr bergers on deer.
The Berger's should be a good rockchuck and Coyote bullet, but light for deer. I might try one this coming year on a small Blacktail deer just to be sure. If I do I will be sure to have a broadside shot and have my partner, with a Sierra bullet ready to take a quick second shot. I think the 210 grainer should have enough sectional Density to finish the job regardless on a 130# deer at around 500 yards, for a test. But, only testing will tell. I would do a couple of preliminary wet packs with newspaper first though.
Working to improve hit probability.
