Re: Bullett weight ??????
I'm shooting a 300 WSM and soon to be shooting a 300 RUM, so I have been looking at the bullet selection out there and there is a good bit to choose from.
If you have the time and motivation, I would recomend trying a variety of bullets and see which shoots the best out of your rifle. My favorites for short to mid range shooting would be with monometals or bonded bullets Like the E-Tips, TTSX's, AB's, etc.
If I were to choose between the Bergers, I would start with the 210 and 190 and see which shot the best. If the same, I would probably go with the 210's because they have a higher BC. They will also be slower with more mass which helps to mitigate the fact that they are a highly frangible bullet and are likely to retain more mass while penetratiing. I would tend to favor the Berger 190 over the 185 because it has a slightly more efficient BC than the 185 and once again a little more mas.
JLK also make some VLDs similar to the Bergers.
Just my $.02
