Guys, I'm thinking about building a gun. Because who doesn't want a nice gun in their safe? Anyway, I've been researching, talking to a bunch of my customers that shoot. I had a conversation w/ my taxidermist. I mentioned that I was considering the 300 Win Mag. He mentioned the term BC and how I should take that into consideration before I choose a caliber. I understand the concept. Basically, Some bullets fly better than others. Makes perfect sense to me. Well he's a big fan of his Rem 7MM. He has a custom gun and the gun(his whole family uses it) has over 20 elk kills w/10 or 12 of them being over 500 yds. He explained to me that he shoots his w/ 180 gr Bergers at about 3020fps. His bullet has a higher BC than a simular 180 in 300 Win Mag. Even though the 300 win starts out faster than his 7MM, his berger's actually catch up to the 300 Win and at 500 yds his bullet has more energy left because of it's BC. Basically he said his setup shoots flatter w/ the same size bullet. This sounded plausible to me. I asked him where he got this info from. He said the guys at Gunwerks gave him the details. I even called his gunsmith and he said the same thing although he also said that I couldn't go wrong w/ either caliber. Is this the real deal? Hard to argue w/ success. If so, I may have to look at the 7mm's. I'm not a huge fan of recoil so a gun that's a killer AND enjoyable to shoot would be a plus in my book.
