Re: Effective Range of 257 Weatherby mag.
In the past I would not put a Barnes bullet in my rifle. Tried them years ago and I couldn't hit the broad side of a barn from in the barn. Accuracy was horendous and they had problems opening up at lower velocities. With the ttsx I shoot now in several calibers the accuracy is as good or better than any bullet on the market and the performance on game is also best. Every bullet is exact weight so I don't even weigh them out any more into groups like I have to with all the others. Also the bc's are coming in way higher in some instances from posted bc's. I never trust company bc's so always do drop tests and shoot over two calibrated chrono's. Ten years ago I was giving barnes grief over their bullets. Now I am their biggest fan. Just last hunting season I shot grizzly, dall sheep, caribou, elk, deer and antelope all with perfect bullet performance.
I have never hunted with the lazzeroni but had guys come by my range shooting them. I have quite a few 7mm's that I really like to hunt with. My favorites are the 7mm STW and 7mm-300 wby. I like the 7mm dakota but already had so many when it came out I just stick to the ones I have. The lazzeroni gave great ballistics on my range.
Predictions are difficult, especially when they involve the future
