The cartridge is extremely flat shooting. I have owned two of them. I got rid of both of them. I do not think the bullets were designed for the higher velocities. I will also admit that I refuse to pay $30 or more for so called "premium" bullets. I shoot too much. I shot about a dozen deer with mine. I was disappointed with the results on deer. But I will admit that I prefer a 30 caliber for deer. I will also admit that one of the best, if not the best deer hunter I know swears by the 257 Wby. He has killed a bunch of deer with his. But like me, he aims for the shoulder. And he shoots the heavier bullets for caliber.
The cartridge would make a fantastic varmintround. But you said deer. I agree with the other guys about the 25-06. With current bullet design I think the 25-06 is a better choice for deer.
Guys get on me when I post badly about a particular cartridge. But I am not being paid by anyone, and I write about my own personal experience, not some one else's.
I think you should try one of these. It is a true long range caliber. But I will admit that it takes a tad bit more practice. Tom.
