With the advances in bullet design and the jacketing material , the 17's probably are better now then ever before . I'm a little different then most I found a round I liked and stuck with it instead of continuing to look for other options . I just got lucky early on and found that the 55 grain Sierra game king hollow point boat tail in my 223 running at 2900 feet per second mv worked I did how ever have to change powders from IMR 4320 when I wasn't able to get it in the 80's to H335 . But then I drive the same truck for 10 years when I can because I'm so cheap I don't like to spend money on things just to see how they work I will let others do the experimenting for me and then might change if I see they have found something that works better for the same kind of job being done . And I think that is the reason behind this page so others can say what they use and be able to compare with out laying out a ton of cash to find a different option which in turn allows a lot of people to read about other options as well , while still maintain their budgets . So then in short a JOB WELL DONE guys .
