So first off I've never owned and have actually only shot one custom rifle. I now have 864 rounds down the pipe on my remington sendero II in 300RUM. The rifle has always treated me very well and after practice with it, and thousands of rounds (with long range learning the focus) through my .223, and 30-06 I am finally able to make confidant shots out to 700yrds (that's the point at which I no longer trust my skills to make a clean one shot kill). This past season I was four rounds fired with three kills - pronghorn on a rare non-windy day at 687 (something I am really proud of!) muley at 511 and an elk right at 550yrds and 15 degrees uphill; the elk took two shots i screwed up the wind the first shot I have most of my time behind the rum attempting to find a load that shot well. to be honest the best groups (3 shots) i have ever gotten have been right at 3" at 300yrds, however i can consistently shoot 3.5-4.5" at 300yrds. I really thought that I just was never going to be nearly as good as many of you guys out there (now I know that most people are stretching the truth a bit when they talk about their 1/2 and 1/4 moa everyday), but I had a chance to get behind a friends custom built 300rum and found myself shooting a lot better - two groups at the same 300 yrd range that were under 2" and my "largest" three shot group was 2.75". Now, I am sure that there were a few factors that led to my personal best shooting; better trigger pull, a DE break, better rifle with a better load? something else? Over the past 6 months i have been floating the idea of making a big purchase and going for a custom rifle, while saving and saving for the project. I am ready to send away a couple months mortgage payments and I really think I am leaning towards getting a .338EDGE. I am really looking for everyones suggestions of what direction to go with this build... thanks in advance!
