I'm sure I'm not the only one here that "started somewhere" in their quest for stretching their limits with a factory rig . . . so how many of you are there that got the long range bug but didn't have the funds to go custom, so you made do with what you have? What I'm after is some guidance/opinions on when "good" is "as good as can be expected" with regards to a factory rifle and the accuracy, seating depth and barrel length limitations that come with it. Is a 3/4" group as good as I can expect, or 1/2", or are some of you guys lucky enough to have found the right single hole mix with a factory 700? I have a bone-stock factory Rem 700 in 300 Rum and am learning the ropes of reloading and long range. I'm very green in reloading, my father-in-law has lots of reloading experience, but none with regards to precision accuracy, so we are both learning in that regard. We have been experimenting with loads for Berger 210 LRH's pushed by Retumbo with non-match grade CCI's. I was able to get 4 holes touching (linear as barrel was heating up with a 5th shot "flyer" about 1/2" away from main group) with 5/8" group at 100. Next on our list of development is switching to match grade Fed 215's and H-1000. I'm not giving up on Retumbo, just trying different things. I'll probably try the Accubonds and the Bergers with various powder increments, lots of experimenting ahead. Anyway, at what point do you guys think I'm chasing the "un-achievable" with a factory 26" SS Rem 300 RUM? Some day, I hope within 2 years, I'll be able to make the plunge into the custom world, but until then, I'll kill things within my rifle's and my own abilities.
