I have recently began competing for the first time with my rifle. I shoot a .220 swift that I have grown very comfortable with over the last few years. I shoot it at small four legged critters, and now long range varmint silhouettes. My issue is the little bullets I am limited to. Now I can push 55g vmaxs to 3800 fps, but get the best results at 3650-3680 fps depending on weather. Now when I start pushing these little laser beams put to 650 yards, any sort of gusting winds have pretty disastrous effects. I am holding 40+" inches of wind drift at 600 yards and with blustery conditions, it's a bit of a hope and a prayer the wind is constant the length of the bullet path. My solution? I am going to build a 7-08. I want a 22-24" tube, 1-9 twist (for heavier bullets) with a heavy contour. Similar to the sendero contour on my swift. From my reading, 7-08 still shines with the shorter barrel. I know I can get 2800 fps with 150ish grain bullets. I like the ballistics table, and with 7mm I have plenty of options to take game as large as elk, to 300 yards. I know the hot bullet right now is 6-6.5 mm on the little tiny cases. I also don't have the money to buy a dedicated LR rifle so I need a multi purpose gun. So now the questions, from anybody who wants to read this. I want the shorter, heavy barrel so I can pack it into the far reaches of my areas. Am k handicapping myself here? Most of what I read only shows ballistics out to 300 yards, especially with the shorter tube. Do I really lose out on that much long range proficiency by going 7mm over 6.5? i have a quote to get a krieger barrel, blueprint the action, free float and bed the action, pin the recoil lug, and flute the barrel of 1300. To get a new bolt installed it would be a little more. Price seems fair to me but Am I missing anything? I am looking for any insight I can get before I send one of my best friends off to get made up. Here is a photo, I still have the sendero type stock it came with, and a jewel varmint trigger. I bought an xps to shed about half a pound. Riding it is a vortex viper hst 4-16x44mm.
