I have a 1x10 twist remington 308 that I shoot well out to 300 with target loads using bullets like 168g Hornady amax and 175smk. Ive decided to hunt white tail this year and at a local gun show came across a good deal on 165g flat base sp speer bullets. My gun has 2 nodes with 165 and 175. My lighter load is around 2350fps and hotter load is 2600. The absolute furthest shot I would have to make would b 250 yards. Most likely closer to 100. I have had success with r-15 and imr4064. I know I have to try loads to see what the gun likes best but is there a recipe that works in everything like the fed gold match 168? Thanks ahead of time, nick.
