So starting off this I am fairly new to reloading for rifles. Have reloaded alot of pistol and shotgun. I have a Rem 700 SPS in 243win that I have been working up loads for. This rifle was only a mediocre shooter in its factory condition. 1 1/2 moa with most factory ammo and maybe 1 moa with some that it liked. I switched out the stock for a bergara hmr stock inletted for the Rem 700 and skim bedded the action and recoil lug and left the barrel free floating. So got all set up to reload and chose the 95gr SMK to start with over H4350 with FGMM primers and once fired hornady brass. Started out with a 300yrd ladder test in .5gr increments loaded at mag length 2.800 with about .150 of jump. The ladder test showed 41.5-42.0gr and 42.5-43.0gr had promise. So loaded up 41.5-43.0gr in .5gr steps for shooting groups. Once again most where around 1-1.5 moa at 100yrds. Not sure how to continue but not satisfied with results I loaded up 42.0 and 42.3gr but this time started .020 off the lands and worked back in .020 until I had .080 of jump. Wow the groups finally improved. 42.3 at .020 off the lands at .5 moa but the groups open back up at 0.80 jump. Only problem is the best shooters are way over mag length. So where to go from here? Do I continue backing off the lands until something else shoots well? Go all the way back to the drawing board and change to diffrent bullets or powders? I know some bullets tend to like more jump than others. I do have plans to rebarrel the rifle in the not too distant future but would like to use the remaining barrel life here to learn about reloading. Any help would be greatly appreciated.
