Greetings all! Been away for awhile as my last email was hacked by some losers, so I have returned with my usual nearly impossible to answer post, but hopefully SOMEONE out there may at least have an idea on this. I have a Model 11 Hog Hunter from Savage Arms chambered in .223 Rem. This rifle is a bolt action and has a 20" barrel with a 1X9 twist rate. I am loading 52 grain Sierra HPBT on "mutt" brass and plan on using Hogdon's Benchmark as the juice. I have taken several readings with the Hornady OAL guage and have a OAL of 2.020" measured at the Ogive using a comparator. If you are still awake, I would like to know how much "jump" to the rifling should I use for best accuracy at 100 yards? I would like to start with .20 since that would give me a nice even number to set up my Lee seating die to. Does anyone have any recommendations for this load and this gun regarding the jump? Thanks very much for any advice.
