[QUOTE="400bull, post: 259706, member: 9065"] [FONT=Times New Roman][SIZE=3]I’m fairly new to reloading and could use some advice on a new load that I am working up for my Win 270. I bought a couple boxes of Hornadys’ 130 SST hoping that these would be my bread and butter bullet for small game and deer. In the past I have tried to load everything so that the bullet is about .015” off the lands and have good results with it that way. But with the SST I have to be at lest .040” of an inch off the lands because of magazine restrictions. So the first loads I put together I backed them off an additional .040” (total .080”) off the lands to make sure I had plenty of clearance from the magazine. When I went to the range last weekend I was getting great groupings with the exception of one flier in all loads tested. The problem is I was hopping to get a little more velocity out of them then I was. My charges varied from 56 gr. of H4831SC to 60 gr. with velocities from 2700 ft/sec (56 gr. charge) to 2940 ft/sec (60 gr. charge). I was wondering if I were to redo the 60 gr. charge but very the seating depth in .010” increments how much would this change my velocity?
