So I have not posted in a while nor have I been giving my rifle enough attention. With antelope season just around the corner I realized I have 2 loaded shells left one is a 140 AB and the other a 129 sst I am going to continue work on the 129 sst, they were showing promise and I had all the info safely stored on my phone backed up online, got a new phone and reinstalled the app and it backed up everything (NOT!!!) So I am starting over ,,,I think i was loading 66 grains of RL 22 but I can find nothing online that tells me this is close. The only thing I can find is 270 wsm and two loads on reloaders nest with 130's and 70 gr and another with 58. Does it make sense that the same case with same weight bullet weight I would be safe to work near those numbers? Thanks for any help. PS I have a magneto speed v2 on order probably wont getr here until load development is done Ill have to use the pro chrono until it arrives.
