[QUOTE="AZShooter, post: 870410, member: 5219"] When I got some of the first RL-33 available well over a year ago I tried it in a variety of rifles. Here is what I wrote in my documents regarding a 7 Rem mag: 7 Rem Mag: 24" Rem barrel, Win brass, Fed 215, moly coated 162 A-max seated .010" into rifling. Original accuracy load: 72 gr of Retumbo 2975 fps RL-33: starting load 76 gr vel 2837 worked up to 79 gr for vel of 3000 for very small gain over Retumbo 80 grs showed a hint of lift and a small shiny spot on casehead. I used a bullet seating comparator and noticed that even with the use of a 6" drop tube the powder was filling the case for a heavily compressed load. 79 gr and up caused the OAL to lengthen over .010", enough so the bullet wouldn't fit into magazine. I can see why Alliant only mentioned a load for the 175 gr bullet. --------------- If it is all you can get give it a try. It will work better with a 175 or 180 gr bullet. [/QUOTE]
