[QUOTE="AZShooter, post: 833040, member: 5219"] Yes I tried it in a 7 Rem mag. Copied from my notes on RL-33: "7 Rem Mag: 24" Rem barrel, moly coated 162 A-max seated .010" into rifling. Original 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. 79 gr and up caused the OAL to lengthen over .010", enough so the cartride wouldn't fit into magazine. I can see why Alliant only mentioned a load for the 175 gr bullet" It might work with a 180 or heavier bullet but frankly it is not the best for this cartridge. It did work well and had velocity gains over retumbo or RL-25 with these: 7mm/375 with 180 hybrid 6mm-284 105 hybrid, 257 weatherby 110 accubond 300 RUM 230 gr hybrid [/QUOTE]
