doogan Report post Posted June 22, 2015 You don't mention what caliber you are loading for, but RL-33 could be a great alternative for the bigger magnums like the 300 RUM or the 338 Lapua. It meters similar to Retumbo and generally gives better velocity. And unlike the other RL powders, it has not shown much sensitivity to temperature. I am currently using it in both calibers mentioned above. Reloading for a 300 RUM. Never tried RL 33, has anyone used it with any success? Curious now, any recipes? Shooting a 210 Hunting VLD. Thanks guys Share this post Link to post Share on other sites
