A word of caution with RL26. It won't show pressure signs in the conventional way. I was trying it in a 257Wby. Couldn't find any data anywhere. At 72.6gr all was normal, at 72.8 a slight bruise, at 73 i had to use a hammer to open the bolt. I didn't see the bruise at 72.8 until after I fired the 73. No harm done, except for those two brass that were severely stretched. Thanks to the MarkV action. Found out later that Quick Load specs that cartridge/powder/bullet combo at under 71.0 max. Had phenomenal speed, 3636fps with the 72.6gr and 117grBTSP fr Hornady. Accuracy was terrible all the way up between 1.5-2" So make sure you have data from a reputable source, or go up very very slowly, and watch very very carefully
