No they didnt send me any load data, I just read Everything I could find about the csb-5 then started at 4.0gns and worked up slowly to 4.6gn im still loading looking for the sweet spot which I think I found with this Powder, I loaded a string today with 4.8 under 124gn cast OAL 1.135 this load felt HOT but showed very little pressure sign just a little smoke chrony was 1,137fps, im using remington 1½ primers (soft) primers to warn me. I believe I will load a few with 5.0gn and 124 gn OAL 1.145 and chronograph it I will keep everyone updated. I wouldn't go any more than 5.0gns myself im happy with 1,100fps and shot very good at that velocity, felt good in my hand the best at 4.6.. just gotta be safe and work up slowly I agree I think this is gonna be a very accurate load.im glad I bought 8lbs with the same batch number. I was skeptical at first but they ain't no Powder anywere else.
 
Good to see some real-world load numbers; thanks for the update, alientrainwreck ;) There are a lot of folks finding their way with the new-to-us Spanish powder ~ CSB works well :D
