Very true. By the time I got fairly close to "max" with 2015BR, Data 2200 and 2700 I was seeing flattened primers. Excellent powders and I use them quite a bit with very good results, but be very careful working up loads. Of course we all should anyway!They have a very nice hard copy for like $2.99 for sure... I load TAC in .233 so I keep a copy on my tablet... Some of their loads are pretty hot though...
Ever try 24.5 , the old markm load shoots pretty good with 55gr fmj....I’ve pushed tac to the limits in 5.56 loads based on their data. Incredible speeds from a 16” barrel but as with a lot of cartridges the accuracy node was much lower.
