[QUOTE="bassin93, post: 341358, member: 15314"] Update. I chronographed the 106 and 105 grains of retumbo loads and had to do a double take. The 105s ran pretty much the same as the 106 grn loads. The average of 5 shots was 3730 with an es of 25fps. I went back a week later and shot the same 105 loads and they still read 3728 or so for the several I shot but the bolt was slightly sticky. I then tried 104 grains and they ran 3708 average. Unbelievable. I then tried the 208 Amax with rutumbo and had five each loaded starting at 93 grns to 95 grns. The velocity was only 3080 with the 95 grn load, but the es was only 5fps. I got 2.18 five shot at 300yds. Not great but I need a warmer day so I'm not shaking as bad. LOL. I was hoping for around 3200 fps. I still have room to go as the pressure signs aren't there yet so I am going to try 95.5 and up till I get the velocity or the pressure. [/QUOTE]
