Did some loads with R-33 and Barnes 127 LRX. I was just looking for max and found it with 72 gr. with Nosler brass and Fed 215GM primers. This load was going 3387 fps with sticky bolt lift. I also had another 264 with me that takes more powder to get it going so I had 1 round with 72 gr. and 2 rounds with 73 gr. The 2nd rifle has a 24" barrel and the first has a 27". 72 Gr. from # 2 went 2839 fps and 73 went 2885. These 3 shots showed no pressure signs. The fps difference between the rifles with the 72 gr. load was a whopping 548 fps.
I've got a 264 that gets up to speed with about 4-5 grains lower that book. One is a tight barrel and one is a loose barrel, I suspect. That is a HUGE spread though.
Found and bought some Re-33 a few months ago. Was thrilled at the velocities I was getting under a Interbond 129 but I can't get them to group. At all (M70 SG). So, am going to stick with Re-33 but move to the NAB 130.
