Well I'm back . Re#33 is awesome stuff. My 1`st loads thinking I was going to be able to shoot all the range of loads from 59grs to 63grs pushing the 105 hybrids . The directions for my chronograph says the spacing between screens is critical, if off as much as 1/16th it will mess up the readings. . My 1st shot the velocity was so high I thought there was a malfunction. So I fired a known velocity load 51grs of Re#22 produced 3340 FPS 107gr SMK . I was shocked hey there's nothing wrong with my chronograph ! Ok so 59grs of Re#33 1st shot out of 30" bbl was 3,550 ! Then 2nd shot was 3,517 Hmmm that's a wide extreme . I only loaded two rnds thinking they would be on the low side and didn't want to waste the bullets. Then I fired two more of 60grs and velocity was 3,558 and 3569 ,so now I'm really stoked ! No pressure signs what so ever and both shots were under a 1/2" at 100 yds. Then I fired 3 loads of 61grs 3,587..3589..and 3,599 BUT group opened up and very slight ejector mark . I should've stopped there.. Then I fired a 62gr load and instantly smoke started pouring out of my action I blew a primer and a huge shinny ejector mark on the case. Velocity was 3,674. So I'll be pulling a few loads. This goes to show no two chambers are alike.Tomorrow I'll start around 55grs.
