Just picked up a batch of Lehigh 330 grain Bore Riders and getting ready to do load development for that. I am hoping to get 3250-3300 out of them and run them as my "nuclear" load. I will post results once I find a load.
pictured on top of a 7 SAUM case just for photo purposes. I am hoping to get atleast another 100 fps out of these, I was getting 3150 out of the SMK's with out pushing too hard, I am hoping for atleast 3250 with this projectile in my setup. I am thinking of a starting load of 135 grains and going up from there.
Here is my initial test, looks very promising. I got 3269 for max, 3248 min, 3259 average with 136 grains of H-1000. (I got 3292 with 138 grains, but not gonna push it that hard) That 136 load with an SD of 8.7 over 7 rounds looks like it will play if I can find a seating depth that shoots.
Running numbers it will have 4040 ft/lbs of energy and stay supersonic to 2500 yards at our normal ELR spot. I am excited about this bullet if I can get it to shoot well!
100 yard group, nothing to write home about, but I figured I would put it on paper while shooting over chrono. Probably will do actual group testing at 500 yards once I continue the testing.
Low shot was a yank too, I felt it as soon as it broke.
Here is a shot of the high end of the speed with 138 grains, that is shot number 3, I deleted it from the string, just wanted to see what that load would do for speed.
decided for multiple reasons not to try and push it that hard, but I had to try one to see what it looked like.
