Shooting without a chronograph is like shooting with your eyes closed.
I agree. I need to get one. Any rec's?

Thanks for the info. I am not giving up on the powder yet. Seems like it would likely be related to the bullet anyway. How do you like the Bergers? I wanted to try those some time as well.
Since you mentioned it, i thought my rifle was 1-10 but it is also kinda old. I wonder if mine has a slower twist rate also? How can I tell? Anybody know? It is a Ruger M77 old model with the tang safety. I noted when I loaded them that the BST's are really long, much longer than the Speer's that I have been loading? Hmmm.
130 gr NBT over 57.5 gr 4831sc consistently cuts ragged hole groups in my rifle.
I load for a buddy with 130 gr. Nosler Partitions in his 270 Winchester using 59.0 grs. of H4831SC and Federal Large Rifle Magnum primers. (be sure to work up when changing primers). He gets 3/4" groups at 100 yards at 3000 fps in his 22" barrel on his Remington Mountain Rifle.
H4831SC seems to be an excellent powder as would IMR4350 or H4350 with the 130 gr. bullet. I'd try a box of the Partitions or the 130 gr. Accubond and see what they do. They are great bullets!
If it won't shoot the Sierra's either I would switch to 4350 and try it. If it doesn't shoot then I would suspect something is wrong with the gun(I suspect there is). It might have a screw coming loose on a scope mount or something.
