First let me say hello all and thank you. I have been lurking here for quite some time and the wealth of imformation has helped me a ton. I am not new to hunting znd shooting but have just got into this long range thing over the last few years.
What im trying to do is build a good huntin load that will hold sub moa groups out to 1000.
My rifle was just a model 700 sps plain janer..... I bought the sendero barrell off here,bought a B and C stock and skim beded the action. Factory trigger has been done as well.
All my brass has been match prepped..... I have heard this dont make any difference on a factory chamber but I had fun learning and doing it haha.
Load is rem brass match prepped cci 250 3.03 to ogive. Berger 210
So my question for you guys is how would you interpret this target. It was shot at 100 yards. The 91.5 grain retumbo load looks good but the vertical has me concerned..... Also the 93 grain load looks good minus the flyer but its possible i pulled it.
The two at 88.5 were foulers. The bottom right was the new 215 berger hybrid. It was 91.5 retumbo and had sticky bolts so way to hot. Im just gonna focus on the 210 for now and leave the 215 for next time.

Reason: Forgot to add bullet to load combo
Shoot the 91.5, maybe try fed 215 primers to see if it may help lower spreads. Could also play a bit with seating depth in .005" increments to see if you can fine tune any more, but it looks good. If this doesn't help just shoot the load as it is and see how it performs further out...good luck
I would increase the distance to min. 300 yards and re shoot. Also are you shooting all 3 rounds of the same load at a time then moving to the next charge? If so I would only shoot the first round of each charge, then the second round of each charge, then the last round. Marking each shot and allowing barrel to cook between shots. Takes a little more time, but well worth the info gained.
Yes, I fired each charge weight as a group with the exception of the 4rth shot on the 91.5 grain load. That particular peice of brass was sticky in my shell holder on the press. It was the lowest shot in the group.
So move to 300 and retest all 4 charges?...... I have some 215 m primers I can test aswell. The reson for using the cci was I had much better spreads in my old load using ccis. But that was with us869 and this new barrel doesnt seem to like that stuff at all.
Its been a hell of a journey just getting this far but I can almost see light at the end of the tunnel I hope haha...
All 4 shoot well enough I'd do em all just like Mikieddem said, round robin style letting the barrel cool between shots. I'm betting in the end you'll go with the lowest ES
Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.
