Agree. The rifle needs to warm up but so does the shooter.

And you need to compare apples to apples. Bullet profiles are way different, right? Compare the jump to the lands for the S&B's and your own loads....not to mention the angle of the bullets where they hit the lands. I would think a factory load with bullets similar to your reloads and similar jump distance, would be a better test.
I'm no best rest shooter, but it seems to me you have lots a variables.....too many. I would try to lessen the number and maybe something will show up as the cause.
You say you want to stay with Hornady.....fine, that's a variable though, and it wouldn't hurt to try something else once.....say Sierras, or hell, even Remingtons, just to see if the ugly flyer that your S&B's don't have, shows up as usual. But that would be my second change.
If I was in the same predicament, I'd probably change the COAL first, then the bullet......then the other factors one by one perhaps starting with burn rate. Goes without saying that you treat the factories the same as the reloads.....(even the runs to the truck for example)

Try one of those battery powered mattress inflation pumps. They have a nipple that works well.
Getting up and down from behind the rifle can easily cause that problem even though I still think your rifle doesn't like the eld at the current seating depth.
I’m going to try That thank you sir
Lol apparently not very well lol

I'll ask again, FWIW, do you get in the truck with a/c on high with the rifle wait 15 minutes then you shoot the first shot or only after the first shot?
Lol it takes 10 minutes to get there I shoot and get back in the truck with the a/c on for 15 minutes to cool the barrel then get out shoot and get back in the truck until I have shot all 5 rounds
Something else nobody has considered, if we're shooting 5 round groups, how do we know it's the first shot and not the 6th shot?
Kidding aside, I agree this is likely depth and MAYBE slightly bangswitch related.

Another question on seating depth I DO NOT HAVE A WAY TO CHECK SEATING DEPTH WITH A GUAGE another reloader told me to seat the bullet in a empty brass and keep seating it till the bolt was easy to close then seat .10 deeper is this correct?

This is a Hornday L&L OAL gage with a modified case, for sale cheap at most Sportsman wharehouse (Google)Look up smoking bullets, sharpie the bullet, then seat at mag length, close the bolt, slowly and carefully extract, if you see the rifling marks, you're into the lands, if you don't, you pull the bullet out a little farther (after re-marking) and try again. Once you find the lands, you can start deciding how far off the lands, berger has a process for this, but essentially, pick a mid charge, load .005 .001 .0015 .0020 .0025 off the lands (5 each) and see what groups best, then with this coal, work up your powder charges.

I’m guilty !
Yes I said it I’m guilty of giving advice on this thread without understanding the OP shooting style or set up.
Best intentions are there however it’s nearly impossible to correct fliers without the question- what is your setup?
Hells Bells a fella could be shootin off hand after climbin a mountain then say I can’t put two bullets in the same hole at 200 yards ‘ what’s wrong?
Anywho apologies to the OP I’m out

Several things can cause a first shot flier.Yes,a cold barrel possibly can,also a clean barrel can.I have a couple of rifles that are accurate enough to allow me to experiment a little.The worst first shot variation will usually be when the barrel has been shot and put away without cleaning.The powder residue and copper from the bullet jackets both oxidize.In other words,the barrel is fouled with dry,chalky compounds that increase friction and pressure.My 223 bolt gun usually stays in the .4's.If I take it out to shoot it with a clean bore,the first shot is always right in the group.If I put it away without cleaning it and get it out again a month later,the first shot will be a little high.I have seen this with a lot of rifles.
I have that part what do I need to buy for a certain caliber? I looked on MidwayUSA and I wasn’t sure what all I needed as far as the 6.5 creedmoor I’m pretty sure I’m just going to take the scope off and sell it I have my .270win I feel it out performs the 6.5 anyway I’m not going to shoot over 400 yards if I am at all and it’s too heavy for the girls to carry
Modified case for the respective chambering (I.e. 6.5 c)
