Quick load request

Quick question for a generous soul with access to quick load;
making a final decision on a rebarrel for a nula, trying to decide which caliber. The barrel has been purchased and is a 22" 1-8" twist Douglas premium. Plan on only shooting barnes 145 and 168 lrx. Can someone please run 4 trials? I can't find apples to apples comparisons out there in all of my searching.

280ai with 40 deg shoulder with barnes 145lrx and 168lrx. h4831sc, fed210 primers, 2.525 trim length nosler brass, coal 3.335. .050" jump to lands.

284 shehane with barnes 145lrx and 168lrx, Lapua brass, h4350, fed gm210m primers, coal 145lrx 3.1274 jump for 145lrx .22. Coal 168lrx 3.2974 jump for 168 .050"

I was hoping loading the shehane longer would overtake the case capacity lost to the copper monos in the 280ai as far as performance but since I'll probably be shooting mostly 145lrx and need speed for maybe 600 yard max range to expand them, I'm guessing 280ai may be a fair bit faster. I think the shehane would edge it out if I was using heavy Berger's but I'm restricted to monos.
I sure appreciate any help that anyone can give!

280 AI 145 lrx = 63gr max (workup to verify) 3024fps 104.9% fill 97% burnt

280 AI 168 lrx = 60gr max 2835fps 102% fill 98% burnt

I don't see the 284 shehane. Only 284 Jamison?

Thanks so much! I really appreciate it! Do you mind check8ng 284 win instead of shehane?

Need water capacity of the Shehane brass

68.83g for shehane should be good

Just ;role dat buying quick load. It is sold on CD? Is this right or can you download it somewhere? 2022 should be the end of CD's!!

I plan on picking it up this month, but I'm overdue to make my decision unfortunately. I had been dragging my feet because I run a Mac and have no idea how to set up a partition to run it properly. My fault, the cost is quickly offset by saving bullets and powder. Faster than ever these days

Mac here too...

I ran it for 284 Win 68.83gr H2O. H4831SC correct?

Awesome thanks! I wasn't sure about h4831sc so was going to run it with h4350 sorry I didn't write that well in the original post.

Ah wait sorry again, the 68.83g case capacity was for the shehane, I think 284 win is 66g

Ok. Ran it for a 66gr H2O 284 Win H4350
