Hornady Copper alloy 90gr CX

[Bassfish1952]

        I went with the 90gr because the 80 didn't have 1000ft-lb at 300yds and started at 2900fps because that is where the 90 gr has 1000ft-lbs at 300 yds. So I am hoping to start with the 2900 and work up to best for my rifle. Right now I have 50 90gr CX's to work with. If I find more then I will be able to do more.
I screwed up when I found the bullets there was more than the one box but I didn't think to buy then when I went back there was only one box left. 
I am looking for more but like you said they are hard to find.
The barrel is 24" 7.5 twist and on a cz527 action so I should get identical to what Hornady posted in a ideal world, I think

So what is the min number to each load 2900,2950,3000,3050 to decide ? Keeping in mind I need 8 rounds to take with me when I hunt

Sorry I am having a time learning how to post pictures
