In fairness,my 1-7" Rock isn't pictured and I'll be shooting a new Montucky 223AI when I get home.
But you get the picture.............

Very curious to see how far Ackman will lie her way out on the limb? She's on Record pace,currently.
I bet she don't say anything about the Imaginary Rifle's particulars,because even she knows better.............. No magic and not imaginary and you know that. I've been through this before with other people......also with you. Using a different name doesn't make you clever. After more than 41000 posts, it's time you outgrew trying to be the bully. Stop with the drugs or drinking or whatever it is that fuels your bigmouth tantrums. Anyone who even cares about my "magic" "imaginary" rifle can send a PM and I'll be happy to tell them.

IO, what do you think about the 75 scirocco's out of the AI? How do they compare trajectory wise to the amax?

Their BC isn't as slick(I factor it as a .4),so they won't quite keep pace,though their integrity really is excellent.
Shoot more of them in 22-250AI................

I don't always agree with IO's delivery, but he knows exactly what he's talking about here. The throat required for a 75 A-Max vs a shorter bullet? Here's a thousand words with the 75 A-Max and the 50 V-Max seated to touch in my rifle. The mag box may require massaging to run a 75, but not the throat. As far as long range trajectory, go back and read what IO said again. In my 1-8 twist 223AI, I get 3050 with the 75 A-Max and 3600+ with the 50 V-Max. Want an education? Run those numbers in your trajectory program and see which one shoots flatter. And frangibility of the 75 A-Max? You have to see it to believe it, it will seriously mess stuff up. RickF, I don't have a ballistics program--would you mind sharing the highlights of the amax at 3050 vs the 50 vmax at 3600 comparison?

Quick and dirty, zeroed 1" high at 100 yards like a varmint rifle might be...
50 V-Max at 3600, then 75 A-Max at 3050:
300 -6" -8" 400 -19 -22 500 -42 -43 600 -80 -73 700 -140 -116 800 -227 -172 900 -348 -247 1000 -506 -345
If you jack the 50 up to 22-250 velocities and stop counting at mid-range, you can make the 50 look flatter. But you don't buy long, pointy bullets to stop shooting at 500 yards.
Anybody who seriously concerns themselves with the adequacy of a Big 7mm for anything we hunt here short of brown bear, is a dufus. They are mostly making shidt up. Crunch! Nite-nite!

It does amaze me that even WITH the pic he still couldn't figure out throating relationships with the two bullets, after me saying they were both seated to touch in the same rifle. ??
Still wondering...the 75 "requires long throating since that bullet is so long". The 75 "must be seated too deeply" and eats up all that powder space. They must think the thing is a javelin! Must be all that freebore I've got in my rifle that makes it work??

Yeppers, those are long throats. Long throats will work for a while for the 50's, but you will be stuck with the 75's after a while because the 50's will not shoot well as soon as they start to jump.
Rick, you did not plug in our velocity of 3800 for the 50's, groups in the low 2's with our 14 twist 223 AI's. In our custom 223's, we shoot the 50's at 3600 with IMI brass, 7 1/2", 26" 14 twists, N133. Rick, I design all my own reamers, fully understand throats. I was one of the very first if not the first to shoot the Hart 8" twist with the Berger 105's in 1990 at registered benchrest matches. Later, I built two 22 PPC's with 9" twists and a Benchrest custom AR with a 9" twist to try and win a $500 trophy that the NBRSA was offering to anyone that could agg a .250 in a registered match. I could agg .285 but not lower, would have gotten the trophy if Bill Wylde had put a 1-14 twist on the rifle.
If you think that I should be impressed or intimidated with those rifles, I used to order McMillens 10 at a time to get the Dealer discount. If you had 20 of them laying out there, it still would be no big deal.
If you had 50 of them laying out there, you are beginning to get into the relm of Ackman's world.
I think that we will start calling ImitatedOften, "Satin's Disciple" because he spews nothing but hate and venom.
IO, you diminish this board with all your hate.

IO, you diminish this board with all your hate. Dummy, Satin is a fabric. For conversation and because you are talking out your azz(because it's the ONLY thing you can do)...50's shoot exceptionally in a throat that kisses the 75A-Max at 2.515". If only because I have one(Factory throat too). You shoot your mouth and that's it................

Do you ever wonder what Rick Bin and his wife think of your ranting on a site they have worked hard to develop?
How about the advertisers, think they want to invest money in a site that allows posters to spew hate all over the world?

Keith, not interested in spewing venom but have a couple thoughts.
First, my rifle most assuredly doesn't have a long throat. The COL for the 75 A-Max to touch is 2.464". For the 50 V-Max, 2.313". I hope you know that difference is from the ogives. How does that compare to the COL's you like to run?
Second, I'm happy to plug in any velocity you want for your 50 grain load. But to compare apples to apples we need an equivalent velocity for the 75 A-Max. That is what I did, used velocities worked up to what appear to be similar pressures in a rifle I own. It is a 22 1/2" 8 twist. For what it's worth, that little #1 contour rifle averages about 0.4" with the 50 V-Max, and better than that with the 75 A-Max.
To compare to your 3800 fps load, we need "what?" for a speed in the 75. 3250? Work up the load and we can compare.
Anybody who seriously concerns themselves with the adequacy of a Big 7mm for anything we hunt here short of brown bear, is a dufus. They are mostly making shidt up. Crunch! Nite-nite!
