    I was watching Shawns video again. My wife hasn't quite got it memorized. I'm trying to help... I got to the bear section. I wasn't really paying attention. But, when Shawn shot that bear I thought, WAIT! I rewound it and watched it again. Maybe it's an optical dellusion, but that 338AM is shooting FLAT! I'm uneducated about Kirby's 338. But if that thing is shooting as flat as it looks...Holy @#$^!! That is a monster! By the way, nice shot! The consistency and wind doping skills on the video are impressive!

    There is no denying that the 338 AM is one of the top fuel dragsters of the long range world. It is quite flat shooting. On video certain optical issues happen. Long ranges usually look farther than they are. Also when watching trace going downhill it looks flatter and uphill looks like more drop even though they are the same give like angles. This optical illusion can also be effected by the height of the camera above or below the rifles bore. But in answer to your question yes it shoots flattttt.

    Also its fast!!!!

    I'm getting the timing down pretty good to stop the video at the time of impact. Even though its a longer shot ya gotta be way quicker on the button to catch that one. Also its very visibly noticeable.s h

    Seeing as how my grand son is taking over my 338RUM carry LRH rifle.............................................;)

    Roy, Sounds like you'd better get one ordered. Can't be without a 338!

    Shawn, Thanks for the informative response. I believe the AM is very flat shooting. However, it's hard to imagine it's shooting as flat as it looked. It also seemed the camera was a bit higher than the shooter, and the shot was downhill. I suspected some sort of optical illusion.

    The camera was in fact a little higher and to the left of me.

    I have not shot anything that shot flatter out to 1000 yards or farther. That said, as good as the 300 gr SMK is at 3300-3400 fps, shooting the prototype Wildcat 265 gr AT RBBT at 3500 fps is just impossible to discribe in comparision.

    Unfortunately, that bullet may not find its way to the mass market because of boarder crossing issues with componants and bullets. Very sad.

    Just imagine a .960 BC bullet at 3500 fps, and thats out of a 32" barrel!!!

    Only thing I have tested that shoots as flat to these ranges is the 7mm AM with a 200 gr ULD RBBT in a 30" barrel clipping along at 3300 fps. That said, there is no comparision on target when the 338 lands compared to the 7mm landing home. You get numb to this level of performance when you play with it all the time but when you pick up a conventional rifle with conventional bullets, it becomes very clear how potent it really is.

    Kirby,
    That's amazing long range performance. I realized the answer was on the video too. He said he dialed up 16 n 3/4 minutes. Assuming a 100 yard zero, that is amazingly flat shooting for a 300 grain hammer! Truly awesome terminal performance! I am going to have to run your numbers in xbal now.

    I'm afraid I'm catching the 338 bug. We'll have to have another chat after that 7 shows up!

    With my 338 AM using that load with the 265, I use the NP-R1 reticle for hold over set on 11x so there are 2 moa between each reference line. I have my rifle zeroed at 300 yards for my environmental conditions typical for fall big game hunting in my area.

    With that zero, a 1000 yard shot is a dead on hold on the 6th reference line down from the main crosshair(12 moa).

    With a 100 yard zero it would be just short of the 9th reference line(13.75 moa).

    The amazing thing is how quickly it gets there. There is not much recoil at all with these rifles and our slab muzzle brakes but at 1000 yards, you better have good control of the rifle to get back on target before the bullet impacts. Hard to believe but they get there FAST.

    The best thing is that your still dealing with 2600 fps and 4000 ft/lbs of energy at this range and only 2.25 moa of windage at 1K with a 10 mph cross wind. Like I said, you get SPOILED quickly with this level of performance.

    Al tipped bullets

    Kirby:

    So are you saying we need to forget about Wildcat's Al tipped bullets? That's a bummer!! Have you had a chance to test the Henson 220 .308? It's BC is supposed to be in the 0.9+ area. I'm waiting on these bullets to decide on a build.

    Thank you!

    Kirby, Please keep us posted as to how we can get that 265 grain .960 bullet. I need some of those for my 338-378's. I am shooting the 250 Hornady at 3325 fps with a BC in the mid .6 something range. I would like to get a .960 shooting out of it by elk season. How do they get .960 out of a 265 when the 300 matchking is only .768 or so? I wish you could get that 338 AM down to 12 or so pounds so I could hunt with it. The 300 fps difference between my 340 wby and 338-378 is very impressive. I couldn't imagine going up another 300 fps to your rifle. To quote Larry the Cable Guy, " That would be some fun shooting right there, I don't care who you are".

    I remember Shawn said something like 1k with the 338AM was like kicking your dog. I smiled at the time. Now I am beginning to understand!

    The long lightwieght Aluminum tip makes the 265 grain longer and more stream lined than the 300 SMK creating less air drag
