Re: 338 AM vs 375 AM?

What .338 is capable of launching a 325 gr. bullet at 3300 fps? And can this be done without significant overloading?

My understanding is the 338AM is a 408 Chey Tac case necked down to .338 and is more than capable of these kinds of velocities. It makes a 338 LM case beside it look small. Check out Kirby Allen's web page and you can see for yourself, he makes some pretty amazing toys that one day when the wife isn't looking I'm going to get

Send her on a shopping trip with enough money that she thinks she is getting away with something. That's my plan . . .

I am currently in Afghanistan but before I return, I am going to have my "dream rifle" built and, hopefully, have it ready when I get home. My plan is to give my wife $5k and let her have her way so I can go dump 8 or 9k on a new toy.

338 AM vs 375 AM?

My read on this is that they are both very similar with the exception of the 375 having an advantage in bullet weight. But when push comes to shove a game animal isn't going to know the difference.

The 338 may be a bit more of a barrel burner. If used as designed, for hunting only, it'll last a couple of lifetimes.

I went with the 375 AM simply because I finally got tired of "settling for" and went as big as I could imagine . . . and a 357 barrel was immediately available.

The 350 SMK @ 3250 has about the same flight time as my 270 AM shooting 170s.

Plus the Kirby built 375 AM is much more of a pleasure to shoot than my braked 338 RUM w/300s and its nice to shoot.

Mr Roy, have you tried any of the CE 375, 400, or 425gr bullets? Is 3000fps possible with the 425gr CEB?

No, and I don't know. . .

I'm pretty much over my tinkeritus as far as "trying" different bullets. Plus solid bullets give me the vapors.

The 350 SMK shoots exceptionally well and at my elevations is supersonic to 2700 yards.

I'd be wasting barrel life, powder, primers and brass simply to put better numbers on drop charts.

I'm confident, under well understood conditions and locations to 1200 yds and will by next season work up to the same level of confidence to 1500 yds hoping for a shot under 1k. The SMK will do it well if I can "make the shot."

Yes out of a 375/408 imp that is very possible

I have found basically the 350,375,400 & 425 CEB are ballistically indentical.

As the speed goes down the BC goes up.

I have shot the 350s & 425s back to back at 2050 & 2550.

The windage was only 0.1 moa different according to my ballistic calculator & the bullet strikes confirmed that.

So you can shoot which ever you or your rifle likes the most
