    Well, I will admit I was pretty happy with the 257 AM after my hunt yesterday morning.

    This morning I was sitting at the kitchen table checking out my freshly skinned pronghorn head, my wife just loves me for this stuff /ubbthreads/images/graemlins/grin.gif!!

    Anyway, it was about 7:30 so I got up to get my coat on to head over to the shop to get working when I looked out the kitchen window and noticed a small light colored dot moving across a hay field across our property.

    From the gate of the critter I knew it was a coyote instantly without even looking at it though the binos. Anytime I see a yote at my place its HUNTIN time!!

    Luckily for me and not for the yote, I had left everything in the truck from my pronghorn hunt so I grabbed my coat and headed out to the truck where I grabbed the rifle, rear bag rest, clip with two rounds still in it from the pronghorn hunt and the range finder.

    I crossed the fence and set the rifle up and ranged the dog. She was 1085 yards, out of reach of my drop chart but she was coming my direction quickly so I just settled in and waited until she got withing range.

    Every 20 yards or so the yote would be distracted by something, play around a bit and then continue in my direction. I was flat on my belly in 10" of alfalfa so she could not see me even if she wanted to.

    She hit the 800 yard mark and again something caught her attention so I get on the rifle and found the correct hold. She then started running again. and then jumped into an irrigation ditch and out of sight.

    I watched for several seconds but she did not appear until I caught movement 50 yards to the left of where she had disappeared into the ditch.

    I lined the rifle up on her, then ranged the dog at 735 yards. She was still trotting in the usual yote trott so I gave out a few yells to her with no response. Then finally I gave it a real loud yip and she stopped in her tracks. Took a quick reading, 719 yards and lined the big 257 AM up and let her bark.

    Instantly the response was a classic death spin when the yotes bits at the entrance wound and spins wildly. Iknew she was dead but she was spinning so fast I could not get a good idea where she was hit and then finally she pulled out of the spin and ran down the field so I could see her off side. There was a huge read spot right at the last couple ribs of the yote, and from that I knew she would not go far and within 30 yards she was down.

    I walked back to the house and drove out to see her. She was a relatively young female, 2 year old or so with a very nice pelt, to bad it had a huge exit hole. IT looked like the big 156 gr ULD took a few ribs out with it on the exit causing the large exit hole.


    I apologize for the sour look on my face!!! I am not a morning person which is a strange thing for a hunting nut!!!! I feel much better then I look in the mornings though /ubbthreads/images/graemlins/grin.gif!!

    Just thought I would share another good Montana Morning!!!

    Just another day in paradise huh? /ubbthreads/images/graemlins/smile.gif

    That’s really something when you don’t even have to go looking for them, they come to you and all you have to do is sit in the house and wait for them.

    Looks like the “little” 257 AM is ready to do some serious hunting./ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/smile.gif /ubbthreads/images/graemlins/grin.gif

    What have you got planned for tomorrow morning’s window hunt? /ubbthreads/images/graemlins/grin.gif

    Great shooting. By the looks of that long barrel you could have started swinging when that yote came within 20 yards and got her /ubbthreads/images/graemlins/ooo.gif

    I didn't realize there were still places where you could leave a gun in your truck overnight and still find the gun there in the morning. I am lucky if the truck is still there in the morning.

    I wouldn't call that a sour look, I'd say the look of a serious hunter.

    Now THAT's what I'm talkin' about /ubbthreads/images/graemlins/shocked.gif

    Is the 22AM w/the 100/107 WCprojected to do that.

    That just happens to be the almost the exact distance where the yotes, when they do, set up an watch me or set there and bark. Since I gave away my 270 I have nothing but that 2-bit 338 and its a bit much and that's a bit far for it.

    This range is exactly what the 224 Allen Mag is designed to cover and game from yotes to deer as well. For yotes it will offer +1000 yard potential easily.

    In theory that is /ubbthreads/images/graemlins/grin.gif!

    I have the reamer in shop ready to roll. Now I just need to get in a Lilja 1-7 twist and get a bit of time to build the test rifle. THis will be one of my post big game season projects along with the 338 Allen Mag and the monster 510 Allen Mag.

    But to answer your question, the 224 AM was designed to offer easy 1/2 mile reach while still not causing severe pelt damage. Again, we will see how it turns out when bullets actually start to fly.

    I tested the 100 gr ULD RBBT in a 1-8 twist 6mm-284. Got up to just shy of 3300 fps in a 30" barrel but there was not enough rotational stability to keep these bullets flying straight.

    I would suspect 200-250 fps more velocity from the 224 AM in the same length barrel but we will have to see if the bullet jacket will survive this level of performance. Alot of questions yet with this little monster. Mainly another experiment to see how far we can push that performance envelope!!!

    Contratulations on the song dog! What is this about a .510AM?? I've had it on my mind to contact you about a 50 BMG, do you have something better in the works?

    By the way, I'm still running the 338 Kahn through its paces. Getting real good results with Lapua 250s and Barnes 210 tsx's. The 210s are a little light, but they shoot good! I'm waiting on some 225s and 250 uld rbbt's from Richard. I'll let you know how they do when I get them in.
