I don't think its actually the Fat @$$ version Lerch. It'd be more like the bulked up, on steroids, version wouldn't it? [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/shocked.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img]

Thanks for all the info Fifty. I figured the 7MM AM would be to big for those bullets, however, I thought I would see what you thought. Can you build a 270 AM on my BAT 8.5" action? it's currently on my 6.5x284. I am really not worried about barrel life with this project, I want something that will shoot the bigger 100+grn varmint bullets to around 3700 fps to 3900 fps. I am currently waiting on parts for my 6-284 project, this rifle is going to be built around shooting 75 to 90 grn pills. I will get between 3700 fps and 3800fps with the 87grn V-Max and 3850 to 3950 with the 75grn V-max. I also have a 220 Swift and a 223, so when I go varmint hunting, I have plenty of different rifles to shoot, so I never really put to many rounds through the same rifle. I want a large magnum caliber varmint rig built and that's why I am interested in one of your Allen Mags. If you have other suggestions, please let me know. I am open to other suggestions. Does anyone else, reading this post, shoot the 270 AM. Please, let know what you guys think about my next project. Fifty, I mentioned I was probably going to build this rifle on a McMillan MBR stock, however, this is what I am thinking about in terms of specs;
1. One of your Allen Mags, possibly the 270 Allen Mag
2. BAT 8.5" action
3. Krieger 30" 1.250 straight tapper, 1-10 Twist
4. Muzzle Brake
5. McMillan A-5 stock with lead added to rear for weight and balance.
6. Jewell 2oz Trigger
7. Davidson Base with 20MOA added
8. Topped with Nightforce 5.5x22x56mm NXS
9. Estimated weight of rifle, 20 to 25 pounds (My Guess)
Let me know what you think. Thanks Kirby for your response.

How about a 458 HE..

Here are some of the ballistics
350 gr bullet up to 3500 fps
400 gr bullet up to 3300 fps
450 gr bullet up to 3100 fps

A 300 grain Hollow point should get 3700 fps.. now that would leave a mess of things.

Should probably weight it down a bitt.. say 25-30 pounds?

Sounds good, but if your into Varmit hunting, why even bother with the 270 AM, why not the 257 AM....
The 270 has more capacity than the 257, but the 257 has more powder per bore size.. also there is not a 270 (.277) bore gun on the plannet earth that can achive the long range ballistic of the 257 AM with heavy bullets...
for example... the 157 ULD can be launched at 3350 fps
the 142 ULD at 3500 fps...
the 169 ULD in the 270 AM can get 3400 fps...

Compare
270 AM 169.5 ULD 0.760 BC at 3400 fps
257 AM 142.0 ULD 0.790 BC at 3500 fps

Think about it.... one not only shoots the same bc at higher velocity, but shoot a bullet with BETTER BC at HIGHER velocity.. and WIN - WIN

Also bigger is not always better... the smaller bore gun like the 22's 24's and 25's are made for varmits, bullets are made with thinner skinned bullets in general to expand..

I'm not saying a 7mm Rem mag can't kill a coyote, but a 25-06 with 75 Vmax or 85 BT's will not just punch a strait .284 hole through it.. they will enter with a .257 hole and depending on bullet either expand and turn the insides into hamberger, or exit with a nice 4-5 inch hole....

Don't get me wrong, I'd not turn down a 270 AM rifle, but if you are looking at the most from the best. I'd opt for a smaller bore.
The 257 AM is just Amazing... a 0.790 BC... Thats about 0.800 BC at 3500 fps.... Nothing can touch it, not even the 338-416 imp 338-408 imp.. That is a whole lot of Ballistic Drag Efficiency, at damn near (180 fps dif) 22-250 factory velocities (55 @ 3680 fps)

also I would not hesitate to use Kirby's services, unlike some (I'm not talking down about the other smiths on this board) of other gun smiths who will not talk to you about the technical side of things and more or less have the attitude of take it or leave it, Kirby has nothing to hide and will tell you what works and what doesn't and will aswer all your questions.
