and I will get you back the specifics you need as far as pricing and options on these rifles and we can discuss the details more to get you the exact rifle you want to cover your goals the best.
These are very large capacity rounds so of couse they are harder on barrels then smaller capacity rounds will be.
That said, if you use the 169.5 gr ULD RBBT I would recommend you getting ahold of Jeff Bartlett at www.gibrass.com
and order in some WC872 powder. This is GREAT powder for the 270 Allen Mag with the +150 gr bullet weights.
The nice thing is Jeff is a great guy to deal with, he sells very quality powder and the best thing, 8 lb kegs run $40 each!!!
IF you buy 4 kegs the Haz shipping charge is only $5. If you buy 6 keps there is no Haz shipping. I ordered in 32 lbs of the same lot of WC872 for testing in my 257, 6.5, 270 and 7mm Allen Mag and the total cost was $188 including all shipping charges.
Thats breaks down to about $5.80 per lb of powder!!!
There are also other advantages to this powder over stick powders other then cost. It burns much cooler then modern high energy stick powders. This translates into lower bore temps which means longer barrel and throat life.
Also, being a ball powder, it is very gental to the throat of your chamber as the powder is forced through the throat under high pressure and heat. This can significantly increase throat life.
Knowing these round would be hard on throats from the start I designed, or should I say, I had Dan Lilja design barrels and twist rates specifically for these extreme performance rounds. For the 270 Allen Mag, I had Dan tool up to build 1-8 twist barrels in his great 3 groove rifling design. This system works great with big game bullets and offer extreme accuracy with high velocity and very copper fouling.
They also limit throat errosion longer then a conventional 5 or 6 groove rifling design. They are not the best system for a thin jacketed match bullet but then again at the velocity potential that the Allen Mags produce, there is no point in using the thin jacketed match bullets because more then likely they will not survive the launch speeds anyway.
The Allen Magnum chambered Extreme Sporters are a total system designed to offer the highest possible performance with the longest accuracy life potential in the rifle.
Throat life with these rounds used in the correct way and taken care of like you do correctly will easily be in the 1300 round range at least. With the 270 Allen Mag, it may well reach 1500 rounds with 3/4 moa accuracy which is still plenty for long range hunting potential.
These rounds are designed for big game hunting and as such, a 1300 round barrel life will last several lifetimes for even serious big game hunters.

To answer your questions, ULD RBBT stands for Ultra Low Drag Rebated Boattail.
The Rem 700 in any of the RUM rounds will be the absolute perfect receiver for the 270 Allen Mag rounds. No receiver modifications needed at all except to accurize to get them shooting under 1/2 moa!

Yes I used to post alot over on AR. Got into a few ******* matches with guys that did not feel logn range shooting was ethically possible so I came over here to be around like minded shooters and hunters that know full well what is totally ethically possible.
Just a matter of having the proper equipment and the ability to use it properly and more importantly, know when you should not use it!
