I set this at 65K psi, which is the SAAMI standard.
Code:
Cartridge : .270 Win. (SAAMI)
Bullet : .277, 150, Swift A-Frame SS
Useable Case Capaci: 60.436 grain H2O = 3.924 cm³
Cartridge O.A.L. L6: 3.340 inch = 84.84 mm
Barrel Length : 24.0 inch = 609.6 mm
Powder : Alliant Reloder-25
Predicted data by increasing and decreasing the given charge,
incremented in steps of 1.0% of nominal charge.

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 64250 psi, or 442 MPa
or a maximum loading ratio or filling of 112 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
USE ONLY FOR COMPARISON !
21 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.

Thank you sir! I have not tried them in a .270, and was wondering what they would do in a 24". Seems they do pretty awesome! ha I was so surprised when I was able to get 2750 with the 165 AF in my SILs 22" 308, 2000MR was the fuel. Those are the only AF experience I have, none on game, but I like them. thank you sir!

The A-Frame has served me well in a variety of cartridges. They are robust, dropping game with authority.
Those Swift A-Frames don’t get a bunch of press nowadays but man, they have been accurate and seemed to always look great in the jugs with the few I’ve monkeyed with. Pretty robust bullet. I’d bet a 150 Swift up around 3000 would act pretty much like a 7 Rem with a 160 at the same speed and probably be an easier to carry package.
