For some reason my copy of quickload isn't loading on my comp. I want to model 308 with TAC powder, 55gr water capacity, and 175smks at 2.815" in comparison to a powder charge of 41.5 grains H4895.

I used the barrel time for the H4895 load to compare with other powder to achieve the same barrel time.

Cartridge : .308 Win. (SAAMI)
Bullet : .308, 175, Sierra HPBT MatchK 2275
Useable Case Capaci: 47.092 grain H2O = 3.058 cm³
Cartridge O.A.L. L6: 2.815 inch = 71.50 mm
Barrel Length : 22.0 inch = 558.8 mm
Predicted Data for Indicated Charges of the Following Powders.
Matching Barrel Time: 1.154 milliseconds
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 !
3 loads produced a Loading Ratio below user-defined minimum of 85%. These powders have been skipped.
