303 Epps reloading data

[treeman]

hi ! - I am wanting to see other folks reloading data for the Epps in .303, I have always found it more pleasant to do my load development along side someone else's experiences - nice to build the bigger picture.
I only have S365 to load with at present, but part of this post is to have other reloaders experiences with import propellants.
I am loading a 174 gr bullet at 77.8 mm CTL S365 at 51.6 gr for 2630 fps at present - its a 107 % compressed load.

[tripodmvr]

Cartridge : .303 Epps Imp.
Bullet : .311, 174, APM 174
Useable Case Capaci: 56.487 grain H2O = 3.668 cm³
Cartridge O.A.L. L6: 3.063 inch = 77.80 mm
Barrel Length : 22.4 inch = 570.0 mm

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 55000 psi, or 379 MPa
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 !

64 loads produced a Loading Ratio below user-defined minimum of 90%. These powders have been skipped.
