Minimum Load Ratio Question
Posted: Fri Dec 27, 2019 3:05 am
Hi all , Hope you had a good Xmas
I am looking at Sub loads with XTP 300 and will use Trail Boss as easy to get in Oz, i was having a look through the ADI handloading guide the other day when doing some 308 loads for Lithgow LA102 and i noticed that they list a sub 308 load using 8 grains of ADI AS30N with 168 Sie HPTP 1060fpt 26800 psi. From what i can see the AS30N is a fast burning shotty powder similar to Bullseye and N310 . ( There is no mention of using filler in the ADI data )
This got me curious to know if it would work in Bushy being fairly similar capacities. I downloaded Gordons reloading tool which i guess is similar to quickload but i have never used QL so cant say , anyhow i was pretty impressed with it for free.
I had a play with this using N310 which was on there data list and 300XTP using 8 gr N310 , COL 2.000'', said it would give VL 1083fps, 100% burn and a 40.9 % Load Ratio. Now this is the bit where i am totally inexperienced - What is the lowest recommended min case capacity % as general rule of thumb and does the rifle potentially blow up from a stuck bullet or similar.
Rifle is 110 savage bolt 18'' Barrel 450
Any thoughts appreciated
Cheers
Rob
