This is my 1st post on this forum & I`m very pleased to be a part of it.
I have a .308 rifle which I use mainly for pig shooting & culling roos. I have fiddled around with reduced loads using the Lee 150gn gas checked cast slug.
The slugs are sized to .308, however I can`t get much better than about 4-5" moa, often worse. I`ve spoken to the boffins at my Australian powder factory - ADI.
(ADI is marketed in the USA as Hodgen powders)
They told me to start with the fastest powder they make, AP-30 & use 10gns working slowly upward.
I`m up to 12.5gns so far & no improvement. I am concerned with such a fast powder I`m veering towards some very high pressures, although none are evident yet through visual inspection of primers, cases or sticky extraction.
Accuracy is, as I stated quite poor. The above mentioned powder is close in burn rate to Winchesters fine 231 or Uniques bullseye.
What powder should I be using from the Hodgen lineup ?
Can anyone give me a sensible starting point with powder weights ?
Ideally I`d like to get up around the 1800 fps mark or better, or am I just being over ambitious here ?
Thanks in advance for any replies
