40-44g Ramshot TAC
168g Hornady A-max
CCI BR2 Primers
Ive recently done some loads for my 308 with the above powder and heads and have been getting some strange pressure signs. I started my loads from 39g - 44g as there is no load data for this combination so i went on the sierra 168g as a start point.
The cases from the beginning were really smokey around the necks as an indication of not enough pressure, the groups were crap too. As i moved up the scale the smokey cases stayed and were just as bad but i was then starting to get an indentation on the rear of the case from the ejector obv indicating over pressure.
I went up in 0.3 increments and stopped at 43.6. The groups as i say were getting a lot better but nothing to rave about. I went to my loccal gun shop on the way back and he suggested upping the load as he didnt think the case neck was expanding enough giving the low pressure readings. So i did and took a few 43. loads to the range and had great results at 300 yards, not so much at 600. Still i have the problems of dented cases and smokey necks.
I'm fairly new to reloading so any input would be great. I'm currently working on a load with H4895 and will be trying one with some VIT 150 shortly until i get something decent
Thanks in advance!
