I just picked up a M1A loaded, and Im trying to find out what has worked with this rifle using R-15 and a 175 Smk. I already use this powder/bullet combo in my savage 10, and I have had very good results. My current load for my savage was 43.3 gr 175 smk and CCI BR2 primers. I was going for a m118lr copy. I would like to build a good load for this rifle using the same components if possible just to keep things simple. I will mainly be shooting steel out to about 900 yds, and if I ever go back to FL 1k. Also is the CCI BR2 seated deep ok for the M1a? I have a good supply of those. TIA
