Yea sorry I guees I left some info out
1686 nosler BT with 43.2 grs of rl15
Tried bumping it up but the hotter I got the worse teh gruops got.
I have tried several powders and I just got my hands on a pound of cfe223 so Ill try that out this week end
RCPO, I just recently bought a Browning A-bolt II in 308Win and I looked at the manual data and thought I would try some IMR4064 with Speer 165BTSP in Win brass. I started 1 grain over the listed start load and worked up in .5 grain increments with 4 rounds at each charge weight. My start load was the only load that showed any promise at all. I was shooting in a moderate cross wind and pulled on shot and it was 1/2" left of the other three which went through one ragged hole. I am pleased with the accuracy, and though I didn't run these over a chronograph I know they have to be on the slow side of velocity. I don't think I am going to fret over the speed as I don't plan on shooting at extreme long range with this caliber. I chose 4064 because it was shown to be able to reach the higher velocities while keeping the pressure in check! Yeah, whatever....
We have tried several differant loads. I say we because my shooting buddy is working on a new 308 as well We both picked several powders and then pooled our test loads. I want to try the CFE 223 just cause (im also going to try it in my 223)
It seams like most of my loads are a bit slow but I dont push it to the hot side either.
If it shoots good I use it Thats what really counts not speed. he is using a differsant powder(cant rember which) and getting about 200 fps more.
So far we both have good dope to 700 yards now we need to go and scare the rock chucks
The good news is that with RL15 and a 168gr bullet you are pretty unlikely to get into a pressure situation... RL15 really is one of those 308 powders that go dang near perfect with 168 / 175 gr bullets. I would cautiously push the loads up with RL15 on that grain bullet as there is usually a LOW node for accuracy and an UPPER node for accuracy.
