If your looking at that route I'd personally take a really long look at the Berger 185 juggernaut. The 208 AMAX is a good choice as well FWIW if your rig is a 1-10 twist , though may end up as a single feed as those 200g and up .308's are pretty darn long and get into the powder space if you load to magazine length. I'd look for best accuracy consistently then and only then velocity. R-17 is a viable choice for either bullet IMHO in your 308. YMMV

RL 17 will work with the 185s but Power Pro 2000MR is better with that bullet weight if you don't wanna go the Varget route. 2000MR gives me 100 to 150 ftps more velocity than Varget with the 185s. Once you get over 200gr then RL 17 is the route I would take. A friend of mine that I shoot FTR matches with does really well with RL 17 and 208 Amaxes. 2000MR is like rocket fuel for a 185gr bullet in 308, especially if the barrel is fairly long. Its extremely accurate in my gun also.

Re: Powder advice needed

H4350 is very good in my 6.5 creedmoor with every bullet I have tried between 120 and 140 gr. I have been wanting to try RL17 as well but the H4350 has been too good

Re: Powder advice needed

Would the power pro work in the Creedmore as good as does in the .308 Spec. Does any know were to safely start with the RL17 in the Creedmore.

Re: Powder advice needed

Yeah start with 35.5grns of RE17 under 140s 38grns under 120s. I use RE17 in 6br and 260 with light bullets, and I've noticed what a lot of others have as well, if you aren't using 17 in a round that you can use a compressed load you get great velocity but often the ES and SD numbers are horrible, with compressed loads ES stays in the low teens, 17 is better for some of the low capacity cartridges that can benefit from an H4350 burn rate but do not have the space for the 4350s, 17 gives a denser charge. As for shot to shot consistency you're going to be hard pressed to beat the consistency of H or Imr 4350 even though your velocity will be lower. But if your chasing speed VV N550 would be another good one the try as well as Ramshot Hunter.

Re: Powder advice needed

These are the first three shots toady with Factory Hornady 140 Gr Ammo (H4350) through a cold clean barrel, this includes the fouler.




This is three shots of a 120 gr NBT over H4350 with CCI200 primer. I had 4 loads made up to test the NBT's and this was the best of the 4 but the others were not terrible.

I don't have a Creedmore but i would tend to believe it would work very well in that caliber. 2000MR was designed for heavy bullets in 308 and 223 but it works well in multiple calibers. Only one way to find out.

H4350 is a great, proven powder and works extremely well in the Creedmore, 260, and 6.5 X 47 for accuracy and velocity. VERY temp stable also.
