R17 .308 data

[rjacobs]

I have been searching here and several other websites and am coming up with lots of differing info on recipes for R17 and the .308. And the Alliant website doesnt help AT ALL.

I am planning on loading to 2.800, maybe as long as 2.850 since eventually I will be running an AICS mag system in a Rock Solid chassis. Rifle is a Rem 700 AAC-SD.

Looking for R17 data(min and max) for:
208g AMAX
185g Berger Juggernaut & Match BT-LRT(same bullets, different name, from the research I have done)
178g AMAX
175g SMK

I dont have a chrono(yet) so I will be running these up to check for pressure signs(3 rounds a piece, .5g increments) and then running OCW testing to find my most accurate charge weight(5 rounds a piece, probably .2g increments).

Thanks for the info.

You are gong to have to work it out for yourself. FWIW I have loaded up to 50 gr with 208 AMAX but that is hot and depends on local temp. Worked ok for me at 5 deg C but when I got up to 20 deg C with a hot chamber it was getting a bit stiff.

I know I am going to have to work the loads myself, thats obvious, was just hoping to find a min load to start with at least and where people had found max loads so I dont go loading to like 55g and just waste components.

Just was hoping to find some min/max loads so I can at least start there and have an ending point. Being to low is just as dangerous as being to high IMO. Also dont want to load like 100 bullets of each just for pressure testing.

I have run 49.2 grains in Winchester brass under the 178 AMAX @ 2.810 with great results. 2670 out of a 20" Krieger.

Right now I am close on a load for a 16" semi-auto. It's looking like 48 grains under a 178 BTHP @ 2.800. Should be around 2480 FPS.

awesome. What did you start on the bottom end? 45g?

My records for my aac-sd:
44gr RL17 netted 2310fps under 175smk loaded to 2.86" OAL in RP brass using Winchester Large Rifle primers
49gr RL17 netted 2698fps under 175smk " "
^also saw same results using Winchester brass, no pressure signs at 49gr but I was just starting to compress powder

awesome, thanks. I got 600 175g SMK's to play with.

Now if I can just get the recipe for the Bergers. I THINK I am going to start with 43g and work up to 47 as I saw a load with a 185g Lapua where they maxed out at 47(I think, I will have to look again).

Got the numbers from Berger. Took them a while to email me back and send me the data they have for the 185's.

I used Quickload to give a starting point, then did an OCW test around that charge. I don't think I have tried anything less than 47 grains in Winchester brass. I have chronoed many of these, and it's not worth it to use RL17 at less than 47 grains. Might as well stick to Varget or RL15 if you have to go that low with the 17.

What were the # from berger i am going to try the 185 in my gun im having built. 26" 5r 10 twist.

Montana Marine has done extensive testing with the .308 and Re 17. Look for post #31 under Range report and exterior bal.
