I was working up some 155gr Hornady ELD-M loads yesterday, using IMR 4320, FGGM primers and virgin Lapua brass. All rounds were shot through 20" factory Remington 700 barrel and a MackBros MB762L can.

Anyone have a load for a Savage MSR 10 Long Range .308? I just got one and was curious if someone had found the sweet spot on theirs yet before I started building my loads.

Try 43 grains of Varget under a 175SMK and work your way up in .2gr increments until you find the sweet spot. Thats been a tried and trued method for me in every .308 I've ever played with. You likely won't get past 43.7gr before you find the one that works best.

Alright been googling to no avail. My brother is having a custom 308 built. I'd prefer he go short 6.5 personally but i he wants more energy on target i get it, and i think it's still very viable assuming i can reach the speed i want to. Problem is he wants as short as he can go. So i'm trying to think of ways to get a 155gr TMK to 2800fps or maybe a 168gr TMK/ELD to 2700. I know 2000mr is an obvious go to but i'm not sure on it's temp stability. I have some 8208 and thought about trying RL16.

Thoughts?

Superformance, CFE 223, or 2000mr would be my guess. I wouldn't bother with the RL16 unless it was 200+ gr bullets and a longer barrel was being run.

Ive ran 2000mr in my 20.5" 308 and had 175gr smk running 2770fps so it may be possible but to be realistic, i'd expect lower velocities with a 16" barrel.

While it may be more costly, these Lehigh's may be more help achieve what you're brothers trying to get done.

It's not chambered yet i might can talk him into 18" which would give me more headroom finding a load. I saw CFE had some serious velocities from Hodgon's chart. Is it temp stable? I have some 2000MR but i see varying reports of it's stability. 2700-2750 with a 155 might end up being more of the target than a 168 at 2700.

I haven't used CFE223 but its probably the same or possibly slightly better than 2000mr. Barnes is showing CFE 223 as their most accurate powder tested for the 155gr Match Burner @ 2960fps in a 24" barrel. They're also showing Varget @ 2920fps.

Just talked to him looking at my 18" 6.5x47 he wants 18-20 now. I don't think he liked how stubby it was going to look at 16". He's thinking 19" now. Should be able to hit my mark on either bullet at that point albeit pushing. I had 2630fps out of my 20" 5R with 178s over varget.

I'd do a 20-22". 2700+ with 2000mr and 185r hybrids or you could try Rl16 with 208 Eld-m's or the Berger 200.20X. I'm getting 2648 out of my 20.5" Hawk Hill with target and 178 Hornady's and will be switching back to the 185 Bergers and 2000mr.

Idk that he’ll go over 20. Can’t blame him with the can. But I’ll run it by him. I see your point though the high BC 30s are in the heavies.

Ive tried the 208 Eld's with Rl17 in my 20.5" and stopped somewhere between 2450-2500fps from what I recall. I'm sure I could have gone higher but was mag feeding and didn't want to trash new peterson brass.

I'm going to order some Win brass and try the 208's with Rl16. I think when I ran the numbers I need around 2550 fps or more to match the 185gr hybrids @2700.

That would leave me to assume that with the 18.5" barrel, 2600+ fps might be achievable with 2000mr and 175-185gr bullets, same with CFE 223. I'd be curious if small primer brass would benefit much also.

I've been extremely interested in that since moving to 6.5x47 and seeing 6.5CM transition to the small rifle primer. I push the ever living hell out of my 6.5x47 and am on 12 firings and still going. This is second hand brass also. But i've already got a ton of nosler and lapua 308 brass for him to use. I don't own a 308 anymore. Had planned on a 16" Aero M5 but never got around to building it after Trump won. So he pretty much has everything at his disposal to load with. If he goes 19" like he's thinking i'm almost certain i can get 2600 with 175/178s. I've become more a component for lighter decent BC with higher velocity versus slower heavy pills with less velocity as of late. At least for my application that works. I'm basically just looking at what best the wind most. A 168gr TMK at 2700 is equal in wind calls to my 123gr ELD-M at 2840fps from my 18" 6.5x47.

Honestly i'd like to AI his gun with a 308 fireforming is insignificant on barrel life. Would drastically reduce trimming. Though if he ever shot a PRS match it'd be problematic. I'd lose my shit losing fire formed brass.

Hey guys... new to the forum and relatively new to reloading. I was hoping I could get some input. For work I carry Hornady 308 168 grn. A-max. I will continue to carry that at work (not my choice), however I am looking for a load recipe that will get me close to the A-max. As of right now I was just planning on using the 168 a-max but unsure about powder, powered amount and primer. I would like something that has similar data so I can switch from weekend fun to my work round without too much change. I am running a 20inch Rpr. Thanks for the help.

I don't know what the velocity of your bullet is and sometimes just matching it doesn't make it accurate. I can only tell you what works for me in my gun. This is a one hole @ 100yds load in my 20" 1:12 twist barrel:

Nosler Competition 168 BTHP
43.5 grains Varget
Lapua Brass
Federal 210 Primer
OAL 2.80

Anybody have any pet loads for a 16" AAC SD Remington? I have some 178ELDXs coming.
I don't but I am just getting set up to do load development for my new 16.5 SPS Tactical. I plan to ladder test to find what works best for my barrel and the 175 SMKs I have but also want to try the Berger 185 juggernaut and maybe the 160 Flatline as well but they are $$$. You might find this article helpful https://rifleshooter.com/2017/01/short-barrel-16-5-inch-winchester-load-development/

Cheers!
