.308 Winchester

I thought I was in the same boat until I found the stash of IMR 4320 I had. I did a ladder test at 300yds and shot sub moa with it. I'm in the process of further refining it now. This was shot from a bone stock Rem700 Varmint in .308win. I posted the results in the ballistics and range report forum. As soon as I find that "ultimate load" I'll post here. IMR 4320 is worth a look for the 168gr anyway.

The thing I noticed about IMR 4064 is that it's now available in pretty steady quantities. Must be a factory of North American built versus "down under built".

Never used the 4320 but I'm sure it has it's possibilities. Too many powder types, too little supply of each :)

Haha true. I did a ladder test with the 4064 I had on hand too and it also shot sub MOA but the 4320 shot better to start. I'm still working on refining both of them to find out the clear cut winner so to speak.
 
Just shot this at my first 1000 yard match. The load did well (even if I didn't :p). If you run the numbers it has some huge drop but the least windage compared to other .308 loads.

Bullet: 210gr Berger VLD Target
Case: Lapua .308 WIN Match
Primer: CCI #200
Powder: IMR 4320
Charge: 40.8gr
COAL: 2.890"

Velocity out of my 24" Savage factory barrel is 2450fps. I don't have my exact ES or SD handy but the ES is under 20fps.

This is the trade-off when you go to a heavy bullet. They fly slower from a .308 but have more inertia to resist the wind "puffs". This is why some will use 30" barrels in competition. More speed to flatten out the trajectory and also get the benefit of the wind-cutting heavier bullet. If all you have to do is plunk down your rifle, shoot a few rounds ot to 1k, and then put it back in the truck, no big deal with the longer, heavier barrel. Haul one around all day, hunting whatever you "hunt", and longer barrels are no fun.
 
A couple of more good ones. These are 10 shot groups, shot from a 24" Brux barrel.

Been playing with it and found a good one. Here's 5 shots at 107 yards. Dot is a 3/4 " sticker that I buy at Walgreens

 
178 AMAX and 178 BTHP with 43.1 grains of Norma 203-B, LC11 brass, CCI 200 primers.

Here's one that is working great for me.

42.1 gr Varget
Winchester Brass
Wolf Primer
Nosler 175 Gr Custom Competition
2.825" OAL


10 rounds but in two groups. The top group was aimed at the center of the black center diamond. The next 5 were shot after a scope adjustment and used the top of the "pointer" where it joined the orange circle as an aim point.

ry%3D400


This load holds sub 1/4 MOA out to 300 yards (max range I had to test). One note, I get solid accuracy like this as long as I use at least .003" of neck tension. I just use a Forster Benchrest Full Length Sizing die now and don't bother with any bushings or neck sizing only. If I want to use the internal magazine on my rifle, 2.825" is max and that leaves me with a jump around .020". A Benchrest "Guru" I shoot with suggests that the extra neck tension replaces the "resistance" when fired as they get when the bullet is jammed in the lands. He always increases neck tension when "jumping". I might also add that he also wins a lot :).

Berger VLD Target Hybrid 200gr:

Just started loading up a few tester rounds and I'm looking for a little more information about this particular bullet. Berger replied to my email for specs becasue this bullet isn't in the manual yet. They said the max powder amount for Varget is 39.6 gr and I was wanting to hear from the Hide what powder amounts you guys are loading up.

The ones I've loaded up so far are:
Lapua brass (new)
CCI 200 primers
Varget 39.6gr
Berger VLD hybrid 200gr
Ogive 2.222

My stick is a Sako TRG-22 26" barrel.

Thanks guys, Happy Shooting
 
MR-2000 50.0gr
SBS brass
Wolf LRP
Nosler 155gr
Brux 1/11 twist, 30"

There was an OCW node at 48.5gr that run 2970fps. I haven't had a chance to chrono the new load at 50.0 gr. Per Dan's guestimate, the next node was very close to 3%. 600 yds, 4 into 3.5", fith shot opened it to 4.5" laterally. Held 2.5" vertical.

all of those factors/ componets have been well documented as a safe and accurate load........ I'd ditch the 168 and get the 175smk but that's me. additionally I increase the charge wt to 44.5 and cut an inch off that barrel.... oh wait that's my load for my gun...

20" remington 700 SPS tactical (stock everything) with a leupold mk4 3.5-10x40. Stock trigger too at 4 lbs.

42.0gr H4895

This is my new accuracy load.

Was using 41.6gr of h4895, and the groups (5rnd groups) were around 1moa to 1.5moa average.

The new load, at 42.0gr of h4895, I have fired only 10 rounds of. 5 rounds were chronoed (2580fps) and the next 5 I shot a group of 0.6 MOA at 100 yards.

Have yet to try varget, but have some under the bench. Don't worry about lot differences in hodgdon. The lot difference between varget powder is only +\- 8fps. So I'd say it's very consistent

Ok so I am new to long range shooting. I bought an entry remington 700 sps-v with 1-12 twist barrel. Plan on doing some work to it as a project to shoot 600 yards accurately. Stock, trigger, and quality optics are a must. I was wondering if the 168 Amax is going to be too light for 600? Should I jump to 178 or is my 1-12 trust too high? Going to use hornady brass, varget, and fed210. Thanks for replys.
 
Very nice group, Fuerte!

Jkling, I have the same rifle and have only shot factory ammo to this point. My 700 loves FGMM (168gr) very well. Sub MOA right out of the box with the factory stock. I have been following the FGMM thread in this section closely. If you can score some IMR4064 you may want to explore that option. I am getting setup to do some testing with my 700 with a hand - loaded FGMM copy to start some accuracy testing. I'll be using the load suggested and then varying a couple of grains high and low to shoot for groups.

From what I've read the 1:12 should shoot the 170+ range grainers should be just fine and out to 600 they will remain supersonic with a standard load. Getting out past 1000 is where the heavier bullet it's needed. All of this information is coming from reading threads on here so I think ultimately testing will need to be done to see how your rifle reacts.

thanks for the reply. I plan on picking up a lot of different bullets to test but just interested in what you guys think I should start with. Thanks again

You don't need to waste money trying lots of bullets, 175 Sierra Match King or 178 AMAX will be fine for a long ways out. After you get more proficient you might want to change down the line but most are happy with one of these and they won't break the bank.

I still shoot the 175 SMK's after many years.

I agree those are awesome bullets and I don't "need" to get others but I like trying different bullets especially for hunting. The Amax is alright but I don't want to use match bullets for hunting. I love the Barnes ttsx for anything deer size and up.

Then state all your needs to get an accurate answer, long range accurate shooting to 600 yards is not usually associated with hunting.

good luck on your new endeavor,

New load discovered yesterday.

Winchester Case
Nosler 175 gr Custom Competition
Fed GMM 210M Primer
47.3 gr CFE223 (.2gr less than max)
2.810" OAL

Rifle, 24" 5-C Benchmark Barrel on Rem 700 SS
B&C Medalist Varmint/Tactical Stock
Sinclair Tactical Bipod
Timney Trigger
NF 12-42X56 NXS


Group size .33 MOA @200 yards. .2 gr less or .2 gr more started the "scatter group" so the 47.3 gr charge weight is dead on for my rifle.

Nice to have a powder that I can use in both my .223's and .308's. Also helps that I have two jugs of the stuff :)
 
175gr SMK at 2580 FPS will be 1175 fps at 1000 yards at sea level, around 70 degrees. Subsonic is around 1150 fps, so don't worry about that.

45gr R15 behind 155gr Bullets seems to be a good accuracy node in my rifle. Two different bullets, two different cases, two different primers but the same powder charge produce great accuracy for me. These are 10 shot groups.

Federal GMM twice fired brass trimmed back to 2.005
IMR4064 at 42gr

I was able to achieve a .58 group at 100 yards. This was my first time trying this load and also this was the first time shooting this rifle. I have more to work with on it but Im happy with the load so far.

I fired a total of 6 shots. The lower one to measure the round size and then the 5 shot group in the center.

Anybody interested in this combination should see the link below, where Dan Newberry duplicates the FGMM 175 round using these components. Very good read as he adjusts for variance in weight between manufacturers brass. The above load is almost right on.
