Something for reloading 165 to 175 grain bullets. Thanks!

Ooo, I know!

I am using 42.2 gr of IMR4064 or 39.5 gr of Vihtavuori N540 with the Sierra 175 gr BTHP loaded to 2.800" OAL. I think the N540 load is a little better but I need to get more powder for testing.

I use the same IMR load with the 168 and 180 gr BTHP bullets although I am pretty much out of the 180 gr business at the moment.

I shoot the 168 gr through a 1:12 twist Steyr SSG and the 175 gr through a Remington 700 with 1:11.2" twist.

They are fantastic loads! But YMMV...

And never trust loads from an old man with failing eyesight and marginal typing skills. Work them up yourself!

I like varget or RL15 both have performed well in my FN with 175gr matchkings

I am a huge fan of H335. It has been a very diverse powder for me. I use it in .308, .223, 30-30, and 45-70.

My loading for my 168gr HPBT .308win is 41.5gr H335 set at 2.810. The AR-10 eats them like candy. (Remember to always work up your own loads, using a reputable manual)

another vote for RL15, but I'm going try some Varget.

Varget, with it you can get higher velocity,lower chamber pressure and best of all, it's not temperature sensitive.

RL15 or IMR 4064.

TAC but only experience is with 147-150 grain projectiles.

Good luck.

Varget, unless you're shooting an M14 - then I'd chose H4895.

39.5 grains of TAC works great with 168 BTHP, WIN primers and LC cases. Excellent accuracy and very clean. AA2520 provides excellent accuracy as well, not quite as clean a burn. Varget works just fine, but seems to produce too much gas for my M1A.

I don't load .308 for myself but have helped my buddies do load development for their bolts guys. We've tried almost every powder mentioned so far. One those the best preforming by a nose was VIT however there is a reason why so many at the HIDE use and recommend Varget. For a gas gun I would look at CFE223 or Ramshot Exterminator.

I like RL15, but Varget and 4064 work well also.

Varget for a bolt gun.

I also use IMR 4064, but it does not meter nearly as well as Varget.

RL15 has worked well for me in my bolt gun and ar-10, i have used it with up to 185gr bullet weights with good results

How much Varget?

Sierra says 41.7 gr is MAX yet Hodgdon says 42.0 gr is START.

I would like to get around 2600 fps in a half-hearted attempt to match M118LR and that either takes 41.7 gr if Sierra is right or just a bit over 42.0 gr if Hodgdon is right.

The fact that Hodgdon goes up to 45.0 gr (compressed) gives me some comfort in loading 42.0 gr which is beyond what Sierra shows.

118lr is a 175 grain smk, right? I've never tried 175's in a .308...

My target load is a 168 grain a-max... I'm shooting 43.2 grains for a modest 2,600 fps from my 24" barrel. Darn accurate, and it will hold sub-moa for 500 yards easy. Closer to half moa inside 200 yards. Extreme spread hasn't ever come in higher than 20 fps, and SD always comes in around 8 or 9. :cool:

You can always start with the Sierra data (you'll often find an accuracy load on the lower end anyway). Keep in mind, Sierra tested with a 26" barrel Savage 12VSS. 2,600 might not be reality for your rifle depending on barrel length.

Try several diff powders, your rifle will haev a pref. There is no such thing as universally accurate rifle powders IME. I like RL15, VV150, 4895, Varget, they all do fine but diff rifles will like one just a bit better than the next. Right now in my M1, I am using AA2520. Supposedly a ball equiv to Varget & it runs nicely in any measure. TAC would be sim.

Right, the M118LR is based on the Sierra 175 gr BTHP Match.

I am shooting these through a Rem 700 with a 20" 5R barrel with 11.25" twist. I'm not too hung up on matching M118LR so I thought I would load some at 42.0 gr and see how they do.

The Sierra accuracy load is 39.5 gr of VV N540 and it is VERY accurate. Far less than 1/2 MOA at 100 yards. The velocity would be about 2400 fps with the Sierra test setup so I am probably somewhat less than that.

The 42.2 gr of IMR 4064 is also very accurate. I think I prefer the VV load but I need to do more testing.

I just happen to have a can of Varget and a couple of extra hours so I thought I would load a few at 40.0 gr (matching the Sierra 2400 fps accuracy load velocity) and a few at 42.0 gr to try to come close to what the M118LR might do although my barrel is 4" shorter.

Once I get a load that is super accurate (and I think I already have a couple), I'll run them over a chronograph and see what they are doing.

Try Varget. If that does not work, you might consider Varget.

If you are loading for accuracy, try Varget.

You think Varget might work with the Sierra 175 gr BTHP?

Seriously, I'll give it a bit of a try tomorrow. Care to share your load for bolt action? I'm probably just going to start at 40.0 and step by 0.5 up to 42.0 unless you have something more specific.

I have the cases prepped and primed.

43.0 - 43.7 using Lake City brass, CCI BR primers and pointed 175 Berger Target, non VLD bullets seated into the lands.

Same load using pointed Sierras, but Federal Primers and 0.010-0.015 jump.

I sometimes use Lapua brass, but mainly with Lapua 155s and Berger 230s.

With the Remington chamber and the Sierra 175 gr bullet, I can't get anywhere near the lands. I measured the chamber with the Hornady gauge and it seems like I need another 0.1" or more to even get close.

I am using Lapua brass for all of my bolt action rifle loading. In some ways that is a PITA because the Steyr chamber is larger than the Remington. I have to pay careful attention to which brass is which.

I'm not going to try to get beyond 600 yards with the 20" barrel and even that may be a ways down the road. For now I'm just going to shoot at 300 yards. I'm going to try loads at 42.0 gr and lower.

Thanks for the data!

For 200yd - 600yd loads don't overlook AA 2520. It meters like most ball powders (slick) and will give good accuracy out to 600yds. For 1000yds try 4064.
My Camp Perry loads for M14/M1A at 200-300yds, were 41.5gr 2520, LC brass, 168gr Sierra MK, Fed primer.
For 600 yds, same basic load with 42gr 2520, and 175gr Sierra MK.
Shot some very good scores with these loads over the years

Yep, AA2520 is qucikly becoming my go to powder for the 223 & 308 in semiautos. I see no reason it wouldnot preform well in a bolt gun. Many tout Varget, but when I had a M700VS in 308, it shot no better than 3 or 4 other powders w/ 168gr SMK.:dunno: It's why you have to test yourself, every rifle has it's pref.

I use Varget under 175 SMKs. Do work your load up, though... During my workup, I loaded test rounds up through max & a little bit above. I hit my rifle's max well under where everyone else was at with very clear pressure signs. I found a sweet spot during ladder testing & landed at 42.6 (chrono at 2650). Tight chamber? Dunno - but it's an awesome load.

Howdy GTR Folks,

1. It's been a long time since I stopped by, but I see info sharing is as good as ever!

2. So here's my Question for the .308 gas gun guys--- Using IMR 4895, has anyone used heavier bullets than the 147-150gr? I've got a bunch (1000s) of 175 gr bullets free from an estate of a buddy.

It will work fine, you are going to give up some velocity though to slightly slower powders like Varget or AA2520.

In no specific order (for .308/7.62x51mm) using Sierra MK 168s:

H-4895
W-748
RL-15

42 gr TAC, Federal 210m, Federal or Winchester brass, 168 gr SMK, shoots just as well as factory Federal GMM out of my Remington 700. Which means about 0.75 MOA all day any day.

They won't work at all and you should box them up and ship them to me and I'll send you 1 Hornady 150 grn FMJBT for each 5 of them you send me. :supergrin:

TAC - it used to be inexpensive- they (Ramshot Powder)now have a big head:upeyes: and jacked up their prices.
AA 2520- its o.k. but gets peaky in high temps outside if its hot.

use anybodys brass
use Speer 165 grn flat base softpoints. Excellent under or right at 1 inch group from a Savage Stevens 200 in .308. Even better in a Savage 110 (bought used at pawn shop) in .30-06.
