42.0 of IMR 4064 pushing a 175 Match King is an "Index Load" -- if your rifle doesn't shoot it well there's something's wrong with your hardware.

44 grains of Varget will push most bullets accurately in a bolt rifle.  Stick around 42 to 43 for autoloaders.

Dan Newburys ocw recipes:

.308 Winchester using IMR 4895
150 grain bullet, 46.6 grains (extrapolated from following loads, untested at this writing)
155 grain bullet, 45.6 grains
168 grain bullet, 43.6 grains
175 grain bullet, 42.4 grains
178 grain bullet, 42.0 grains
178 grain bullet, good match load... use 41.7 grains with Lapua brass, 41.5 with FC brass.

.308 Winchester using IMR 4064
168 grain bullet, 42.8 grains
175 grain bullet, 41.8 grains
(these replicate Federal Gold Medal, use FC or Lake City brass)
We like 178 grain bullet and 41.5 grains in FC or LC brass

.308 Winchester using Varget
155 grain bullet, 47.8 grains
168 grain bullet, 46.0 grains
175 grain bullet, 45.0 grains (an all around favorite)
180 grain bullet, 44.1 grains
200 grain bullet, low node 41.5 grains (10 twist barrel)
200 grain bullet, high node, 43.1 grains (10 twist barrel)

CCI 200's, BR-2's, and Federal 210's work well with Varget

Any idea what kind of velocity you're getting with this load?  I have a bunch of hornady 168 hpbt and 8lbs of 4064 on the way. Looking to get close to my imr4895 loads at 2690 avg. with good accuracy.

Worked up loads for 208 gr Hornady ELD-M using varget. Weight is next to the target. Even though the 41.0 gr shot best, had case swipes so will go with 39.6 gr and adjust OAL to see if I can tighten them up. The bottom center was my 178 ELD-X to foul the barrel. Shot from my Savage 10T 308, 1:10 twist, 5R, 24 inch barrel. Brass was Lapua and CCI primers.

My Savage with a McGowen barrel likes

175gr Nosler Custom Comp
43gr IMR 4064
Federal 210 primers
Seated .006 off the lands

I shot the MOA Challenge with this round. It shot .808MOA average for 5 5-shot groups off of the bipod here.

It also likes the same powder charge, primers, and having the bullets set .006 off the lands with 178gr A-max and 180gr Nosler Partitions.  The A-max group about the same as the 175 custom comps. The 180gr paritions shoot just under 1 inch at 100yd.

Case: Federal Eagle reloads.  Full length sized.



Bullet:  178 Grain Hornady AMAX ( polymer tip boat tail )



Powder:  IMR 4064 @ 40 grains even.  NOTE: ACCORDING TO HORNADY MANUAL (9th Edition)for Service Rifle (specifically M1A), this is a HOT load and is one grain OVER the MAX Service Rifle Data. However:  Under Sporting Rifle this is under MAX load of 41.3 grains.  Since I am using a Mega MATEN with an adjustable gas block, I decided to set the gun to this load by creeping up on it from 37.3 grains initially.



Primer: Winchester Standard Large

C.O.A.L.:  2.805"
Barrel:  Jp Precision, .308, medium contour barrel w/ matching bolt.  22 inch barrel with 1/10 twist, Syrac Ordnance adjustable gas block on Mega MATEN reciever. Surefire SFMB 7.62 Brake.



Optic: Leupold Mk IV 6.5 X 20 on a zero cant ADM mount.
Once I started getting good with this rifle and with interfacing it with a rifle rest ( Caldwell lead sled DFT ) 1 inch groups aren't too hard to achieve at all. I am REALLLLLY new at precision auto loaders so I have a long learning curve ahead of me.
I am throwing charges individually on my Dillon RL 550 with an RCBS manual throw powder measure adapter on a Dillon Powder die.  I check my loads about every 15 to twenty rounds.  These AREN'T hyper precision loads by any means with a lot of size die variance you might not get with a single stage system.  
 As I have said this is a hot load that I crept up to.  I am stopping here until I have more data.  So far, my primers are lightly flattened but not cratered or pierced at all.  Firing pin hole is smooth and clean so right now, everything seems to be pretty typical for AR-10 brass.  Ejection is moderate, not violent.  Brass is still measuring under trim length of 2.015.  Most are at 2.010 or better.  Case Trim To is 2.005 prior to loading.  I will NOT load these more than three times.
Published data indicates I should be around 2350 fps.  I am working on getting a MagnetSpeed chrono in the near future so I can publish the data.
 Again, if I went to a full single stage system and started trickling charges and REALLY got picky with case dimensions, I could shrink these.
 Here is a very common sample of how it is shooting now at 100 yards:


Variance, in my opinion is due to manufacturing variance in my loads and variance in my interface with my gear.  I am very darn happy with this setup so far.

I planned to use the same (or close) charge weight for both the 168 SMK and the 165 SGK. What I plan to do is change the COAL. I think I may have better consistency between the two if I use my comparator and measure from the Cartridge Base to Ogive and make the two loads identical in thier jump. It seems to me that it would make more sense than simply using OAL, since in reality the tip makes little difference compared to the Ogive.
I read a lot on precision loading but this rarely comes up, as most have one "go to load" and stick with it. My purpose is to have one rifle to use for hunting and precision rifle, without having to drastically change between hunting and target loads. Adjusting for CBTO from one type to the next is simple enough with the Redding Competition Seater Die, and takes moments. The trick is repeatability, which can be achieved by using the same tooling, tools, and rifle. My CBTO measurement would be useless to anyone not using my equipment.
If this works, however, I will post the COAL for each. Just in case there are others who want a simple transition from Hunting ammo to Match ammo. Since you have used the same load data for both the SMK & SGK, please tell me your experience, and perhaps your charge weight and powder, if you don't mind. I know this thread is a couple of months old, and I don't yet know if Admin sends emails if someone replies to your post...
I'll keep a lookout.

For those that have loaded the Sierra Tipped MatchKing Rifle Bullets .30 cal / 7.62mm .308" 175 gr. TMK Match how do they compare to the tried and true SMK's in the same weight.

Great info here.

It would be great if we could get a condensed version of the loads in a break down of whether the loads are for bolt or gas guns(I have noticed that the gun type is missing from some of the load data).

It appears that the general consensus for gas guns is:
175-178ish grn bullets
-4064 - 42+/- 1 grn
-Varget - 42-43 with one claim of 45 out of a M1A

168 gr bullets
-4064  -  42-43
-Varget  - 43-44

Rifle = Rem 700 1-12 twist rate / 26 in barrel.
Hornady 178 Amax
IMR 4064
Once fired Hornady case
Remington large rifle primers
2.005 / 2.800

I don't have a chrono so I am starting low on my powder charge, and I am shooting for groupings as to velocity ( for now )...I am using the Hornady 9th edition book.





It looks like I will be testing 41.5 to 42.0 on my next range time, and this time I will be shooting 5 rounds per string ( Layman 49th says 44.3 gr is max )

I have re-shot 40.8 and this is what I got....left target is dirty barrel.





EDIT:

The 40.8 was chrono'd using my new Magnetospeed and it was moving at 2480's average with 5 rounds that I fired. I tested the same load on my M24R and it was shooting half inch hole at 100 yards...

Same question here. Any differences in COAL or Varget loads for 308 175gr TMK vs SMK.?  Any info about same questions for 168 gr TMK Vs SMK  would also be appreciated.

For quite a while I used 43 gr Varget behind a Nosler or Hornady 168 gr HPBT Match bullet.  This was in LC or FC brass with CCI 200 primers at 2.80 OAL.  Very accurate in my Rem 700 SPS 20".

When Varget became hard to find I tried IMR 4064 with the same setup.  The FGGM clone load of 42.8 gr  will shoot sub MOA in my Rem 700 and my 18" Aero Precision M5 .308.

As a point of interest. I chrono'd factory FGGM and the IMR 4064 load at the same session through my Aero .308.    Results were 2561 fps for the FGGM and 2562 fps for the 42.8 gr 4064 load.

Was at a 1000 yard range a couple weeks ago trying my 338 Lapua my Lapua Magnum. No problem with this beast. Decided to bring the 308 along to see how my pet load for my 308 could do. Hit 4 out of 10 shots banging steel. Was a rolling type of range so know the wind was hard to determine. Am still impressed with this load. A bit hot but seeing my misses right next to the target tells me this rifle is plenty capable at 1000 yards. The 338, after 3 shots to get on target, hit steel every shot.

My pet load for my Savage 10FCP-SR is FC brass with 43.7gr varget and 210 primers. I usually seat them to OAL of 2.800 and it shoots around .75" at 100.

I retried an OCW test at 20 thou off the lands and only 2 charges were under MOA.
Have you played with the seating depth at all?

43.5 Varget
Hornady brass
CCI 200 primer
168 Sierra TMK
2.222 base to ogive

Edit
26 inch 700 varmint with 12" twist
2653 average 5 shots
SD - 4
ES - 10
.75 inch with chrony bayonet not attached on another 5 shot group of smae load. They bayonet opens up my groups ON THIS RIFLE.

My 308 is very finicky, compared to my 6.5 creedmoor. This load and length is the only combo that I have found, that shoots as well as my go-to 168 GMMK. I have some SMK 168 and 175 bullets on the way.

It is fairly dirty. I don't know how long precision would last.

Try a magnum primer those loads shouldn't be dirty. And the extreme spread is a little high. Or a match primer. I used to love the Hornady 190 bthp match bullet. In front of imr 4064 or BLC-2.

ESBVader - check your IM's.

You're too hot, over 1.0 grain higher than Sierra's maximum and approximately 150 fps faster than "safe" for your barrel length.
