tried some new loads for my .308 rem700, had been shooting 150gr matchkings with oal of 2.8 in with great results, tried a oal of 2.84 and not so good, tried 168gr match kings and great results at 2.8 oal, but not so good at 2.84. the 168gr also shot a inch low. going to try differant powder charges next with the 168gr matchkings. the differance between results were 1 3/8 in for 10 rds at 100yds, out to 1 3/4 in for 10rds at 100yds.
 
odds of him seating 168s into the rifling on a 700 with factory barrel are slim
 
Try IMR4064 (yes, I know it's a pain) and RL-15 (use soft primers). Personally, I really like near-max loads with 168s, H-414, & magnum primers (or at least a hot primer like Winchester)

BTW, if you are using a hot primer with your present load, try using a softer (milder) primer like Rem or Federal. Sometimes that will close up groups.

Geeze, you groups are not that bad for 10 shots, anyway. Statistically, that is a good number.
 
using rem and win brass and win primers, btw only using a harris bipod for a rest, the rem 700 has the heavy 26 in varmit barrel.

I know each rifle will have it's own peculiarities, but they can be seated into at least the leade.

When I was working up the load for my 700, I started with the ogive just touching the lands. Used a sooted bullet to find the seat depth for this. As it worked out, the accuracy came in at .030" off the lands.
 
I'm fairly new to High Power Rifles and long range shooting. As I worked many loads trying to find the '' MAGIC LOAD ''for my barrel, I found that you have to be VERY careful to make sure that the shooter isn't the reason for a lack of accuracy.
Make sure that EVERY SHOT has the rifle on the bags, or a rest and a bag perfectly the same! Shoulder pressure and the way your cheek rests on the stock are important too.
You're got to have perfect consistancy in your shooting to find out how good your rifle really shoots.
Good luck!

kennedy,

Your loads are EXTREMELY light for that brass, especially the Winchester brass. When I was loading for a friend, we used 43.6gr of IMR4895 in Remington brass with 175gr Sierra MatchKings for 2650fps out of his Remington 26" M700 Varmint Rifle. I realize that there is a difference between IMR4895 and H4895, but not that much.

your rifle must have been manufactured before the lawyers took over. the problem isn't so much variations in individual rifles as it is lawyers who think the the lands should start halfway down the barrel so no one can sue them when some idiot reads a couple of internet posts and decides his starting load should be 10% over max ("cause powder mfgs are too conservative") and seated into the lands (cause every internet/armchair-benchrest shooter knows you should seat at the lands)

none of the 700s I've measured in the past 5 years or so could seat a 168g at the lands. in fact, none have even been close. iirc, they've all been about half a caliber short
 
UUSR,

If that is the case, how glad I am. (obtained new in Feb. '03) 1358 rounds down barrell now.

I try to compete in local informal benchrest club matches (factory class) and do very well (in my opinion) as long as I am doing my part. The load I've devised will group between .3 to .6 at 100 and a tad over an inch at 200. Last match I shot in (over a year ago) scored a 246-10X at 100 on a varmint for score. Again, it all depends on my doing my part...consitently.
 
i'm not familiar with the scoring there. is that out of 30 shots? is the x-ring 1"?

i measured a pss this past autumn for a local policeman who handloads in his free time and it would not touch the lands.

the great thing about the 700s though, is that almost all of them shoot well without the bullet being anywhere close to the lands. that's the real point. don't seat it into the lands if you don't have to.
 
Taliv,
Thats 25 rounds. 5 sets of 5 targets, 1 round per target. A perfect score would be a 250-25X. the 10 ring is 1/2" and the X is a small X in the center. That match is shot by the club on an IBS hunter class target.

i dunno... could be, i guess... but i have a couple remington 700 308's that reach just fine. at any rate, lands or not, i still suggest he try varget/rl-15 and see what happens.
 
kennedy,
H4895 is a good powder for the .308 but it you are getting spotty accuracy you might want to try a different powder like you said. Varget is a very consistent powder and tends to make very accurate rounds. A charge of 44gr under both 150gr and 168gr MatchKing bullet is a good load from what I've seen.

If you would rather use a Spherical powder rather than a Extruded powder give BL-C(2) a try. It too is very consistent and accuracy. I'm sure you will like either for loading your .308 rounds but BL-C(2) is building a very good reputation for accuracy.
 
dakotasin, how old are your 700s?


owens, that's pretty good! seems like that 25th round would be kind of hard to score though after you've already put 24 30cal holes in an inch
 
I've had good luck with RL15 and Varget. My "akrit" load is 42.0gr RL15 behind a 168 SMK or 168 Nosler Comp with seating out to 2.875 OAL.
Using Rem700SS 5R, standard factory sucky chamber. I find to touch the rifling I would need to go out to 2.965 OAL......way too far out for 168gr bullets I think.
From what I've seen so far, it hasn't affected my groups by much, even seating to standard 2.800.
Still working on my end of the accuracy equation though. I think I have been the limiting factor. A hand-full of sub 1/2 MOA groups and best so far being .275, 5 shots at 100yds. Last weekend I managed 4 shots bug hole at 200yds and screwed the pooch with the last shot out to 1". :-( Would have been the best group of my life.
My conclusion, chasing groups is kinda like gambling.....it gets addictive. The next one could be a new personal record!
 
taliv- the bdl was bought by me new from a gunshop for $425, which would make that probably a 1997-ish manufacture. the vls was bought new in 2005, the lvsf was new when i got it - maybe 2006. the adl is pretty old - maybe late 70's early 80's manufacture.

the vls seats noticeably longer than the others, the lvsf and adl seat about the same as my pre-64 winchester, which is about the same as an old savage 110 in 308... the bdl is in between.

all of 'em run well on varget. rl-15 gets better velocity in all except the vls (and accuracy is roughly the same as varget). the 26" pipe on the vls gets better velocity w/ varget than rl-15. varget does not get the velocity out of the shorter barrels that rl-15 does, though.
 
dakotasin, that's pretty much my experience (newer == noticeably longer, older == just fine)

totally concur on the r15. it's what i've used forever.
 
I just made up some loads with 165's, 168's and 150's starting with 42 gr of Varget. I got touching holes with the 150's [2.765] and 168's. [2.81] 43.5 /165 SBT had bullseyes. I'll have to try 44 for some 168's, and see how they do out of my Stevens .308
