    I just went out and shot my first load of reloads, with my results being ok. I used 168 SMK with varget powder, my goal is 1/4" groups at 100yrds. i got under 1/2" with my first trip out, just wondering if there is a different, maybe better powder i should be looking into? Im useing a rem. 700 sps tactical with 20" barrel if that helps.
    Thanx Goon

    Many swear by Varget & sub moa is quite good for a stock factory rifle. Sub 1/2MOA is going to take some experimenting. Bullets are #1, the SMK is the gold std but your rifle may like some other match bullet or a diff weight. Then don't forget to shoot your best load again @ 300 & see how it does. Some loads shoot really well @ 100 ten accuracy falls off past 300. Some shoot ok @ 100 & then better out @ 300, every rifle is diff. I could not get my best accuracy w/ Varget, but we are talking 1/8" diff in groups.

    Are you looking for accuracy to just 100 yards or further out . I have had some great loads worked up with the heavier Sierra match kings . I'm shooting '06 but I know guys loading them in .308 with outstanding results out to 500 yards. I can bust a grapefruit most of the times out to 400. Great bullet .

    Try going up and down with your powder in 1/10 grain intervals until you get it dialed in.

    shooting sub-caliber 5 shot groups off the bench at 100 yrds with Hornady 168 gr. BTHP match (#30501) and reloader 15 out of a Rem 700 SPS Varmint with a 26" barrel in a Choate Tactical stock.

    turning the necks and loading COL to be 0.005 to 0.010" off of rifling has given me the best accuracy.

    If you think you are going to get 1/4 moa out of a factory Remington you are either high or destined to be the worlds luckiest man. Remember there is a big difference between a 1/4 moa gun and shooting a 1/4 moa group. A true 1/4 moa gun is near ready for national benchrest competition shooting against multi thousand dollar custom built rifles and incredibly well experienced shooters.

    I've shot 1/4moa groups with a few of my guns but I do not own a 1/4moa gun.

    I shoot a .308 and so do many of my long-range shooting buddies.

    We all use Varget. We've all tried several other powders, but have never found one that performs better than Varget.

    If you really got groups that good on your first outing, don't change a thing. You'll probably not get better than that no matter how much you fuss around with it.

    As my shooting partner likes to say, if it works, leave it alone.

    my rifle isnt exactly stock, replaced the trigger with a timney group. also replaced the stock with a B&C a2 tactical stock, with full length alum. bedding block. for now i only have 100 yds to shoot may have 200 yrd range to try out soon. I made my first batch 42-46 grains. In .5 grain inervals. I plan on zeroing in with the varget to see how good it will get, just wondering if there are anyother powders that have a reputation for being accurate in a shorter barrel .308

    Varget or 4064.

    For 1/4 inch groups with a factory gun you are going to have to tighten the loose nut behind the scope.
  10. You may want to take a look at your barrel's "freebore" and try loading differnet OAL's (hold the same everything else) in increments out to the maximum OAL you can get. My Remington shot better the longer OAL I used.

    Then I ended up rebarreling and had the gunsmith ream the chamber of the new barrel for a specific bullet. Freebore is the distance the bullet travels before it hits the lands and grooves (rifling), and depends on the bullet you use as well as the reamer dimensions that made the chamber. Remington barrels are known for "excessive" freebore. No freebore at all is called "jammed to the lands". A bullet "jammed to the lands" rests right up against the lands after you chamber the round and close the bolt.

    Your groups weren't ok, they were outstanding. Everything from here on out is diminishing returns. That said, sort brass by headstamp and weight, bullets by weight, turn the case necks and in general, get super picky about everything.

    Thanks for the advice fellas. I will start with the tighting of the nut behind the gun, however i am pretty sure there is no helping that thing it just has problems. I will also try the oal asjustment. i have been fairly picky, i will increase this however. Im sure it will all help

    I've tried several different powder but always come back to Varget although Rl-15 runs a close second. Adjusting the OAL may help a bit but agree with .1 or .2 increments with the Varget may be your best bet.

    +1 That last .5 MOA is where things can get very expensive. At 100 yards I wouldn't bother. I've shot my 308 out to 500 yards and 1 MOA or better is plenty accurate out to that distance.
  16. Trigger job, free float the barrel, buy a more powerful scope. Adjust OAL and try different primers? Ultimately you are getting excellent results and I wouldn't change anything other than the trigger pull and scope possibly?

    Glass bed the action and free float the barrel.
    Have a smith square and true the bolt.
    Match trigger.
    Properly lap the scope rings and torque the screws.

    The next step is a new match barrel, hand lapped, air gaged and hand reamed to a tight match chamber and a short throat.

    After that you start shortening the barrel a few thousandths at a time to find the best harmonic.

    Asking better than sub 1/2 MOA from a stock Remington is like asking to drive a Porsche at the Indy 500.
