carl 0 Posted December 16, 2009 Report Share Posted December 16, 2009 I have a S308 with 16inch barrel, DPH beryl style mount, with a Nikon Prostaff 40mm scope mounted up. Shooting at 80yds I am having trouble getting any decent group. I have tried surp FMJ ammo and 150 win. power points both with same results. The only thing I can think of possibly helping or being the problem is the tension screw on beryl mount. Any suggestions???? the gun is new with clean barrel approx 80rds through her.

KrisFox 69 Posted December 16, 2009 Report Share Posted December 16, 2009 Does your scope feel tight? If so try bullets heavier than 150 grains. Quote Link to post Share on other sites
carl 0 Posted December 16, 2009 Author Report Share Posted December 16, 2009 yea, rings are tight. do they throw better groups with heavier bullets? Quote Link to post Share on other sites
RobRez 1,895 Posted December 16, 2009 Report Share Posted December 16, 2009 Mine does fine with 150 gr at 100 yards open sights I usually shoot a 2" to a 3" group using a rest. Seems to do the 3" to 4" with surplus ammo. If your scope is set up good, is your trigger stiff enough to account for some of the bad groups? My trigger is super smooth and it makes at least 1" diff. to me. How bad are the groups? Quote Link to post Share on other sites
mav 459 Posted December 16, 2009 Report Share Posted December 16, 2009 Is you beryl polymer? Quote Link to post Share on other sites
carl 0 Posted December 16, 2009 Author Report Share Posted December 16, 2009 the beryl mount is alumn. the group was very inconsistent, around 3 to 4 inches. Quote Link to post Share on other sites
carl 0 Posted December 16, 2009 Author Report Share Posted December 16, 2009 the factory trigger does seem very stiff and to have a long pull. Is there a aftermarket dropin available for a decent price? I forgot to say I was shooting from lead slead so I dont think that stiff trigger would have affected it to much.

RobRez 1,895 Posted December 16, 2009 Report Share Posted December 16, 2009 Well, I'm thinking that a standard AK with open sights would be expected to reliably shoot a 5" group at 100 yards, some say that number could be as low as 2" to 3" but with a 16" barrel maybe a 3" to 4" group is not as far off as it seems.I'm not sure if the scope will do too much to help. It helps me to have a partner at the range to observe how I shoot and help me go through the checklist of making a good shot. If you are not so familiar with this weapon you may be doing something that you don't realize. Quote Link to post Share on other sites
carl 0 Posted December 18, 2009 Author Report Share Posted December 18, 2009 so does anyone have experience with the DPH beryl style mount? Quote Link to post Share on other sites

BigBump 1 Posted December 18, 2009 Report Share Posted December 18, 2009 you also might want to try having your barrel recrowned. Quote Link to post Share on other sites
G O B 3,516 Posted December 18, 2009 Report Share Posted December 18, 2009 With cheap ammo, 3-4" groups are average. More practice and better ammo = better groups. Quote Link to post Share on other sites
cscharlie 107 Posted December 26, 2009 Report Share Posted December 26, 2009 I would inspect spent brass for clues. Inspect round after being chambered for deforemation. If I could, I'd inspect the inside of the barrel, including the chamber for defects. Would also check head space. Then ring allignment make sure the scope is not tweeked.

psignore00 0 Posted December 27, 2009 Report Share Posted December 27, 2009 You know if you still have the owner's manual it has your rifle's 4 shot group at 100 meters on the "acceptance certificate" page (mine is page 19). It's handwritten in and mine is 97mm which is 3.8 inches. I thought it'd do better than that, especially during factory testing, but who knows what kind of junk ammo they were using.

XXasdf 29 Posted December 27, 2009 Report Share Posted December 27, 2009 Just as the others have said, your shot groups are pretty consistent with a standard 16" saiga .308. 3-4" is what I usually get out of my Saiga with 150gr Austrailian surplus rounds(@100yards). Although I did get slightly better groups with 168 PPU match grades. My suggestion would be to try out several brands of ammo until you find one that suits you, for me 3-4" is good enough. Recently I've purchased some Brownbear 145gr rounds so I'll see what kind of groups I get with them soon as I make it up to the range. Try converting I'm sure the stiff and creepy stock trigger reduces ones ability to get a more consistent group. Quote Link to post Share on other sites
kresk 10,063 Posted December 27, 2009 Report Share Posted December 27, 2009 Agree with some of the other comments--find what kind of ammo it likes best and the accuracy may improve some, but the groups you are getting are not unusual for an out-of-the-box S308.

carl 0 Posted December 30, 2009 Author Report Share Posted December 30, 2009 thanks for suggestions, I have been stocking up on ammo to test and hopefully get better results. it is going to be used for hunting deer in woods with shot at 100yds and under but I would like to squezeze as much accuracy as possible.

RobRez 1,895 Posted December 31, 2009 Report Share Posted December 31, 2009 I went hunting with mine this year and felt totally comfortable with ranges to 150 yds with the open sight. Didn't shoot anything...but boy was I ready! I hunt in the thick mountains of Montana and feel it is a fine choice of weapon for deer and elk in that terrain. I must say that my super smooth trigger made a difference in not anticipating the shot, for me and really helped keep my standing offhand groups to about 5" at 100 yards with no scope. I feel that it equals a kill shot with the type of shots I take at game. Granted it is not the same as a sure heart shot and drop with my .270 bolt rifle or my .308 bolt rifle, but dead is dead, time to eat that Sum'bitch! Quote Link to post Share on other sites
