To Waitangi.

Have seen and heard of three 708's now that don't like 140gn bullets. Everyone was shooting 120 rem factory loads really well but spat federal 140's about the same as you're getting. Admittedly they were bolt actions but were different brands of rifle. I would suggest trying them and seeing if that helps

Good for you. The scope in my Ruger scout couldn't hold zero. Swapped to cheap steel rings and no problems. Alloy one piece like talleys are good but not rings only. Had steel bases and alloy rings on my howa, same problem. Epoxied Talley one pieces on and no problem.
Experience says alloy rings are no good for a 308.

Yeah YOUR experience which is subjective not proven as you have put it. However everyone will have varying views, steel is better but the alloys can be fine as well.

You are using a sample size of two to base your statement on. Ridiculous!

I suppose that means the Nightforce Ultalights are not up to the recoil of a .308 either?

What your fuckin problem?

cheap and nasty is cheap and nasty, regardless of material!

Once you have done this and the info bully and some others gave
take a look at the crown, doesn't take much of a burr to muck with grouping
25--30$ will generally fix a crown issue.

yes.

Firstly check all screws are firm,action to stock,bases to action, rings to bases, rings to scope as applicable.

If this is a brand new rifle I would not be happy with a best case senario of 2 inch groups at 100y and you are right to ask the question.

Secondly get somebody else who you know to have an accurate rifle in a similar caliber to shoot it, if it suddenly shoots inch groups or better you have found your problem.

Thirdly if it is still shit try(beg borrow ) another scope that is known to work well and try again.

If no change id be hitting up your retailer(actually id do that after getting a known good shooter to try it) Im not sure how you will get on there...do they have any kind of accuracy guarantee?

If no luck there then you are looking at



Can I live with the rifles accuracy or lack thereof ?

Possibly bedding and or load development to achieve better accuracy.

Spitting the dummy and tardmeing it.

^^ This is good info.

The tension on the front sling screw that secures the forend is also critical on the BAR's, take it that this is the new "shortrac" model.

I have a couple of BAR's myself (a Mark II lightweight in 308 and a Shorttrac in 7mm WSM). Both of mine shoot very well (about 1 MOA or slightly less with loads they like - closer to 2" with loads they don't). I think the core point re making sure the scope is tight etc has been well covered but a few suggestions:

- make sure the stock bolt is tightly done up. This can affect accuracy quite badly if it is even slightly loose;

- not sure of your experience with crappy semi auto triggers. Although mine aren't that bad you need to put a lot more thought/effort into carefully taking aim and then following through with the trigger pull - it is not like breaking a 'mouse's thermometer' with a good crisp bolt action trigger;

- both of mine were fine, but I have heard of people having issues with BAR crowns;

- makesure you let the bolt run free into battery/close for the first shot (don't let it close slowly);

- hold the rifle firmly with both hands. Mine do not like bipods at all;

- try some more ammo combo's/different bullet weights etc.

I would actually be a little encouraged with 2" groups for factory ammo - I am sure with everything tight/the above checked and a few different bullet weights to try you will get close to an inch.

Be realistic - I know there are lots of people on google that report bolt action accuracy and 1/4" groups with their BAR's (!) - reality away from the keyboard is probably different. A few are possibly capable of close to this but most probably are not...

At the end of the day they are a semi auto designed for a purpose (quick follow up shots in side 250 - maybe 300 yards max). Even 2 inch groups are adequate for that purpose. My personal view is that if your hunting style regularly has you shooting over that range you may as well revert to bolt action - i.e. with careful/slow deliberate shots required to ensure regular hits at that range there is no or little benefit with a semi auto...

PPU, winchester super x, and lastly sst hornady. The scope is new, although its abit cheap, but Ive had them in the past with no problems.
Can anyone help a newby out a little?

Can you show a group for the "experts" to diagnose.
