.243 Accuracy

[fastrac10 0]

I have a Sako 75 .243 and having a bit of the same bother. I have a Sako Quad .17HMR that will group less than an inch at 100yards any day of the week. I bought the Sako 75 on the back of that. I use Sako gameheads 90grain for deer and it can be around 2inch groups at 100 yards - which still gives a good kill zone, but not good enough for me to take longer shots at foxs say 150-200yards. I have just bought some different ammo to try for foxs 55grain. Mine also has a T8 on. I wonder if there any more people out there having trouble? I will watch this with interest - as you say the rifle might have to go if this doesn't get sorted!! Good luck!

Sorry to hear that you are experiencing the same issues. Ironcally, my best results are with the same ammunition. If I do find a compatible factory round I shall let you know.

 

Many thanks for that. The Sako gameheads I was told was very good factory rounds and idea for deer, but should give sub inch at 100yards.

Snapshot have just noticed a very slight mark on the barrel, at the forend and the left side. Maybe the stock has caught this. Looks like a trip to gunsmith to take a little off the stock, although the barrel still looks like it's free floating! This could be the problem?

the sako's and tikka's in .243 have a one in ten twist rate some will shoot 100g some won't just depends on the rifle in question, firstly,

take the mod of, and fire a string of five shots,

As if the mod is sus this will ingrease the group size....

 

try a few groups with the mod off,

 

Do you use a good copper solvent, as copper build up may be a problem......

 

are mounts tights rings, etc,

 

is the barrel free floating....

 

i shoot 95 grain sst's and 95g nosler partition's to great effect on deer, accuracy about 3/4 inch to slightly less at 100 yards.

 

the sako 75 is an excellent gun and should shoot way beyond the 2" group mentioned,

 

let us know how you fair out.....good luck.

 

 

No noticeable effect with or without the mod, other than the point of impact moves 1" up and 2" to the right. I use MPro cleaning solvens etc and clean the barrel thoroughly (no sign of copper fouling) and religiously between sessions at the range.

Can't remember the name of one of the solvents I use. The other is the bore foam, and that works well. You'd be surprised how much can be there when the barrel looks spotless so worth trying a different solvent, leave overnight too.

 

Sako 75 should be shooting sub half inch with the ammo it likes, I had one in 22-250 and if I didn't get a one-hole group I was mighty miffed.

 

Regarding the ammo, you can use 85gr Federal on deer, that's what they're designed for and they work well.

 

Failing that, if you have to go really lightweight, I might be in the market for an accurate 243 fox rifle

 

AFAIK there are some 80gr PSP loads that would be worth a look too.

Many thanks. I shall try a differtent solvent. It looks like I will need to try a lighter round to prove the accuracy, one way or the other.

forrester bore foam is good but used sparingly, KG products are also good but hard to come by in this neck of the woods.......

hi mate get a note like £20 and slide it up the barrel. i done it to my 22/250 and my annie hmr which has wooden stock and it go's right up to the action with out touching you no it is fine then. check the stock screws on the rifle and mounts are tight. just take your time between shots.

 

the kg stuff is very good cleaning stuff. get the black powder one and the kg12. best thing to do is get a couple of people to shoot it and see how it groups then. also use some lighter rounds as it depends i guess what twist your barrel is

[Deker 3,478]

Never could get on with the Bore Foam...still got 3/4 of a can...each to their own!!

[martin 332]

What I suggest is,sell the rifle to me cos I am after a dodnor action for a project I am gonna be starting soon.....martin.

Thanks for that Jamie, a £20note slides up the barrel fine. All screws seem ok, so going to try a group with mod off to see what happens. As I said before there is a very slight mark on the barrel at the fore end so not sure how it got there - did buy this second hand. I take it the £20note should still slide up there when it's sat on it's bypod - I checked it with someone holding the rifle. Thanks again

if the stock is soild on it mate no need to try it up there then when on bipod as the stock wont flex. i have a mark inside my 22/250 about 3inchs from the muzzel end and i was worried but it still groups fine. your be surprized if you put a borescope down a factory rifle how ruff the rifling is

I have a SAKO 75, Schmidt 8 - 56 in .243. And pased my DSC1 with a touching group in the centre of the 4" target. I always use Norma 100grain ammo. I know this will sound silly, but I have found I shoot more consistantly off my bipod than I do off a sand bag. The latter I have only tried once and could not be consistant with my grouping. Being from Devon, we only use £5 notes to check barrell clearance. Good luck.

[philip140 6]

some rifles really come to life with some for end pressure. free floating a barrel usually helps most barrels especially thicker varmint type barrels, but occasionally a bit of for end pressure on a sporter barrel can tame vibrations and tighten groups -try it, you have got nothing to lose!

to start, just get a business card and unscrew the action screws so that you can slide a business card under the very front of the barrel and stock and re-tighten the screws. if there is too much clearance between barrel and stock, try 2 layers, or try 2 layers anyway and see if more pressure helps - you may be surprised!

if it works, try using a strip of plastic and perhaps glue it in place to be more permanent, or just oil the card.

 

give it a shot and let me know!

Had a Tikka 243 new. Could not get it too group at all. Tried every thing ,strip,clean ,back too shop,mod-on,mod-off, back to shop, back too range diff ammo ,back too shop,bi-pod, sand bags ...........ball-bags too this I thought, back too shop. In the end it became heated with the supplier as they now blamed me a walk through the garden off understanding we comprimised and too cut too the quiuck I now have a Howa .

I have since heard that the 243 for this make is a problem round for whatever reason. Down the club a number off members have heard off grouping problems with the Tikka/Sako. Hope you sort it out. It can be hard on your confidence, don't let it get that far have it back too the supplier.

Well as you know anything can be faulty, good luck with it, i hope you get sorted.
