I have one of the Remington R-15 Vtr's and the best group of 3 i can shoot at 75 yards is about 2.5". I use a hyskore gun rest on a stable bench, so steadyness is not an issue. I reload 21gr of IMR 4198 behind a 53gr hp to around 3100fps. I also made up a few loads of imr 4320 with 25 and 27gr. these loads shot in a 3" circle... I talked to a gun dealer and he said they should be a 1" gun. My question is, do any of you have this gun? Does a gun with a 1:9 twist need a heavier bullet than the 53gr i am using? I have also shot 55gr sp and hp wolf ammo with an identical outcome. would there be a chance the rifling is messed up from the factory? Any help would be greatly appreciated!

you using iron sights?

Twist is fine for the bullets you are using. What scope/sights are you using? I can't imagine it would shoot that poorly.

Well, it IS a Remington...anything is possible.

If all your groups look the same, regardless of load, it's not the ammo.

Either you have a barrel that's taking it's own sweet time getting broken in or you have a factory OOPS! somewhere.

I had a Bushmaster (same company now as Rem) whose barrel was loose, straight from the factory. It'd make a *clunk* noise when you pushed the muzzle side to side. It does happen.

scope is a Tasco 6-24X60E-SF

buy a few different brands and weight of bullets. itll take a lil bit to find a load the gun likes.

Although I dont think ive ever seen a 223 that couldn't print better then 2.5inch @ 75

Sounds wacky to me, too. Try some Black Hills 52g HP Match ammo. Even my $200 H&R shoots this well.

Another thing to try, switch the scope to one from another gun that shoots well. This will eliminate the scope.
I've had Leupold scopes fail. NEVER overlook the simple solution.

I have a Colt CAR A3 which is a similar gun. I'd point the finger at the scope. I use 69 Gn SMK's in mine over Varget or BLC-2 and it's a very solid 1" gun. I'll find my numbers for charge weight and get back with you, but it's certainly not a max load.

I have a Rock River Match HB AR 20" 1:8 twist and a Bushmaster M4 1:9 twist and have done extensive testing on these rifles. I would suggest 60 Sierra Varmint HP #1375, this is a great coyote bullet and will work better in you 1x9 twist barrel. This is the load I use that is closest to your IMR 4198.
60 GR. SIERRA HP, 21 GR. (Hodgson) H4198 WW BRASS, FED MATCH PRIMER, OAL 2.266”
5 SHOTS .388” 3 SHOTS .251”

**My pet coyote load is 26 gr. Varget, 60 gr Sierra HP, WW brass, Federal match primer.

**My accuracy load is 25 gr. Varget, 69 Sierra Match, WW brass, Federal match primer.

The Rock River shoots .5" and did right out of the box. The Bushmaster is a 14.5" Barrel and it will shoot 1" if I do my part at a 100.

I also agree to try another scope... just to be sure.
I have tried alot of different powders: Varget is by far the best overall powder I have found. The H4198 worked better for me with lighter bullets. Benchmark also did pretty good. I would work with loads and shoot the rifle some and see if things get better. Good luck, jbok

my remmmy seems to very much favor the 63 gr sierras with H335. I suspect your problem is more in the tasco than the rifle.

Well if its the scope, then i prolly got screwed. I think i bought that scope on ebay for over 200

update info:
I Have tried two additional scopes since... Same outcome. I haven't been able to reach a gun tech at remington yet. I called a few gun shops and gun smiths, they told me that may be all the better that my gun will shoot. He said factory bbl's are usually cheap and you can have three shoot really well and one shoot poorly. one guy told me it may need a heaver bullet (68gr). I am going to try a few loads with a heavier bullet and see what happens.
thanks

May be the ammo, may be the gun.
If it won't shoot a 50g +/- weight bullet in a 1:9 twist, it probably won't shoot a heavier bullet any better. However, I did shoot fifteen different brands and weights of factory ammo in 3 different rifles a while back.
A 22" H&R Handi-Rifle (unknown barrel twist, 1:12 I think), a CZ527Varmint (1:12) and Bushmaster XM-15 (1:9 14.5" barrel--16" with muzzlebrake).

Most of the ammo grouped fairly well in all 3 rifles, some did not. One of the best in the Bushmaster and H&R was the 62g Wolf HP believe it or not. It grouped as well or better than BH 52g Match HP, BH 50g V-Max and BH 40g Nosler BT (no longer made) as well as the other brands of ammo including: Winchester 45g HP Varmint (Wal-Mart white box of 50), S&B 55g FMJ, Remington 55g SP and FMJ, Federal 55g SP, etc).
All of them shot AT LEAST as good as your rifle does.

I believe it was a factor of the right "barrel harmonics" rather than bullet weight, because the Wolf shot just OK in the CZ and the CZ will usually out shoot me.

One that worked very well in the CZ was the BH (red box-new) 60g V-Max. I know a 60g bullet usually needs a faster twist, but this ammo was under 3/4" @ 100 in my 1:12 CZ.

So you tell me why a 62g bullet was marginal at best while a 60g bullet shot very well in the same rifle.
