Hi everybody I'm new here and I have a question, I have a savage 110 that I reload for , I use a 180 grain hornady interlock over 48.7 grains of imr 4064, remington brass, and winchester primers. At 40-50 yards I can put 3 rounds touching each other but at 100 yards it opens up to about the size of a baseball. I was thinking the rounds should stay tight or pretty close like they are at 50 yards. Maybe it's just me , but I use a good rest. Thanks for any suggestions.

Hello.

If you have not already, check ALL screws on the rifle...make sure the stock screws are tight but not too tight, make sure all the base and ring screws didn't come loose...also inspect your rings with a magnifying glass for hairline fractures...that's all that comes to my mind other than maybe try a different load or twelve.
Good Luck. I hope you get it worked out.

You didn't say if you were using a scope. If so is the scope of good quality? That can make a difference.

I would also try a few different loads. I have a Savage 110 in 30.06 and it will do 1 1/4 inch groups at 100 yards all day without even trying hard. I did have to glass bed the action when I first got it though.

cdc: 48.7 of 4064 is a grain and a half short of max for that powder with the 180 gn bullet, so sez my old Lyman manual but is half a grain heavier than the factory velocity duplication load for that powder/bullet combo of 2666'/sec.

Accuracy loadings from my manual include IMR3031, 4831, Rx21 and IMR4350, but not the 4064. I recall trying that powder for accuracy loads in a buddy's 7400 and not having the success I thought I should have.

I would first check everything on top of the rifle and make certain all screws are properly tightened as 7magWoodsman advised, and then I might try an different powder. HTH. Mikey.

Professor Fuller, 1 1/4 at 100 and your happy with that?

Time for a new load ma friend...If my 30.06 couldnt get 3/4 moa at 100 or better id wrap it around a tree and buy a new one :oops: ok I wouldnt wrap it around a tree but lawd Id sure get rid of it... CDC.. The savage 110 is a great gun out of the box I would do like everyone suggested and check all your top equipment...Also make sure you are on a stable rest and check your form...That load is just a mite excessive though with that combo...Id try backin it down in half increments and do a lil range firin till you get one that your rifle likes to eat...Also...Are you allowing enough time between shots for the barrlel to cool down??? Thats a MAJOR killer to accuracy...Good luck and shoot often

Typically(although not always) a slower burning powder best suits the 180gr. bullets in 30-06. If you can, you may try a slower burning powder like IMR or Hogdon 4350 or the 4831s. Good luck

I agree with High Brass on the powder. My '06s are more accurate with H4350 in the 150-180 bullet weight range. However, the size of your groups suggests a mechanical problem and the scope/mount is the first place to look. Also, check the guard screws.What shape are the groups - spread out horizontally, vertically or in a circular pattern?

cdc · « **Reply #8 on:** September 02, 2004, 08:53:08 AM »

lilabner, I'm getting more of a circular pattern at 100 yards, but the pattern is dead center and about 2 inches high of my target. When I get a chance I will check to make sure everything is tight like everyone has suggested. If I could just get that group to shrink a little bit that would be nice. Thanks for everybodies help.

cdc,

I agree with the change of powders. I have found that the best accuracy comes from H4350 or H4831(I prefer the short cut) in my .30-06's. I see no reason why your Savage shouldn't be shooting MOA or closer groups. I have found that most newer .30-06's get their best accuracy with bullets between 150 to 170 grains then the groups start to open slightly. Let us know how you are doing. And by the way Welcome to Graybeard Outdoors. The very best forum on the net for hunters/shooters going today. Small groups and tight lines to you. Lawdog

Sounds to me like he might have his scope mounted way too high off the receiver compared to the muzzle, center to center.

Does not make sense touching at 50 but baseball size at 100?? Outside to outside at 50 yds should be .6 inches right if all touching, so 100 should be twice that outside or 1.2 inches. If it is bigger than this maybe it is you. What kind of rest are you using? Are you using iron sights? How much shooting have you done at 100 yds or better?Jimmyp

tbmaker · « **Reply #12 on:** September 02, 2004, 05:11:35 PM »

I with the thought, parallax?? What is the scope in question?
Groups should be more half hazard with loose equipment.
It also makes sense about powder changes, I don't handload but each load in my rifles shoot some where else with the same bullet weight.
Two strong avenues to pursue.
Just my 2 cents.

Since you are rolling your own, try some IMR-4831 and 180Grn Sierra Game King SPTB's. This may or may not be the bullet you stick with for hunting, but I've found the GK's to be the most accurate bullet I've tried so far.

I'm getting SUB MOA out of a Browning semi-auto 30-06 with this combo.

Good Luck
