I don't think I've ever seen any 243win group that bad.
I second the recommendation of shooting some factory rounds through it.
The Winchester Supreme ballistic silver tip ammo has shot very well in every 243 I've seen and the Nosler 90 grain ballistic tip ammo is very consistent as well.
If you haven't allready I would go over all of you fasteners to make sure nothing is loose.

I originally posted and then noticed you have another thread already with tons of posts.
I am a little confused on your charge weight. Why are you at the minimum of 4350?
Have you tried increasing the charge in .2 or .3 increments and shoot a 3 shot group
At each charge weight? You may need to speed that bullet up to get it to stabilize.
If I wanted to check on some groups, I would get some 75gr nosler and start at
The book minimum and go up from there in .3gr increments shooting 3 shots
At each weight until I found the best group and then play with bullet depth.
Waiting at least 3 minutes in between shots and maybe 5 minutes between groups.

when I had the factory Remington barrel on my rifle I shot 100 grain soft points out of it factory Winchester ammo always grouped well and when I reloaded for it I ran 95 grain TMK with 39 grains of N550 or H4350 both worked well N550 is a little more accurate. after I switched to the McRee barrel all I do is reload and I use the same two recipes and it shoots awesome. I’ve found every 243 I’ve shot to shoot sammi spec seating depths very well
With the ELD-X bullet you want to be as close to the lands as you can so just seat out as much as possible so that the OAL still works through the magazine well . Then set about cleaning up your shooting style . You can't effectively tune a load when the basic shooting accuracy is all over the place . This is not meant to be picking on you at all it's just the way it works . Sometimes getting a more experienced shooter to help you will pay big dividends on the target and they can also check out your gun as others have mentioned . If you are shooting of a bench I am fairly sure that what I see in the groups is inconsistent delivery and poor set up . More information and pictures of your setup might help diagnose things better .
You say you have done lots of experimenting
Have you done an OCW or a ladder test?
Could you provide more info?
Barrel twist, length,
Brass, primer, powder (we know) charge weight, bullet. Distance tested
What is your method of loading? Single stage, or?
Thanks

Yes i am shooting at 100 yards to get a load, I have tried every bullet length and powder combination 2 times. One day ill shoot a 1moa group the next week with same load will print a 4 moa group using the same ammo from the week prior. Action has been bedded and barrel fully floated with over 1/8 clearence from muzzle to action. Checked cold and warm. Forend has been completely filled with epoxy to stiffen up. Scope base, rings have been checked and torqued and locktight to spec. Scope is a swfa 10x42. The groups above from today are all the same powder charge. The same charge shot from the week prior that held 1 moa, thats the one 0.050 from the lands. This week it was a 2 or 2.5 moa group. Almost every group has mystery fliers for no apparent reason. Also taking advise from others on here i cleaned my bore squeaky clean and it didnt seem to help. Kept cleaning till there was no blue and clean bore. Actually tomorrow i will be heading back to the range again. Afterwards i put over 120 rounds through the barrel 20 Remington corelocks and 100 90gr eldx. Just am stumped and ready to give up on it.
Loading is as follows
Starline brass- trimed, flash holes done and primer pockets trued up.
Federal match primers
H4350 powder
90gr eldx bulles
Deprime then run through ss media
Dried in lyman case dryer
Fl size die bumping shoulders back .002 ( expander ball removed)
Necked sized in madrel die- Sinclair die
Trimmed case length
Prime
Graphite lube inside case necks
Powder charge- rcbs charge master.
Seat bullet- hornady custom dies with micrometer
Using single stage press
Rifle info....
rem 700 sps V
1-9.125 twist
26in heavy barrel

I second this. If the same loads shoot good one day and bad the next at 100 yards, I’d start looking at the scope/scope base/scope mount. Make sure the scope is level and the rings/base are not loose. If you can’t tell for any reason, I would remount it. Also, not sure how experienced you are with reloading but if using a (non lab) digital scale, double charge check weights on a second digital scale or use a non digital. If all looks good, mount a different scope if you can or send yours to the manufacturer to inspect.
Something is loose. May be a bad scope maybe rings/mount or muzzle device. strip it down and torque everything down again trying a new scope.
That one target with the two decent factory load groups and then it all goes big... something is not right
Agree with the comments of possible bad scope.
Are you shooting off of a bipod? Which one and what surface? Rear bag? Don’t change them always keep those variables the same.
Also take a good look at the crown. Make sure nothing has happened to it during cleaning.
Do you have the ability to get another shooter, one who is “a good shot” to shoot a group? Just to eliminate you as a potential issue.

I think i finally figured it out, went ti the range with 20 rnds spit into 2 groups of the same load and shot 10 rounds which is the far 2 right top red dots with my swfa 10x42 scope, results were the same as before. Then i switched scope and front and rear rest and fired the lower far right dot also and again same groups. So out of frustration i grabbed my torque wrench and tightened my action screws to 65 in lbs. Which i thought was to much but ohwell, try it i thought. I fired the group on the lower black and green target. Group was fired with a warm barrel and didnt exactly take my time as i was frustrated but landed 4 shots right at .750 moa with one flyer..... i cant believe this whole time my actions screws werent tight enough. I followed the reccomendations of 45 in lbs. Guess it needed more.

Now i just need to find a different bullets, with my 7mm using a max and now using 90eldx in the 243, with both bullets i got random fliers like this... i always used hornady bullets but after the last few boxes i think they need to look into tightening up qc or something...
Do you fellas think i would be able to stabilize a 105 nosler custom competition??? I heard of yhe hornady 105's working out ok... or maybe someone could reccomend a good heavy for caliber suitable for a 1-9.125 twist and 26in barrel?
Nosler states 8 twist.
Why not try some 75-90gr bullets
There is a YouTube video with a stock savage shooting
300-500-800 yds with a 58gr bullet.

I just always found best accuracy in every rifle i have ever owned woth heavy for caliber bullets, was even true for my rem 7mm mag, rem 700 bdl 300 Rum. It like 220 grain, kicked like a mule though. 375h&h liked 350 gr. 45-70 liked my custom noe mold cast 437 grain wfn bullets. So just kind of following what i know. Want to shoot 105 gr. but don't wanna waste the money if they wont stabilize. Longer heavier bullets with acceptional bc will provide better ballistics and wind resistance at distance than a shorter lighter bullets. I just found a killer deal on the 105gr. Nosler custom competition bullets, with having a 26in tube i dont know if i can push them fast enough to stabilize. Next year i wanna rebarrel but just need to make due with what i have for now. If they have a longer bearing surface than say a berger or similar vld style bullet i think i would be ok....
Throw some N550 or H4350 behind them I have even used N160 behind them makes for a full case of powder H1000 is a great powder as well full case them 105s I’m sure will be fine in a 1/9 twist I’ve shot 115 dtacs out of one that measures 1/8.4 and they shot great.
If you need 65 inch pounds to make it shoot better then you don't have a stress free bedding .
The flyer is still opening the group to unacceptable so are you sure it's you pulling a shot ?
If it's a wood stock or a weak plastic stock with no pillars 65 inch pounds could lead to either crushing the stock or cracks eventually .

Well i dont see how it cant be stress free, when i bedded it i didnt torque and screws down. Just sat the reciever in the action and used blue painters tape wrapped at the front and back of the action to hold it. Unless there is a way to see if the action is stressed, guess ill never know.
Place the gun on it's side on a table and slowly release the front action screw if the barrel moves up out of the forend channel even a few thou , then that's the amount of stress present .
Did you allow for clearance in the right places for a Rem 700 ?
I already posted it . On a Remington 700 action there should be clearance under the recoil lug and also at the sides of the lug . Also probably a good idea to have clearance at the back of the tang .

After finally figuring out my problem a fellow snipershide member has helped me out and this group was shot with factory Federal 80gr soft points, measures right a .500in. It was a 5 shot group. Now i am excited to finally be on the right track!!!! Thanks Again OG10!!!
