The 5.56 is loaded to stand a little rougher treatment and water resistant because soldiers don't know how to treat anything nice,or get in out of the rain. ,,,sam.
Back to the original question. Are you sure your rifle has a 1 in 12 twist? Newer savages come with a 1-9 twist rate. The one I had a few years back had a 1-10.

i checked my twist by measureing how far the cleaning rod traveled until it made a full rotation... i measured from the tip of my bore brush to the complelt rotation mark.... i did it muzzle first till i got one ful rotation... please tell me were to find specs on this rifle..
the factory specs for the stevens bolt action seem to be a 1:9 twist rate i guess im wrong..... is that why i cant get a good group at 100yrds with my 55 gr ammo?

A 1in9 twist will stabilise a 55gr bullet.A 1in12twist has trouble with anything over 55gr. ,,,sam.
BartB says you can shoot a 62gr and so I believe some would work in a 1in12 twist.But not all bullets are designed alike and possibly you could find a 62gr that stabilised and a 55gr that didn't.Due to the heavier bullets having lower velocity and the fact that the longer the bullet,the harder it is to stabilise,the faster it must be spun.
What is the right twist rate for an AR15/M16 barrel? The below is from Corey Sattler of Olympic Arms. It will give you a good idea of what you should look at.[LIST][*]1x7 Technically too tight of a twist for any .224 bullet widely available, including the 80 grain. Manufactured originally to stabilize SS109 and/or tracer ammo, but further military testing has shown other twists to be superior. Some of the very heavy custom stuff (87 grain?) may work well, but why?[*]1x8 Great twist for 69-80 grain bullets. Sierra once informed me that the perfect twist for their 80gr was 1x8.2xxxxx (blah blah blah big long engineers explanation followed).[*]1x9 Good all around twist ratio. Best suited for 52-69 grain, but either end of the envelope will be questionable.[*]1x10 Practically the same as 1x9, but favors the lighter side a little more.[*]1x12 Great for the 40-52 grain bullets. Most often found on bolt action rifles as their primary use is varminting. All right for the 55 grain, but not the best.[*]1x14 If you want to under stabilize the .224 bullet, use this twist. Useless except for tumbling effect it causes upon bullet impact. IMHO, better to shoot straight with a good HP bullet as your chances to hit are better and damage will most likely be greater also.
Maybe this will help,but as I said,different bullet design in same weight may stabilise. ,,,sam.

Not necessarily. There are many reasons why you can't get a good group, some the ammo's fault, some the rifle's fault and most the trigger actuator nut's fault.
Assuming, just assuming, that their is nothing wrong with the Rifle and the trigger actuator nut, then one should look to the ammunition.
Fact: Some rifles just prefer certain ammo. It is always a case of experimentation to match ammunition to the rifle.
The way forward is to double check & confirm your rifleing twist and then try different ammo brands & different bullet weights.

How I was told to measure twist was to put a mark on the cleaning rod after inserting brush then mark the rod again after one turn then measure the distance between the lines instead of from the end of the brush but I could be wrong on that and please correct me if I am.

Yup and if you have some good freinds who shoot the same caliber maybe they could lend you a few factory rounds to test to save on buying unscrupulous amounts of ammo just to find the right round for your rifle
Yup to check your twist, use a sharpie (or similar) to draw a straight line all the way along the cleaning rod. Fit brush to rod and insert into barrel, Mark refernece point on the barrel, mark start point on the rod, draw/push the rod through the barrel for one or two revolutions and mark each revolution. Measure distance between marks and compute. This, of course, is easier if you have a ball-bearing type cleaning rod.
Ammo testing should end up like this:

Tried to answer your question.Sorry I caused you to feel indignant.Didn't know you knew so much more than I do.Please explain next time that you don't want an answer with explanation.I dont really care for your attitude and hope you feel the same.From the idiot that tried to answer you but just made you feel indignant. ,,,sam.
well sam, all i can say is your post confirms what I have already found, and that is, my 1:12 223 SPS varmint rifle shows more consistant tighter groups with 52 gr versus 55 gr projectiles.
thanks for the post

I do not feel the .223 rem is a sufficient round for large game. Also some states have a min caliber requirment. You should look into this before hunting large game with 223 rem.

the army uses them for large game ... i think it really depends on the type of ammo and your ability to aim in the right spot...how often do you see a round drop a deer in its tracks....? none its the placment of the shot that puts the deer down...ive got mixed comments on my ability to hunt deer with a 223 but i doubt i will doit

is that at 100 m? or how far close were you? i just wandering at 50 yards i get tight tight groups... im mean useing the same hole just about... but at 100 m or more i cant seem to get the group to even touch im useing 55 gr federal ammo but i have recently learned thanks to many helpful hint that my twist is a 1:9 rate but i am also shoting with no bipod or sandbags im laying up on my range bag so that might be the prob i dont know..... look foward to your reply...
