19 to 21 grains of 4198. Check your loading manuals, too. Shoot light bullets....50- 52 grain

There are so many factors that effect accuracy.
Bore size (slugged)
Muzzle crown smoothness and shape
Rifling twist
Chamber and throat/free bore
How new the barrel is / is not
Is the barrel fouled? Jacket build up?
THE LOADS:
Crimp or no crimp?
How far is the bullet from the origin of the rifling?
Flat base or boat-tail bullet
Bullet diameter.( .223/.224?)
What primer?
What powders have you used?

My coyote load is 24 grains of Hodgdons Benchmark under a 50 grain Nosler Balistic tip, Federal brass and 205m primers. The load shoots great (under 1/2 inch) in my three 222's, and in the .3's with one of them very consistently. I load bullets to kiss the lands and use Wilson neck and in-line bullet seater dies with an arbor press. 222's usually just shoot, and you don't need bench rest reloading equipment to get great accuracy. The perennial old timer bench rest target load is as much IMR 4198 as your rifle can stand before primer cratering under a 53 grain Sierra flat base seated to kiss the lands or pushed hard into the lands. Try to keep bullet runout under .003" or less. .001" or less is best. If these two loads won't shoot, I think there must something wrong with your rifle, scope, or your ability to shoot.

FISH!!

Heed the words of Winston Smith in Orwell's 1984:

"Every record has been destroyed or falsified, every book rewritten, every picture has been repainted, every statue and street building has been renamed, every date has been altered. And the process is continuing day by day and minute by minute. History has stopped. Nothing exists except an endless present in which the Party is always right."

A friend has exactly the same problem with his Kriko in .222 R. He tried everything in handloading but to no avail. My advice would be to slug the barrel. While Kriko quality is high, I believe that some decades ago (<1990), bullet diameters were different : .222 R =.224 and .22 Hornet =.223. Rifling twist also differed and some makers did indifferently use the same barrels (.224 or .223) for both calibers.

3 shots do not make a group, they show a point of aim or impact.
5 shots are a group.

To measure true bore size, you push a soft lead slug trough the bore. NB : you may use a soft lead bullet from a slightly larger diameter.
