who has a 223 Remington VTR?

I do, and I am rather unimpressed with the accuracy of the rig - my M38 Mauser shoots better groups. But on the upside accuracy seems to be improving and will see once I try few handloads.
here few groups with the over the shelf ammo, have also tried 40gr Winchesters Varmint, and 75 grain handloads, they did about 1-1.5moa but only had 5 shots of each, so not really repeatable.
will handload these next with Varget and BLC2 (64, 69, 75 and 80gr bullets)

its got a 1-9" twist which should be able to handle up to 75gr bullets
why buy and expensive precision rifle and shoot cheap ####ty factory bulk ammo though it? It's like buying a ferrari and putting plastic 'Wal-mart special' tires on it. You'd get better results trading it in for an SPS varmint and using the remainder to buy match or premium varmint ammo. Or, better still, learning to reload (reloading is NOT time consuming if you do it right. In the time it would take you to run to the gun shop and back you could turn out plenty of handloads)
i'm actually going to start reloading, just don't know what bullets to buy and what grain? there is ssoooooo many to choose from:
like i don't know if i should get 45gr, 50gr, 52gr, 55gr, 62gr, 69gr etc, and also what type Hollow points, fmj, etc.

boat tail hollow point for long range target work, 60-80 grain (if you have a 1 in 9 twist or faster)
plastic tipped or HP varmint bullets (flat base or BT) for short range target (<300) and varmint use (40-55 grain)
SP's are OK for varminting but not great. Accuracy probably won't be the best either. The most accurate bullets tend to have most of the weight rearwords - which is why target shooters almost always use HP's - the HP there does little to nothing for bullet expansion. Plastic is also very lightweight and gives the expansion of a big HP, but without the extra drag.
FMJ for making noise.

Not correct. Target bullets are HP as a side effect of the manufacturing method, has nothing to do with weight distribution. If anything, a forward distribution would be better, as it would move the CG forward.
You are correct about target bullets not generally expanding well - they aren't designed for it.
I have a VTR not the same cal but it seems to like the Hornaby a-max bullet just under 1/2" group at 100 meters and that was with factory rnds now that i'm reloading i've been trying these silver tips from nosler i'll keep you posted.
Think about a toy top - most of the weight is rearword, that configuration generates the most stability when spun. A weight forward design would be more stable - except if it's sufficiently spin-stabilized, then the weight-rear configuration wins.
rear-weight is not a side-effect of HP design - a manufacturer COULD full the jacket completely with lead, creating an SP bullet using exactly the same tooling as for HP bullets. The air gap in the nose of an HP match bullet is there by design.
rear-biased weight puts the aerodynamic centre of pressure (CP) ahead of the centre of mass (CM) , which is inherently unstable. This then requires spin to stabilize (except in the case of flechettes and other fin-stabilized projectiles). The closer the CM and CP, the more stable the projectile will be, all else being equal. Even spin-stablized, a significant gap between the CM and CP makes for more precession and therefore more accuracy problems.
The hollow nose is a side-effect: a pin/punch drives the bullet out of the die, which requires a small hollow (for the pin to fit in). This results in a more-perfectly formed tip, less susceptible to handling damage, than would be possible with a SP type tip. Forming from the bottom-up creates a more-perfect base than with an FMJ, resulting in better exit from the barrel.
