Not shooting well enough to hit the V-Bull

The thingabout moly as well, is you have to ge the pressure up to get it to work the same as an uncoated bullet, so typically the bullets are jammed to the lands to get the same and consistent velocity as with uncoated bullets.
i have not messed with moly for quite a few years now, but if you PM maynard, I'm sure he can give ytu the whole skinny on it.
One thing i do rememeber aout it was I cleaned my gun with solvent while using it - BAD move.....!:eek:

I didn't catch the moly coated bullet part.

Some things are a little different when shooting moly. If you are starting with a clean barrel it may take up to 20 rounds for the barrel to get properly coated and the groups to start to settle in. My cleaning method is not to clean until the groups open up. I have gone over 800 rounds without cleaning and still won matches. When it does come time to clean I use a foaming bore cleaner and clean down to a bare barrel.
A friend of mine also uses Moly and cleans every day with 2 patches of Kroil and 2 dry patches.
 
Still not grouping well enough to hit v-bull at 300 Metres, but looks promising.

Ok I tried mystic`s load and overall length. I do not have a gauge to measure runout, nor the patience to weigh each load on a lee safety scale. Nor did I sort my brass by headstamp and weight. However just reducing the charge weight reduced my vertical dispersion a lot. I was getting a weird pattern Two rounds would be close together and then the next two would be close together as well but impacting at a different spot on the target. Barrel heat? Shooter error? loads? or I just do not own the mystical savage factory that shoots in the twos. ? :)

At least sort your brass by headstamp. Fine tuning is all about eliminating variables. There are big variations in case capacity between manufacturers. You'll never stop chasing your tail if you don't eliminate the big variables, so that you can see the impact of the smaller ones.
 
If you are serious about shooting small groups you need to pay attention to the small details in your reloading. Varget does not meter well with thrown charges. While +/- one or 2, tenth of a grain won't matter in a hunting load of a larger caliber, with the smaller cartridges like the .223 you need to be a little more anal about how accurately you make your ammo. Everything that you can control, weigh and measure will make a difference with the end results.

If you are shooting brass that has a 2 grain difference in weight that difference could be in the web of the case or in the thickness of the case. This will result in different pressures and velocities and different POI on the target.

Barrel heat can also be a problem. Match conditions in a fullbore/F Class match with a fast marker and a fast shooting partner, could have you shooting one round every 30 seconds. If you have a slow shooting partner and a slow marker, shooting 3 to a target you will be lucky to fire one round every 2 minutes.
