Hey there,

I am very much used to reloading archaic ammo, with wonderful results. I have only one modern cartridge in the hoard and that is the new fangled 223 wssm in a model 70 short action. For two seasons I bought factory ammo, only to get the cases, however I noticed when I was using the factory ammo Winchester 55 grain the cases came out black as shoe polish, in other words a lot of gas coming back. So I delve into the world of reloading the 223 wssm, what a pain in the ass, had to modify shell holders and also the priming tool, none the less. I slapped on a new scope and off I went to the range. Fired 3 rounds of my handloads and each one came out in nice shape no gas, or discoloration of cases, however the bullets are flying of to the crab nebula. another 3 rounds same thing not even on the paper. so the target gets bigger and still there going off to the moon. At this point I am starting to get a little miffed. Look to see if I have loose screws nothing wrong, however I find three factory rounds through the rig, what the heck throw them through the gun and all three land on the paper, not in the bull to be expected as the rifle is not zeroed in but on the paper and black as shoe polish. Hmmm I say and throw 3 more of my rounds through and of course they come out clean but the rounds are going who the hell knows where. So what am I seeing here. I reloaded a little lower than I normally do, but this is a bizzare scenario I ve never dealt with. Short of sticking a huge piece of paper up really dont know what to do. I live very rural and exotic powder is not on the menu. IMR 4350, IMR 4320 and IMR 4895 are on the menu, might even have a few cans of IMR 4227 kicking about. Any suggestions from the 223 wssm shooters out there.

many thanks to all

keep the blue sky up when your flying
and make sure your knees are tucked and together when you land
 
You didn't mention the distance that you were shooting, so I am going to gather 100yards. For whenever you are unsure of zeroing a scope, I start with a boresighted gun, at 25 yards. Once you are on paper there it will generally get you onto paper at 100. without having any idea where the bullets are grouping, or how tight they are grouping you have no reference to how accuratly you are shooting. You might have a really accurate load and not know it. From the powders you have listed and you mentioned using 55grain bullets, according to the Hodgdon website, IMR4350 should be the most promising, with a starting load of 44.9 grains. See the link below;

Without more information from you, how you are resizing, or what powder charges you are using (is your scale zeroed correctly) it would be hard to diagnose anything else.

Hope that helps
 
OP, first thing is to make sure you are on paper. Start at 25yds with a big sheet of paper and get it sighted properly with the factory ammo. Then try your reloads, still at 25yds. If they are still not on paper, move the target to 15yds, then 10yds if necessary. You have to have a known starting point before you can do anything else.

You didn't say what bullet weight and brand/type you are using or what your rifle's twist rate is. If you are shooting light bullets very fast out of a fast twist barrel it is possible that the bullets are exploding before they hit the target. If you are shooting heavy bullets slowly in a slow twist barrel they could be tumbling and missing the target. The only way to know is to get close enough that you are putting holes in the paper.
