.223 reloading
 

ok so iam reloading .223 rounds for shooting ground squirrels and i went to test out my powder measure and i get it set to the right weight then about 10 loads later i measure it and its about 10 grams heavy. then my second question does anyone have a good recipe for .223 i would like to use about 35gr to 40gr bullets but i have about 5 pounds of 748 ball powder so iam committed to using that powder. any help would be appreciated!!!!!!

I measure every single load I make for all my rifles that way I know there all the same. As for the 748 ball powder I've never used it. I run IMR-4895 with 68gr hornady tips in both my 223's and they love it.

i wouldnt have a problem with measuring every round for the right amount of powder but considering the fact that i have 1,100 rounds to load i think that will get really old really quick. and does anyone have a suggestion for primers, should i be using magnum or just normal primers?

I use standard small rifle primers on mine (CCI 400's) a friend of mine was reloading for his 204 ruger using the same powder as i do in my 204 ruger, he loaded his a little hotter then I load mine but with magnum primers. His chronyed on average 150 FPS slower then my with standard primers.

I also weight each and every load...I have never found a powder measure I trusted enough not to weight each load...and I know how you feel, last summer I loaded 7500 rounds of .223 over a 3 month period.

I use Win 748 as my primary primary powder for my .223...but I don't load anything that light. All my .223 rounds are 50g Nosler Ballistic Tips (the varmint ones)...for this load I use 25.5g of W748 with Remington 7 1/2 primers.

Oh...it also makes a difference on primer if you are loading for an AR15...if so you want either the Remington 7 1/2 primers or the CCI 450's.

i have a bolt action weatherby so i dont have to worry about the semi-auto thing (although i wish i did have to!!!) and thats what i have been using was win 748 powder and then does anyone have any more suggestions for the bullet weight that i should be using, thanks.

That's a new one for me. Never heard of having to use Magnum primers for an AR. Just curious why that is.:)

Both my 223's are AR's and i use CCI 400's with no problem.

but it wouldnt hurt to use cci 450's right, keep in mind i dont have an AR

yes you can. just start your loads below max and work your way up looking for pressure signs.

k, then what are the advantages of deburring the brass does it just make bullet seating easier or does it just make the bullet seat a little bit straighter in the casing.

Both. But, you have to keep an eye on overall case length as well. Do not allow your brass to exceed the allowed max length for it can cause jamming, failure to fire, or explosion. Do you have a case trimmer? If not, get one. You will need it if you plan on loading your brass more than once and you are using any brass other than once fired.

no i dont have one but i have a deburring thing but its hand held thanks for the help

All that deburring tool is going to do is chamfer the case mouth and allow easier loading of the projectile. It also allows the bullet to enter without the square case mouth shaving off copper jacketing while loading. You will still need to monitor the case length after firings. For that you will need a dial micrometer or case length gauge.

Your powder thrower should sycle 748 pretty consistantly. The trick is to use the same technique every time. Such as after cycling, lift the handle slightly and tap it down. This lets the powder settle in the charging drum.
That being said, I normally weigh each charge too. But with you charging 10 cases and checking your weight you shouldn't have a problem provided you dump the previous ten back into the hopper if your weight is off when you check. Even if the weight is OK, a visual inspection of the filled cases SHOULD be made before seating a bullet.

I don't shoot bullets that light . But I do shoot a lot of 50 & 55 gr thru mine , have shot nothing but 748 for years, and the standard load of 26 gr is a great starting point, right out of the reloading manual. That load is all I shoot thru one of my contenders.

Pretty sure you mean 10 grains. That is still a hell of a change, I'd definitely weigh each charge until you've got it consistent.
