.223 newbie questions

Thankfully a shorter COL only reduces pressure in a necked case, rather than the increase I'm used to. Todays testing showed a best 50 grain group of 42mm, and 62 grain of 36mm. A little more on the COL should improve things, and a trigger with a less than 8lb weight has to help!

You've put the cart before the horse .

Firstly , regardless of how a case is sized , a reduction in c.o.l will cause a reduction in case capacity and an increase in pressure , not a decrease .

If you're trigger is so heavy as to affect your ability to shoot accurately, how can you trust your results . I suggest you sort the trigger then start again.

I'm not sure why , but you appear to be in an awful hurry . You say you're new to reloading and then have jumped in feet first .

If you're intent on doing seating tests , find the lands first , modern thinking suggests seating 0.020 " from the lands when doing initial development of charge weights . Though , magazine length may be a limiting factor as may bullet length if there is to be sufficient in the case neck . Then after charge weight tests do your seating tests .

My suggestion would be to use the bullet manufacturers recommended c.o.l .

You may struggle to get out to 800 metres as it's doubtful that a 16" barrel will give sufficient velocity for the bullet to remain super sonic at that distance .

Good luck , I hope you achieve the results you're looking for .

1 , read it before , have you sorted the trigger or developed forearms like Popeye?

2 , the title implies your new to reloading , which makes me wonder why start this thread if that's not the case ? Especially, since reloading principles are applicable regardless of chambering .

I suspect that what you really wanted was advice on powder choice and load data to suit your rifle barrel . If that is the case , then GRT is your friend, it'll also tell you if you exceed manufacturers maximum c.o.l by that I mean what they deem to be the minimum length of bullet in the case neck .

Regardless, I don't think I've posted any misinformation and was written with good intentions, so hopefully my previous post will be of use to someone who is a newbie .


Please share your results , it's always good to see a conclusion.

You are entirely correct. Title should have been ".223 newbie, questions"

I haven't gone through each post in detail, but in a 1:8 / 16 inch 223 for non target (varmints) a 60 gn vmax is a good bet - something Hogdon CFE
For target maybe 75 gn Hornaday
