Shooting a 223 to a Mile Accurately By Jerry Teo

I use a sized case. Headspace will not affect your accuracy as much as using proper dies, keeping runout to a min, and most importantly.

Weighing your charges precisely. Most scales have too much error to be effective with the 223 case.

It is best if you can get the differences between charges UNDER 0.1gr. Most scales have an error range of at least 0.2gr

This and watching the conditions will help shrink the groups on any 223.

Good luck.

Thanks for responding. I don't even have a chronograph, and was just using a powder measure. The H380 for the 250 probably stays more consistent than the extruded varget. I made a bunch of rounds to break in the barrel with. The groups were more sideways spread than vertical, but I'll have to see what it will do with weighed charges. I wasn't sure if it was normal to use a sized case, and shilen recommends a go gauge. Thanks again Nathan

As long as the case is a proper fit to the chamber, it can be used.

Drop your case into the chamber and it should sit so only the extractor groove is out.

Glad you liked it.

Was out shooting yesterday and gusts were at least 20mph. The weather channel was reporting winds in my area up to 40mph.

The birds were walking

Since we were at the shooting spot, what the heck - sling some lead down range.

to our surprise, both 75 and 80gr Amx did very well in this gale. I held as much as 16 mins at 800yds but we were able to get bullets close to and hitting a milk jug sized rock.

Of course, we were bounced around with some shots missing by several feet when a strong gust came through but given more time, you would get a feel for how much to lean and it was not hard to get bullets on target.

It was so much fun...

The scale I am using is the Jennings MACK20. Working very well, readily available and very well priced.

Keep it clean and level. When you get the feel of this scale, you can get your Varget loads to within one or two kernels of powder.

Close enough for me

love reading this article. i have always like the .223 round. i have built a rifle with 1/8 twist. the 75gn amax round you talk about has caught my eye. i have shot some hornaday 75gn that has reacted really well to another rifle. im not making this rifle for match shooting, but i do beleive in accuracy. if your gonna shoot, shoot to hit what you aim at. ive had chances to shoot coyotes at ranges of 700yrds. and passed on them cause of the light 55grn rounds i have been shooting, and of course i would upgrade the glass too for long range shots. i guess im just curious on the grouping on a 1/8 twist barrel with the 75grn amax at 500-1000yrs.
