My wife has a Steyr Tactical elite, .223, 20" barrel 1/9" twist.
When we use 69gn Sierra Matchkings, and 25.5gns AA2520. At 100yards it's a one ragged hole group gun. Seriously, I won our club competition a couple of weeks ago with it, 10 5 shot groups, none over 1" big.
SMKs are however sometimes hard to get over here and expensive!
We shoot on a field-fire range, where targets are electronically resetting Fig.11 Fig.12 Fig.14 aluminium tagets dotted randomly over a mountainside in Wales
So we have some Privi-Partizan 62gn FMJs for use up there as we're only shooting big-ish targets.. http://www.prvipartizan.com/rifle_b.php
I weighed the bullets and batched them within .2gn.
However, no matter what I seem to do when we shoot these they are spraying all over the place, in the order of 3-4" groups at 100 yards.
Same brass prep, same day etc....
I used again AA2520 and tried loads going up .5 grain from 21 to 25.5(our SMK load)
I tried loading to the same length as the SMKs (as long as the mag will allow) and seating to the cannelure in the bullet, with and without a crimp from a Lee factory crimp die.
Still nothing like what the SMKs will group, even at only 100 yards I'd settle for 1.5-2" groups.
Can anyone suggest anything else I can try to get these things to shoot?
