H-335 gave me simular results running the bullet out about .020 or a little more than would fit in the mag .
Still gives you two shots .
Some time ago had a 1/12 Olympic Arms ultra match and later a 223 Wylde 1/8 was able to get good accuracy with both .
Can’t remember the particulars but got notes somewhere.
The factory stuff ran about an 1” give or take on various days.
The Wylde 1.5”
I know that’s sounds contrary to logic .
That Wylde barrel just wouldn’t shoot with the ultra .
