I have the same thoughts as BC. There are reasons why a 3 lug is
better than 2 lugs.
I can tell you one reason why the oppoisite is true, what can you tell me to support your opinion?
Well,my understanding of a 3 (position 2 o'clock,6 and 10) lug bolt is to reduce bolt lift
from 90 to 60 degrees and
relieve case side thrust, depending the lugs are lapped even. Most of factory cases have
.003 to .005 run-out. The thin side will become the long side and thick side will be the
short side when fired, causing the case to flex to the side. A 4 lug rifle will improve this
condition even more (position 12,3,6 and 9 o'clock).. Check run-out on a case fired
with a 2 lug rifle and than check a case fired with a 3 lug rifle. Which one has flexed more
than the other. Which ever way that case has flexed is the way the bullet will
print on the rifling and will not be true centered.
WHAT IS YOUR OPINION ON 2 AND 3 LUGS?
