Just posted a reply to another thread on A5 vs. HTG here...
McMillan A5 or HTG
But the same answer applies here!
YES on the A3 [McM] as an all-round stock...at least it works for me!
The forend is not so wide as to cause a problem being in the hands all day but it adequatly rides the bags on a bench.
Just my 2 centavos worth...adjusted for inflation!
