[MAX7.62]

I always thought it was kinda screwy - I built a metric pattern rifle with a DSA bull front end with full float front grip etc. I figured that it would be the pinnacle single hole puncher. I made real sure to "season" the barrel good - fire 3 and clean - for 20 rounds. It grouped really nice - 1/2 MOA or so at 100. BUT, out of the L1A1's that I have, there is this one particular rifle that obviously has a really good pipe because it shoots pretty much the same group if not maybe a little better than the fat barrel. And you gotta remember, the L1A1 has a pretty skinny pipe!
Now, after all that, I recently (OK, about 5 months ago) got the "holy grail" for most FAL nuts, an Izzy heavy barrel. I was lucky to find this one, about a 99% rifle that appeared to be almost unfired. The Izzy turns out to be the single hole puncher out of the bunch. I forgot to point out that I load Sierra Match Kings and do any comparing between sticks with those. I figure it's a better gauge that doing a compare with surplus ammo, even the Portugese stuff which seems to be really good.
