Great article as always

I must just point out that Lias Issodon's bolter becomes Heavy 1 if you want it to rend as per the chapter tactics rule.

When using this rule, all boltguns, combi-weapons used as boltguns and bolt pistols fired are counted as being Heavy 1 weapons instead of Rapid Fire or Pistol type weapons for that turn.

It does say his is a salvo 2/4 weapon rather than a 'rapid fire or pistol type' so maybe RAW = he gets rending but it does say all bolt guns.

It's a shame. 1 potentially rending shot or 4 AP5 shots? I think I'd stick with the 4 shots.
