OOC: Deathwatch Core Rulebook states the Heavy Bolter weights 68 kilos alone. Heavy Bolter shells are closer to 1-1.25 in calibre, and the need for Astartes to carry the ammunition in a large backpack (as in here ) that could be holding hundreds of shells (anything less would mean the weapon would run out of ammo in a ridiculously short amount of time), means that the whole switch to a Heavy Bolter would add somewhere around 200+ kg. At that point, Ragnar will barely be carryable.

It will also need to be taken into account that Blackmane wolves are not normally ridable, despite standing up to a Space Marine's shoulder. It is only Thunderwolves, which are African rhino-sized, that can carry Space Wolves around.
