Hello Cheezwedge ,

As Dane said if you´re already used to chest load other spearguns, Rob Allen´s railguns are no different from those.

The only real issue in the loading pressure lies, (or at least what really defines it) on the length, diameter and number of bands to barrel lengh ratio, (specialy on bigger guns such as 130 and above, no matter what brand).
As a rule of thumb: the more powerfull the gun is the more pressure you will feel loading it.

Some people use a loading aid, specially spearos with small arms length and multiple band guns.
I have attached some pictures of a Rob Allen "loader", and of an easy way to keep it at hand while spearing. (Pic 1 and Pic 2).

As for the Vecta Reel it can be fitted easly in all Rob Allen spearguns.
I have attached some pictures of it too. (Pic 3 and Pic 4).

(sorry for the pics quality but their wore taken back at the shop 10 min ago a bit on a hurry...lol)

I hope it helped, best regards,

Dias
