I have never used the venture or had one in hand, but since discovering the kifaru gun bearer, that’s the way I like packing rifles(and my bow)
The universal should work fine for you, and if you’re right handed, left side carry would probably be best. I like my barrel isn’t hanging up in the brush, and it’s faster than a conventional sling to get your rifle ready, and that’s not an exaggeration
Some people don’t care for them because your barrel is in front of you, but I got used to it quickly
I have always hated traditional slings for various reasons, and I don’t like my rifle strapped to my pack and slow to access (and a lot of movement) they have a big bucket on the gun bearer so you aren’t trying to squeeze the stock in it, and it fits even the largest cams on bows… even the massive dual track prime cams
Not everyone’s favorite option, but it’s mine
