Tee Ritson put in a five-star performance, claiming a hat-trick of tries and goals, as the Raiders made it five straight wins in League 1.
The Raiders ran in 11 tries as they comprehensively defeated bottom-of-the-pile West Wales, who were outclassed throughout.
Coach Paul Crarey was forced to make several changes to his line-up, with Ritson moving to full-back in place of Luke Creswell, and it paid dividends as he revelled in the open spaces to pip several other contenders for the man of the match award.
Centre Declan Hulme ran him close with a hand in two tries before touching down himself. Mark Tyson moved into the stand-off role and also excelled, with Danny Morrow the pick of the forwards. Connor Terrill marked only his second first-team appearance with a try.
Overall it was a fine team performance for the Raiders, who cemented their position at the top of the table.
The clock was only ticking for three minutes when the visitors put their first points on the board when Morrow made a telling break in midfield before parting to Hulme who had Nathan Mossop on his shoulder and the hooker went in by the posts, Ryan Johnston adding the goal 0-6.
Barrow kept up the pressure and when Shane Toal was infringed in the tackle the ball moved wide from the tap penalty to Ritson who cut through to score 0-10.
The Welsh side settled down and applied pressure through a good drive from former Barrow player Joe Burke. This paved the way for Murphy to gather his own kick ahead which rebounded off a defender to score 4-10.
On the 20-minute mark Ewan Badham was sin-binned for a late tackle and in his 10-minute absence the Raiders ran in 18 unanswered points. From the tap penalty Mossop and Tyson combined for Terrill to go in from close range, Johnston adding the goal 4-16.
Ritson and Hulme then combined to send Morrow through a gap to score, Johnston obliging with the goal 4-22.
It was soon 4-28 when, following a dazzling crossfield run from Shane Toal, on hand to crash over was Ryan Duffy and on target with the goal was Johnston.
Wales were never in the hunt as the Raiders closed the first period when substitute Sam Dowsett, on for Mossop, parted to Tyson whose long pass found Hulme to cut back inside two defenders to touchdown, Johnston kicking conversion number five for 4-34.
The second half was barely under way when the scoreboard was ticking once more as Stack with a neat ball out of the backdoor enabled Toal to cross with ease 4-38.
Then a spectacular break from deep inside his own half saw Ritson pull clear but, with defenders moving in, his overhead pass found Tyson who scooted in from 20 yards, Ritson adding the goal 4-44.
Mossop returned in place of Dowsett and was soon over the line as he took a quick tap penalty and found players half asleep to race over for Ritson to convert 4-50.
Burke and Murray worked hard for the home side but another spectacular try came through Ritson, who was sent on a 60-yard run to the line from Tom Hopkins who made a neat break, with Ritson adding the goal 4-56.
On 68 minutes Dan Toal and Badham were sin-binned following a skirmish and Wales then went downfield and a high ball saw Murray out-jump Ritson to gather and dot the ball down, Ramsey converting 10-56. Ritson soon made amends when, following good work from Hopkins, the full-back completed his hat-trick to round off the scoring
