We were keen to see if premium shells really do give more bang for your (more) bucks, so we got some Gamebore Black Gold in several loads

These premium shells cost approximately 40% more than similar loads of more modestly priced ammo so we wanted to see what you get for your money with Black Gold from Gamebore who make impressive claims in their marketing material in respect of high velocities, superior technology and quality.

Chrono tests using a 28” Benelli M2 choked LM and shot measurements with an MTM digital reloader’s scale look like this:

Black Gold plastic wad 28g 7.5
Claimed velocity on manufacturer’s website – 1500
Measured velocity – Avg 1306 / Max 1335 / Min 1295 / Spread 40
Power Factor – Avg 555 / Max 567 / Min 550
Shot – 27.59g / Pellets 0.07-0.09g each

Black Gold fibre wad 30g 6
Claimed velocity on manufacturer’s website – 1475
Measured velocity – Avg 1229 / Max 1262 / Min 1199 / Spread 63
Power Factor – Avg 564 / Max 579 / Min 550
Shot – 29.79g / Pellets 0.11-0.15g each

Black Gold fibre wad 30g 5
Claimed velocity on manufacturer’s website – 1450
Measured velocity – Avg 1288 / Max 1327 / Min 1228 / Spread 99
Power Factor – Avg 605 / Max 623 / Min 577
Shot – 30.47g / Pellets 0.14-0.16g each

Black Gold fibre wad 32g 5
Claimed velocity on manufacturer’s website – 1450
Measured velocity – Avg 1279 / Max 1342 / Min 1213 / Spread 129
Power Factor – Avg 627 / Max 658 / Min 595
Shot – 31.83g / Pellets 0.16-0.20g each

 

 

 

 

 

 

 

Gamebore’s website uses the term  ‘Diamond Shot’ to describe the pellets in Black Gold and they certainly look shiny, quite different to normal lead shot however the variation in pellet size is no better or worse than much cheaper ammo and we were surprised to discover damaged projectiles in most of the cartridges we opened. Some pieces were half or less of the original sphere with completely flat sides and other overweight pellets were rugby ball shaped rather that spherical. These shot quality control issues would be of particular concern in matches with no-shoot clays where flyers outside the pattern make for penalty score risks.

We found all of these objects inside a single 30g/6 cartridge which was a surprise as we have not noted similar numbers of defective pellets in any of the much cheaper cartridges we have previously chronographed. All the Black Gold loads we opened during the test contained between 2 and 6 pieces like this except for the plastic wad 28g/7.5 which had more consistent pellets.

In summary – can we reccommend spending the extra cash on this premium branded ammo?

The marketing claims for Black Gold include very high velocities and superior components, like ‘Diamond Shot’ however our tests did not reflect these claims. The ammo we tested didn’t perform even close to the manufacturer’s claimed velocity figures and the variation from cartridge to cartridge within some loads was on the higher end of what we normally see in any ammo. The ‘Diamond Shot’ contained an unusually high number of misshapen pellets and was no more or less consistent in pellet weight than any other ammo we have tested.

In conclusion then, clever marketing and fancy packaging but an average speed cartridge with below average pellet shape consistency and no noticeable performance difference for 40% more cost.  No extra bang for your buck.  Which is disappointing because we really wanted to be announcing a great performance advantage available to the serious competitor, but in respect of that, we’re still looking! If you have any suggestions for exceptionally high performance ammo we would love to hear about it and will be happy to do tests for an article.

Finally if anyone from Gamebore wants to add a comment we will gladly publish it here.
