This is a comparative testing and measurement of FPS for bruisemaster gold standard 7.1 bore 35cm barrel length, both using a combination of:
normal ausgel milky whites & public range yellow cheap balls
LDT milky whites specifically grown between 6.8 - 7.1mm
Originally had a LDT HK416 stock performing an average of 240-260 fps: [250 avg fps]
(high for stock, also had an 11.1v)
Then installed a 35cm alloy barrel just to test: avg FPS went up to [260 avg fps]
Then moved to the Bruisemaster 35cm gold barrel:
normal ausgel milky whites & public range yellow cheap balls: [270 avg fps]
LDT Milky whites specifically grown between 6.8-7.1mm: [280 avg fps]
LDT MW grown 6.8-7.1mm with LDT hop up: [270 avg fps]
Conclusion: I was highly impressed with the bruisemaster gold barrel, it basically improved my stock by 20 FPS.
Now the story behind my struggles and initial issues which everyone needs to know about to save you time and frustration.
Make sure the gold barrel is pushed right back into the HK416 t-piece. Get a torch out and small tooth pic and move the tooth pic where the inner of barrel is to where the balls move into the t-piece. If it depresses before the inner t-piece feeder then it isn’t in far enough. This can take considerable force.
(Didn’t have this issue with the J10 t-piece, however, needed to use glue to secure the j10 t-piece to gold barrel)
Balls, Balls and growing more and more balls.
Did I have issues doing this! Handling each individual ball x4 before getting it ready felt wrong to say the least.
I started trying to follow @bruisemaster guidelines but resulted in the balls being too small.
Moved to his 2nd method of just throwing the gells into heaps of water and timing it until they reached 6.9-7.0mm.
This is really important: It took me an exact time of 1.5 hours for LDT hardened milky whites to grow them to the correct size, growing the balls on a flat surface so they didn’t overgrow one another.
Before doing this method I was getting like 20fps and 70fps. Using the calipers verniers to measure thinking I was on the money but it wasn’t.
Realising i could use any standard ball grown to any standard size.
This helped me lose the frustration and worry of any ball overgrowing by .1-.3mm.
Also helped me realise that i can go to public matches and if i run out of my own balls i can still be outperforming most other blasters on the field even with stock yellow balls.
Built one of Low guidos ball filters, after trying to measure balls this way, filter/capture, and grow the smaller balls more, and dehydrate the larger balls - this turned into a never ending - constantly perfecting frustration game. I ended up not using it, after all those days of building and perfecting it.
Hope this info helps.
Love ya @Bruisemaster
