I just added the tuning barrel to my HDP-50, and didn't plan to use the extension just because it makes the launcher awkward and goofy looking imo. However, I am curious if an extension that's not quite so long (maybe half the stock length or slightly shorter than) would yield gains somewhere between the 19 and 26 joules you measured. In other words, how proportional is power gain to extension length? Would be an interesting test. Keep up the good content. =)
another nice vid bud, .. I`m thinking of buying a chronograph myself but there are loads of different sorts at different prices on the market & yours seems a nice tidy device. I was wondering what brand/type it is and do you personally recommend it from your experience?
Thanks! I do like this chrono a lot. It's compact, 1 handed operation, portable and takes little to no storage. I really recommend it. Get the yellow button one if you can find it. Ir records higher than the red. Look on ebay for Xradar. That's where I got mine💥💥💥
