"Mick-VA"My shroud extension arrived yesterday. Rapid delivery. The anodizing finish is very close match to OEM shroud. This gives me the extension I needed to place the 1/2 UNF just past the air cylinder. Now I have unlimited choices in LDCs for my Bobcat no matter the diameter and length. These adapters are impeccable in quality and construction and the finish is top notch.
I own the .30 version Bobcat pushing 83fpe with 50gr JSBs or Emperors and also an ER tuned 59.6 fpe .25 Bobcat. Both have quite the bark with the OEM 6 piece baffle system. Certainly on the wrong side of the edge of neighbor friendly. With a choice of Donny's excellent Sumo, Ronin, and Shogun LDCs at my disposal, I can shoot either gun comfortably without bothering the neighbors. I have neighbors to each side of me where the distance from my back door to theirs is just at 20 yards. However, there are no houses behind me for miles. I also had a volunteer test participant, a 7 point buck having a snack at 83 yards away. I shot past and over him with the .30 cal with Shogun to his left at my 98 yard target. He looked up towards the impact end but kept eating his salad with no concerns. Didn't even flinch.
Measurements taken with a class 1 proaudio mic placed 7 feet in front and rear at 45 degree off axis. Using C weighting and fast response to capture the full audio spectrum detectable by humans 20hz to 20khz and the quick transient spikes in sounds made by gunshots. All measurements are averages of 5 shots each front and rear. .30 cal Bobcat shooting 50 grain JSB just at 83fpe.
OEM 6 piece baffle stack system = 83 db at a sharp high pitched crack that will get your attention.
Naked no LDC = No way can't do it witout starting the lawn mower up. Prefer not to have the po po show up.
Huggett Regular size = 76 db
Huggett Magna = 74.5 db
Ronin = 73 db
Shogun = 72 db
Observations. The Huggett and the DonnyFL LDCs do a great job at sound attenuation and takes away the crack sound, higher frequency output that is so much more noticeable to humans. The Ronin had the lowest frequencies but a slightly higher db output than the Shogun. I'm guessing the larger diameter comes into play here? It was a good 3 octaves lower in frequency band than the OEM stackable LDC.
Also notable for me is that the more expensive LDCs do not necessarily outperform more economical ones. What a great concept - in this case you get more for less dough.
So bottom line. Donny's products are of very high quality. They are very effective and as a bonus, they are easy to disassemble for maintainence and cleaning. And oh yeah, they are a screaming bargain and are easy to purchase and quickly delivered. As a customer, I really can't ask for more ........well what's the next innovation maybe.
