Altitude affects sonic barrier, but has little bearing on SPL. Shooter's ear levels can be affected by temperature & humidity.dynotime wrote:How much does the weather play? I live close to sea level.

Is that what you have been seeing? I am looking for a Silence that will Reduce a 16 to 22" Rifle barrel as much as I can so I can shoot with out much noise leaving my property. And I like quite shooting.
Yes, within reason, length is better than diameter for a given volume & weight. There's a time component; suppressors have to do what they do between the time the bullet enters and when it exits. Longer cans simply provide more time.dynotime wrote:Will larger Diameter Silencer work better than smaller Diameter ones and will longer work better than shorter units. I am bench rest shooting so Sound reduction is number one.
I read that internal Volume is key. So Will a 8" long x 1.25" dia less noisy than a 6"x1"
As for greater volume, it depends on the design. Simply scaling up a design can have the opposite effect if there's not enough gas volume & pressure for the baffle features to do what they're designed to do. Any bigger than about 1"x7" on a .22 LR, the extra volume is best used for a post-core coaxial expansion chamber. I've done a couple recores that way for form 1 suppressors that were quite large.
Not anymore. Too much hassle & expense to maintain when one doesn't use it as a storefront. I just use FB nowdynotime wrote:Do you have a web site?

eForms for form 4 is not up & running yet. Paper only, and yes, ~8 months for individual, 10-12 for trusts. eForm 1 is running 2-3 weeks, government shutdowns notwithstanding.dynotime wrote:How long does it take to purchase one of your units? Can I use E-file? Times are shorter from what I hear.
