Really? At 1 meter, the noise affects the shooter. At 10 meters, the noise affects the shooter next door.
Did you read ALL the links on the first page I referenced? Evidently not. Here's the summary: http://guns.connect.fi/rs/summary.html
Here's the full report...
Distance is printed on the chart.
Blue = at the shooter's ear.
Yellow = @ 1 meter perpendicular to the bore.
Black = @ 10 meters perpendicular to the bore.
I did say it was more effective to do so. Still a 20 dB reduction in blast signature to the shooter when using supersonic ammo is plenty...
Rick,
Think again. From http://www.guns.connect.fi/rs/308measured.html
Downrange, most of the noise is from the bullet, not from the discharge of the firearm.
Oh yes. Firearm noise is measured on a logarithmithic scale, not a linear one. Every reduction in firing signature by 3dB means a...
Rick,
A suppressor works no matter if the velocity is subsonic or supersonic. However, with supersonic rifle ammo, the "boom" of the rifle is suppressed. The suspersonic "crack" of the bullet is not.
The directional noise diagram at http://www.guns.connect.fi/rs/dirdiagr.html shows the...
Oh, I've read the reports.
The M-16 rifle: The USMC seems to think the 5.56mm is sufficiently lethal. See http://www.elementconcepts.com/reference/USMCOIFDB.pdf , page 6. (NOTE: Link no longer works. The link was to a copy of the US Marine Corps Lessons Learned from OIF.)

I don't fully agree with this assessment.
Standard service rifle - Yes. Issued rifles are getting better. Some now sport free floated handguards, though triggers still suck, and sights don't have adjustments as fine as their match tuned brethern.
DMR versions of M16s or M4s - NO. US Army...
Your lack of participation in NRA 1000 yard highpower matches is evident. AR-15s and M16s have been successfully used for 1000 yard competition for many years. While doing so obviously places the shooter at a slight disadvantage (compared to a shooter using a cartridge and rifle giving better...
Building a bullet as a hollow point results in a better chance of getting the base properly squared. Remember, the base is the last part of the bullet to leave the barrel. And the last part to get affected by the remaining gas washing past. If the base or muzzle crown is not square, the...
BAH!
There are more 1000 yard prone shooters in the US than there are long range benchrest shooters in the entire world. There are more 1000 yard prone only ranges, and more 1000 yard prone only matches as well.
There is a competition forum on this board. Other boards (such as...
The latter statement is a bit misleading :grin: . From 1906 to around 1957, the 30-06 was the ONLY cartridge allowed to be used at the Nationals for shooting at distances of 600 yards and less. Between circa 1957 to sometime in the 1980s, rifles for 600 yards and less had to be chambered in...
Tim,
Does the local approving authority for your firearms certificate approve of magnum rifles? I understand that in some locales, they won't sign off if "magnum" is part of the cartridge name - even if it's a .22 magnum rimfire!
A .300 WSM and a .300 Winchester magnum are roughly equal in...
There is Shiloh Sharps, and there is C. Sharps ( http://www.csharpsarms.com/ ). Both put out good product. They'd better - the waiting list for product from either one is sometimes measured in years.
Reports from shooters that own rifles from either company are usually positive.
Marty,
I'd pick another spot in the basement. From a safety standpoint, high voltage/current electricity, and flames (pilot lights and burners, if you're using natural gas or propane) aren't a good mix with flammable or explosive reloading supplies.
Additionally, the air draft from the...
In order, it depends on accuracy and the price - and if both can be met while allowing the manufacturer to make a profit. Rumor has it that Federal Ammunition never made one cent off their match ammunition (grades 900A, 900B, 1000A, and 1000B), despite charging $4/box or more.
There is a...
Using existing .22LR chambers and barrels, this would be difficult. Why? Look at a .22 LR round sometime. Bullet diameter is the same as that of the casing. Actually, the .22 LR projectile is well optimized for best performance in the speed ranges it is typically fired at (900-1200 FPS). To...
RCBS has a pretty good step-by-step guide on their site. I don't do everything they say, but then again, some of the steps they list can be accomplished using other methods. (For example, I'm using a progressive press instead of a single stage.) Note that the guide is pretty heavily biased...
http://www.e-gunparts.com/forum/readit. ... 9417&cat=4 says it's a Savage/Stevens Model 87. I can't verify if this is true, but it does give you an avenue to explore.
Own more than one good reloading manual. A good manual has more than recipes, it also walks you through the reloading process, and may have specific discussions on loading for various types of activities.
Keep good notes. A reloader's logbook is invaluable. I've gotten away from keeping mine...
Imperial appears to be anhydrous lanolin. The latter may be purchased from any soap or candle making outfit, cost is about $8 for 1 lb. of it. 1 lb. is a LOT.
Many of the aerosol case lubes are liquid lanolin in some sort of carrier liquid. Dillon's case lube uses isopropyl alcohol. You can...
