I’m a newbie to this Forum, and wonder where to post my questions on largebore SUBSONIC deer-hunting rounds and bolt action, long barreled rifles to fire same.

Any directions would be most appreciated.

Also, where is RA Berry and Mr. John Bridger of Bridger Bullets?

It depends on your questions. If they're hunting-oriented, they may be answered better on one of the AR hunting forums.
If they're handloading questions, they may be answered better on the Reloading forum.

Ask, and we'll see.

RA Berry and John (his last name is not Bridger) are both frequent contributors to this forum, but those are not their screen names. They'll chime in if they want you to know their screen names.

Thanks, George:

I read the article “375 Weatherby†by R.A. Berry in which he got pretty impressive supersonic performance from the Bridger Walterhog 300 grain 1.52 bullet.

The bullet, being so long and lean, would appear to be a pretty aerodynamic round for subsonic hunting.

What would be the point for using a large case such as the .375 Webby for subsonic hunting? Or better yet what is the point and reason behind using a subsonic round?
Check out ssk industries, old J.D. Jones has a whole line of whisper cartridges in various sizes that will meet the criteria. I believe he's got them up to a .577 or .600 whisper, correct me if I'm wrong.
IMHO, unless you're in a area where suppressors are allowed or if you're just wanting a light recoiling/quieter cartridge, or even "training" loads (kinda like little swimmies in the big bore world), approaching a subsonic big bore is worthless unless you're shooting a round ball that's measured in pounds.

We do a lot of subsonic hunting over here, and My choise would be the .458 Socom. I would not go below .45, as the bullets have to little energy.

Thank you for the response, Bent.

I think that the above response, from the Metalsmith, is typical among American hunters.

We are not allowed to use supressors, without expensive taxes, but we are allowed long barrels.

Would you please point me to a WWW site where I could view some typical bullets which are used in your subsonic hunting? I’m not aware of the .458 Socom. The .375 Weatherby was chosen by me because I’m aware of a 300 grain bullet, the Bridger Walterhog which is 4.54 cm long,.and apparently quite aerodynamic.

$200 one time few per suppressor. Obviously, make sure it is legal in your state and legal to use for hunting. For example, they are legal to own in Georgia but not legal on a WMA. It would probably be legal on private property in Georgia but I didnt research that scenario. Save up and get you one, they are lots of fun!

Here is a cool graph showing the sound levels from a fully supressed .308 rifle. The powder loads were varied to produce velocities from very subsonic to very supersonic. As I recall from the article, removing the supressor would raise all sound levels by about 20dB.
