Quietest centerfire round possible?

[ollie]

A 243 with 85gr hollow points and 11gr of trail boss.

The 22 ccm (cooper centerfire magnum) with a longer barrel would be awfully quite.

No contest the quietest unsuppressed fire arm I have had or even witnessed was a 16" 45acp.
Using 5.5 grains of unique and a 230 grain lrn lasercast bullet.
Even in a semi auto I believe it was as quite as my rim fire pistol WITH suppressor.
It was scary quiet ;D.

You'd be amazed at nonsuppressed 308 with Trailboss!!!

May I ask what loads you guys are using with the trailboss in .223 and .308?

I've had success with Sierra 125 & 150 grain SPT. Only tested to 75 yds.

I have a load for a 308 bolt rifle that is quieter than a 4 1/2 bbl. .22 pistol with standard ammo, and that is without a suppressor.

i still have to know.....why the desire to get, what will turn out to be very disappointing, results with aims of being quiet...and NOT just getting a suppressor???

The OP might want to load something quiet for various reasons with out purchasing a can. I'm deterred from adding another to the collection due to a reported 10+ month wait according to my Class 3 FFL dealer. What are the disappointing results that the OP should expect? I've shot some groups with subsonic ammo and no can that are more than acceptable to accustom a new shooter, not disturb people in a semi populated area, etc.

For my 223 loads i use 7.5grs. of trailboss with 45-55gr. bullet. its scary accurate from 0-50yrds.

My 25-20 is not that bad.
