.300 Whisper

[appleseed]

Last time I asked a question like this on the site, I ended up with a .20 vartarg project.

Tell me about the .300 whisper. Really like the .221fb case and low charge, LOW recoil required (due to injury), bullets from 125gr to 210gr. Looks to be accurate up to 300yds. Is it quiet?  1,125 ft/s is sub-sonic, however, there are loads for it that are faster. Why is this discussed as an attribute of the caliber?

My .243 is too much recoil. Maybe should stay with a .223 with heavy bullets instead, but a small charge .30 caliber is interesting!

Assume the .300 whisper is as long as the .223 oal due to bullet, so will the cartridge feed in the stock Savage mag?

This really depends on what you want the rifle for.  If you are wanting something to shoot through a can than the whisper is about the best you can get.  If you are looking for a low recoil paper puncher then the 223 is probably better since it doesn't drop as much at longer ranges.

I built a Savage to shoot the 7.62x25 Tokarev round. It uses a .308 bore which makes finding bullets easy. I would load it with heavy stuff at subsonic levels. The case capacity was about perfect once the long bullets were seated to a overall cartridge length of 1.75".

The biggest reason I did this rather than the whisper is cost. The dies are cheaper, brass can be bought rather than having to be made and you can fire surplus ammo in a pinch or buy over the counter ammo, both are reasonable compared to the whisper.

Here is the link to my built of the Tokarev rifle:
More on my 7.62 Tokarev rifle build (finally coming together)

Tons of load data in that link from my testing. No velocities but sound levels. I was able to get a load that had 357 mag energy levels the was as quiet as 22lr subsonics when fired from a 10/22. I have a video of the test if you are interested.

If you have any questions feel free to ask, I would be glad to help out.
