Whisper Pictures and Results

Looking to build up a whisper before too long. Who has one? What caliber, twist and bullets are your using and whats your accuracy?

Thanks

300-221 (300 whisper, 300 AAC Black, ...)
16" barrel threaded 5/8 x 24 with SWR Trident can (SUBSONIC ONLY)
chambering reamer that allows use of 5.56 brass without neck turning
gas port in pistol position - .086
JP adjustable gas block
Redding 300-221 die set
Sierra 220 Match King BTHP
8.5 grains Lil Gun
approx. 1000 fps
100 yard accuracy at or slightly below 1 moa (does not like clean cold bore)

If you want to fire super sonic loads then forget everything I wrote here. This set up is 100% for sub sonic. It would suck for super sonic.

I'm strictly interested in subsonic. What was the twist again?

Re: Whisper Pictures and Results

I have a .300 whisper on a Remington bolt action.
1:8 Shilen at 16.5 "
Using the 220SMK with 8.4g LilGun gives me 1035fps .
Average accuracy is .7" at 100yds for 5 shots. Ive shot smaller and larger groups dependent on temps.
I posted a pic of it somewhere on here. Search my posts. Found it for you.
