Thread: History of the .300 Whisper now known as the .300BLK.

I remember that article in New Zealand Guns & Hunting magazine and always wanted a JDJ whisper of some sort but the components where expensive and I was getting out of the bush more and out onto the tops doing more long range.
Now the last 4 years back into the bush stalking again with my trusty vizsla and 300BLK. Having a background into long range shooting and hunting has helped getting into the subsonic thing, consistent reloading, validating velocity and drops and using the right projectile for the job.
I’ve got 3 mates I reload for using the big heavy Rem 700 300BLK they are ok off the shelf rifle but too heavy and bulky for my liking and heard mixed results with the rugers. That’s way I went custom tikka 12” barrel short and light.

Having the 300 Whisper SAAMI speced to a 300aac Blackout, better subsonic projectiles, YouTube, easy brass cases to make has helped a lot in its popularity, time will tell how Hornady get on recreating the wheel and SAAMI specing the 338 Whisper to 8.6 Creedmoor.

Wingman,
is there any real difference between the 300 and the 338 in terminal performance?
208gr A-Max’s and 230gr Berger OMT, SMK 220g mostly penciled through requiring multiple shots, I’ve had the odd tumble in deer body shots but slow killing compared to The Lehigh’s are the quickest killers for body shots I’ve used so far. With the amount of shooting I do I don’t know if I can afford running a 338.?

Time to get my ass out of bed it’s my week off work and it’s time to kill some goats and get some venison for the cats I mean for the fridge.

Yes the .338 had much better range and the 300gr bullet is longer than the 240gr .300 whisper bullets meaning bigger knife like wounds. The red hind in the pic above was taken at a little over 200y.
All those bullets you listed are not suitable for subsonic hunting. The .300 whisper was designed around the longer 240gr SMK and the WC 250gr which tumble through bone and flesh much better than a shorter bullet that will pencil through.

Ive sbot plenty of goats with both the .300 and the .338 whispers and had mixed results from boiler room shots from dropped on the spot to continued eating for close to a minute before falling over. Regardless of cal with subs a head or neck shot gets it done faster. Treat a heart lung shot like an bow hunter would.
