Good to see a forum for the Whisper crowd. Gives me a group of people to learn from. :)
I'm on a cartridge search. This is a general purpose, lightweight deer carbine for woods work and the possible 300 yd clearcut shot, it will have a compact scope with 100-200-300 yd reticles. What I want is a good compromise between trajectory, power and muzzle blast. It doesn't have to be silent, just ultra effecient and mild to the ear. I was intrigued by the article "A Quieter Coyote Rifle" and I want something similar only for larger critters and enough power for longer range. I have internal and external ballistic software and I've modeled the 30BR with the 150 gr Scirocco which expands well at low velocity, and it had plenty of performance with a bore/case ratio of 12:1 IIRC. It should work fine but I'd like to hear about real world experience from shooters with the same ideas. I need to learn about fast burning powders and high BC, fast opening bullets, etc. .338 or .358 maybe? Cast bullets?
