So it looks like nobody has any actual hands on experience with it.

Looks like I might have to get a 300 instead...

I just got off the phone with SSK. I asked JD about some 302 data/info.

That didnt go well.

I even asked about buying data, I was not looking for a free-bee.

Oh well.

At least now I know where to not spend any of my $$$.

302 Whisper vs. 30BR
 

So what's the difference...or was the wheel reinvented?

From what I can tell through pics, its a 30BR throated long.

I explained to JD that I had the barrel, reamer and a throating reamer. I just wanted to get/buy some info.

He said "buy a complete gun from me and I will give you data."

Yep- he can be a jerk like that. He is short sighted and thinks he is protecting his product. He should be helping others as it would increase his business. I have spent more money shooting my rifle than the price of the rifle. Who cares that I did not buy the gun from him he should still want me to spend money but guess not.

30 BR load data.
 

Sierra edition 5 has 30 BR load data. Why not use that as a starting point?

Its all supersonic data that only goes up to 200 gn bullets.

This should give you an idea of what to expect with subsonics in a case similar to the 30BR:

Sierra 220gr/ 2400 10.2gr/ Win primer
Sierra 220gr/ 5744 11gr/ Win primer
Sierra 220gr/ 4759 11gr/ Win primer
Sierra 220gr/ Trail Boss 8.0gr/ CCI 200 primer

With a 150gr hunting bullet, you should be able to get 2600fps or better with H4198 powder.
