Using 240SMKs ==> 15.5 grains of 4198 = 1020 fps average (good) but Standard Deviation of 48fps (bad).

Trying 16 grains of 4198 and 17 grains 3031.

Then trying for accuracy at 100.

Just ordered some 240 grain SMKs to try. I'm thinking 15.5 grains should give me the starting point for the load.

Now what is the better muzzle velocity to head for? 1040 or 1050fps as average?

Do you have a 220 grain SMK load for the 30BR/302 Whisper you would be willing to share?

My supersonic loads - 125 <==> 185 are great but I continue to struggle with a subsonic load.

I'm currently working with the Lapua 200 grain Subsonic projectile and 110. Results at 50m are one hole but at 100m I'm getting vertical stringing.

Thinking about trying Trail Boss.
