Thread: .243 subsonic loads Tikka M55

I use H414. Loaded it to 2.710 overall length to the ogive.

My howa liked 41.5 grains and a Federal Primer. S&B brass.

I was loading 95 grain targex. I have some flat base pro hunters for when I want to experiment.

What projectile are you reloading with?

I should be getting in theory around 2900 fps which is slow but it was accurate for me.

Not sure sub sonics would be easy. May have to pack the case with a case filler.

And finding a 6mm projectile which would expand may prove difficult
