Thread: .243 subsonic loads Tikka M55

So far I have tried the following: All with 414

Using Federal LR Primers and R&P Brass on its second trip around.

Sierra - 85gr HPBT with 43-44 gr
Hornady Vmax 75gr 40 - 42 gr
Sierra - 90gr TGK 42 - 43.5 gr casing had circular scuff at 43 gr so stopped there
Hornady 87 gr SP 40-43gr

I have worked up a few loads for seveal different rifles without too much difficulty but this one has been somewhat problematic.
