Help with data for a X5 legion.

[60crewman]

Picking up a legion today with a Romeo 1pro. Wanna shoot a steel match this weekend. I have N320 and some 124 blue bullets and some 124 berrys hollow base. Any quick suggestions as a good starting point. Thanks for any help.

Somewhere in the 4 to 4.5 range at normal lengths should work. You don't have to load long in the 320s.

 

If you don't have time to test before the match and need to make Minor, I would probably do the Blues with 4.3 or 4.4 at around 1.135"

Great thanks.

4.0 grains of n320 with 125gr blue bullets in my regular x5 got me 135,000 power factor. Haven't gotten to chrono with my legion yet. Sadly it was 20 something degrees today so chronoing isn't in my immediate future.

That sounds unnecessarily hot to me. 125 gr truncated cone Blue Bullets at 1.100" over 4.0 grains of N320 makes 131 PF for me out of a Walther P99 (4 inch barrel).  Unless SIG barrels are "slow," the longer barrel in the X5 legion would probably result in more like 3.8 or 3.9 grains getting the job done.

I'm a little late to the party.  But I run 3.9gr of Sport Pistol with Blue Bullets 125gr RN with an OAL of 1.135". My groups an phenomenal out of the X5 Legion.

Anyone have data for 147 FN?  I'm interested in your opinion / load data.  

 

Thanks!
