Evenings Guys.

Would someone with Quickload be willing to run some basic data for me?

338 win mag
S365 lot 74
Murom LRM primers
Winchester Cases
69,5 grains powder
Oal 64mm
250 grain Claw SP
24 inch barrel.

I just want a guideline as to whats happening with regard to velocity and pressure.

Much appreciated.

Steve.

Just using the Somchem data it predicts that with a 250gr bullet (QL does not have Claw in its database) you are possibly going to exceed max pressure. Lot 74 is hotter than normal and that will push up pressures even more. I would suggest starting 10% lower = 62gr to begin with.

Thanks for the quick response.

I've been shooting this load for the last year. Probably 250 rounds downrange. No visible signs if pressure but was curious as to what quickload had to say.

Thanks again.
