PeteL Posted October 5, 2008 Report Share Posted October 5, 2008 Hi Tulkyuk, Assuming 24" barrel. QL gives : 3450 fps for 35 gn N140 at 50854 psi. 3505 fps for 35.5 gn N140 at 53138 psi 36 gn is over the top. This is the SAAMI designation, not CIP. If you require the calulation for a specific brass make, the water capacity and other data is required. There is no input for the primer type BTW, I'm no QL expert, only bought it at the Midland GF last month. Superb bit of kit. I'm using 40 gn WW 760 in my RWS Titan 22-250,24" match barrel, SAKO cases and getting 3540 fps, Extreme Spread 13, SD 6. All shots touching at 100 yds. Hope that is of use. The usual disclaimer applies. Peter PS I assume that by "Head" you mean bullet?. Oh, I see that Elwood has beaten me to it, anyway. Link to comment Share on other sites More sharing options...
