Be careful with some of the LS load data being posted here. Way over max from what Hodgon and hornady list. Me I stick with 8.0-8.2 gr of longshot with 180gr hard cast or xtp’s.
Hodgdon 2021 lists :
Longshot 8.5 start - 9.5 max 180 gr jacketed , 34,600 psi
Longshot 7.0 start - 8.2 max 200gr jacketed , 35,000 psi
Hornady 10mm data has at times proven to be a shizzshow.
