Will the Sierra 250gr. open up better than the Lapua?
Alot will depend on what distance you are shooting at.
For closer range shots I found that the Scenar was less destructive and more dependable. For longer , plus 500 yard shots then would not hesitate to use the SMK.
Side note, not sure if you are aware , there is a recall on the firing pins of many earlier production TRGs, with yours being a 12 twist you may want to check it out. The new TRGS come 1 in 10 twist
