I bought 2000 rounds of 142gr fmj FT bullets this month so I will be developing a load . Hoping to get around 1375 fps that's 808 joules and a TKO of 9.9 , and a Factor of 195. Bullet has a sectional density of .16
To give you guys a reference point I had a warm load with 125gr XTP's that we shot off the top of a mountain ... Was 1525 fps , 875 joules , 9.7 TKO , 191 Factor and 0.14 sectional density.
