6 northern ca pigs down in their own tracks with Barnes tsx or ttsx. 4 with 25-06, 2 with 35 Whelen. 2 Wy antelope down in their own tracks; 25-06 with ttsx. Barnes work. Was hard to get repeatable load tests with Hornady gmx because of extreme dimensional variance lot to lot. Recent load development using Hammer Hunter and Absolute Hunter has been very encouraging as to accuracy, velocity, and ballistic coefficient. Echo a previous comment.... monos in general are longer for equivalent leaded bullet weight so factory rifles in traditional calibers may not be twisted fast enough for heavy monos. Know your rifles twist and pay attention to the bullet makers recommendations. Since monos don't shed weight on impact, they penetrate deep for their weight so the appropriate bullet may seem light but would work just fine. For me, I'd start a new hunting load development with Hammers and would not likely need to look elsewhere.
