I own a factory Sendero in 7,STW topped off with an elite 4200 6x24x40
im loadin Imr 7828 in it 150Bt at 82.5 ( if i recall there around 3500 but dont quote me on this one )and 100grn sierra hp and barnes x
maxed out at 88grains avg vel 3889 fps...
i have taken the 100grn tips to 90 grains of 7828 and have broken the 4000 mark but i blow primers out so i backed off a bit
I am still new to the long range game ,,and am still tinkerin with heavyer projectiles,,,
