RE: Sierra 90 Grain Game King.
I have a buddy that uses the the 90gr in his .25/06 Mt Rifle exclusivly. He has had really good results. The Sierra book shows a published volocity of 3400fps for that bullet, however, his rifle was clocked somewhere around 3180. He has killed somewhere around 20 deer with the 90 & most have dropped or fell within 10 yards. The largest deer he has shot was a 200lb deer he shot at a "less than idea" angle. It made it mabey 80-90yrds from the shot, but NO bloodtrail. The others have speew'd blood but when you hit 'em in the guts.....
I loaded some of the 90's this past year to shoot out of my latest purchase. A Rem Classic in 25/06. (I have been really impressed) They shot very well but I also had loaded some 117 gr game kings and started with those first. They worked so well (droped 6/6 deer shot with them) I never even tried the 90's.
If you TAKE & MAKE good shots I'm sure you will be pleased with the 90's. I plan to do some testing this year with 'em on deer. I know they will knock the heck out of a crow!!!
