"I have a mauser in6.5 with a bad crown.Im thinking of shortining it , mounting a scope ,a new trigger,and maybe a new stock. anyone have any experiance with these on larger preditors? Before it was damaged it was a great shooter.[/quote]"
I have been using the 6.5x55 (and the 6.5-06 or 6.5-280) on varmints for years. I currently have two sporters in 6.5x55. One is a scout with a Leupold 2X. It is in a fiberglass stock, has a Timney trigger, converted to cock on opening and has the bolt handle forged. The other is a new surpluss military barrel I installed on a SR Mexican M98 action. It also is in a sporter stock but has a 3x9 Tasco World Class on it. Both are capeable of sub MOA with Sierra 100 HPs, Sierra 120 SPs, Nosler BTs and Hornady 129 and 140 SPs. The Sierra 100 HP is the only Varmint weight bullet I've used so far that holds together past 3,000 fps because of the fast twist. I have not tried the light BTs though.
The 100 HPs at 3235 fps will do a number on most any varmint up through large coyotes. The Sierra 120s are deadly also at 2926 fps on any varmint and are my usual choice as the they are zeroed for 225 yards with the 200 yard zero of the 140 SP. For deer and larger I prefer the Hornady 140 SP at 2710 fps. For the larger "preditors" the 140 SP will work fine.
