I've been struggling with this for a while...trying to make the descision on what to do with an XP-100 handgun in the safe. I "need" a super accurate long range (up to 500yds for hunting purposes) deer rig that will also double as an occassional bench gun for a local 100/300/500yd groundhog target match. But I would also like it to work on elk to...say...500 yds? I'm sticking w/ the 500yd range because that is the longest range I have available until I get a better rangefinder and can practice on some long powerlines. The struggle is...I'm trying to pick a cartridge that will do these hunting duties and be shootable for target w/o gulping huge amounts of powder and make practice expensive...and I LOVE to practice!!! Either way...the gun will be built w/ a 17" tube, HS stock, 3-12x32 Burris LER scope and all the accurizing goodies by Kirby. On one hand I'm thinking of building a 7mm WSM (1-9" Lilja for 175gr pills)...the radical possibility. It would certainlly do elk and deer to as far as I felt comfortable but gulp too much powder for a lot of quality practice. On the other hand I'm thinking .284 Winny set up to shoot 162gr Hornady's or AB's. It would work great on deer and the target line...but be a little light for elk?? This would be the "conservative" choice. I'd be more likely to shoot this more often due to the reduced powder appetite. I have a lot of "daily driver" specialty handguns (custom 7-08 Striker, custom 22-250 Striker, .222 Remmy XP, and .222 Remmy Mag Imp XP...and more Contenders that I care to count). These can handle about anything I care to do now but I'm looking to build that one special gun for really extending my capabilites and adding horsepower! The only additonal cost in having the gun built is opening up the bolt face. So...deal w/ burning more powder and build the dragster or stay somewhat conservative w/ the .284?? I'd REALY like a 500yd elk gun!! Suggestions??
