Hello to all the long range hunters out there. This is my first post but I am a long time observer. I have a nice Rem 700 BDL Custom Deluxe in 270 Win that I will be upgrading. This will not be a complete custom build from scratch. (I have a different caliber in mind for that future project.) My application is medium to long range whitetail hunting - maximum 500 yards. On a good day under perfect conditions this rifle shoots 2" groups at 100 yards with factory 130 or 140 grain ammo. I figure that is better than average accuracy for an off the shelf rifle. I want to fine tune what I consider to be an exceptional factory rifle so that I can trust an ethical call when the longer shots present themselves. This particular rifle seems to be a good platform to start out with. I will be reloading my own ammo after I'm satisfied with the bullet delivery system... I already have an excellent scope. So far I've had a recoil pad installed on the factory walnut stock (which I prefer). I also replaced the horrible factory trigger with a Jewell varminter top safety trigger. I would like to hear from any of you out there that have also upgraded your model 700. My stock barrel has seen maybe 100 rounds but I would like to know who makes a really decent barrel - I am prepared to invest in a good one. Also would appreciate an informed opinion on optimal barrel length and contour. I do not care for the factory ISS (integrated security system) that my bolt was wearing Xmas morning and the lock time seems kinda "slow". Should I replace the entire bolt or maybe just get a new firing pin assembly? Would it be wise to bed the action now or after I get a new barrel? Please feel free to mention ANYTHING no matter how obvious that I should consider beyond the upgrades I have mentioned above. Thanks in advance.
