Ok so here's the deal... I've been playing in the 6.5 and 270 world for decades and I love them for sure but it's time for a little more energy at longer ranges. I recently was able to score an action I've been looking for since early last year and finally found one. I got a defiance anti-x XM length action and I'm trying to decide on what caliber to go with. The biggest problem I have is I am unable to reload as I absolutely do not have the time or equipment so I am limited to factory ammo or more preferable custom ammo such as copper creek, Pendleton, and the like. I would love to do a 7SS or 7SST but obviously that requires reloading and I cannot find anyone that does custom ammo in that caliber so I am leaning toward a 7WSM or 7SAUM (if I can find custom ammo). If those two calibers are not in the cards - what else would be able to deliver 1000ft/lbs at 1000Y+ with good accuracy? I have not excluded a 300WSM or 7STW but the ammo is absolutely the issue here. My goal is a fairly lightweight build that meets my requirements and obviously the caliber is the biggest decision. I am looking for suggestions and ideas with real data and factory/custom ammo suppliers. I am grateful for any info provided, thank you all in advance.
