Anybody use a 300 win mag with the 220/230gr cutting edge bullets. Should i look at using something with a little more capacity like the 300 wby or the 300 rum. Has the shorter neck length on the win mag caused any problems when reloading these long bullets. I origanally wanted the rum but it seems there are very little rifles chambered in the caliber plus ammo and componets are very scarce. The win mag however is chambered in nearly every rifle out there and componets are easy to find and cheap. The wby of course is only chambered in wby rifles but i do like there rifles. Componets for the wby are not to scarce for the most part but they are definitely not cheap. So which of the 3 calibers would you recomend, looking to use as a up to 1300yd rifle. I like the laser line of bullets as they expand down to 1200fps which gives a lot of extra range/cushion to work with. Or should i skip all three and step up to a 338 lapua for these longer shots.
