cant decide on my next build, i have a nearly new remington 700 bdl chambered in 270 win. the problem is that it is exactly the same rifle as the older remington 700 bdl 270 that was passed on to me that belonged to my granddad. neither outshoots the other (3/4 in) with my same load even though there is a 25 yr gap between them. i wont alter my granddads rifle but i want to build another custom with the new one. i cant decide between 220 swift or 25-06 or 280 ackley improved. keep in mind, i have a 243,308,270,and a 7mag that i have spent alot of time to be great shooters. i will be overlapping as i have it pretty much covered but what would you guys suggest that i add to my collection? thank you in advance.
