[QUOTE="Andrew Cowling, post: 1665371, member: 109547"] Good question. As a gunsmith and licenced manufacturer of amunition I have built and use a few 260 Remington. The 6.5-08 A square as it was originally called till Remington stole it was a great round. Unfortunate Remington killed it by selling the round in guns with short barrels and too slow twist rates. The 6.5 creedmore is just another case of someone trying to reinvent the wheel. It can do everything the 260 Remington can do but at much higher pressures. Since you have indicated that you will be hand loading Lapua make good quality brass. Also ammo availability is irrelevant in you case due to hand loading. Most load dater for the 260 is quite anemic. My personal experiences with this round is that loaded up it creams all over the 6.5 creedmore in velocity and down range distances. At a pinch and 243 winchester brass can be expanded up or 308 winchester brass can be sized down to make 260 remington. Just anneal the necks first. When I originally built mine Lapua wasn't making brass for the 260. Only had crappy Remington brass availiable. But I did have some new 308 winchester PMC match brass. I annealed the necks then run them through the full length sizer. Necks were then turned and insides reamed and trimmed. Primer pockets uniformed and flash holes debured. I am onto 7 loadings now with 1 necke turn and trim at 5 firings. Groups are amazing if I do my part fired from my custom Ruger VT action from a 28 inch 1-8 twist barrel made by Total Solutions Engineering here in Australia. 139 gr lapua scenar projectils leave the barrel at an average of 2800 fps. Average groups are 5 shot half inch at 300 metres. The chamber was cut with a custom reamer of my specifications made for me by manson reamers. So for me it is a 260 Remington all the way. 6.5 Creedmore is for guys who where man buns. Lol [/QUOTE]
