[QUOTE="Swamplord, post: 931568, member: 2460"] The Ammo Guide website has that load data for the 26 Nosler..... I am in the process of developing loads for my 6.5 Pro and have been searching out all load data I can find for the 6.5 STW and 6.5 Weatherby, max loads for these can be used as starting loads for the 26 Nosler and my 6.5 Pro .... the 6.5 WBY was used most effectively with the old H870, US 869 has a pretty similar burn rate might just be the go to powder for the 26 Noodler........ heres what Kirby experienced with Retumbo and his 6.5 Allen Mag, almost a decade ago.. ........ Re: 6.5 ultra mag ballistics? D-a, Yes it is very close to that but let me warn that I would highly recommend not going with the full length RUM case such as the 7mm, 300 or 375 which are longer then the 338 RUM case. YOu will be limited to using ball powders such as H-870, AA8700 and the very slow surplus powders such as 872. This is not a problem as they work very well btu you will have a powder bridging problem with a shoulder angle of this degree or sharper. That meaning when fired the powder charge will compress and wedge in the shoulder-neck junction of the case and cause soem severe pressure variations. I tested Retumbo and even H-50BMG in mine and experienced this problem. One shot would show no pressure signs at all while the next would blow the primer pocket. This is not a problem at all with the ultra slow ball powders listed so keep this in mind, will save you time and headaches down the road. Now my 270 Allen Mag did not have this problem due to the larger bore, still 8700 works extremely well in this. Other benefits of the ball powders is they burn much cooler then stock powders and are much less abrasive as they are forced through the throat of the rifle. A major consideration in case life when your burning +100 gr or powder in a 6.5mm bore. Good Shooting!!
