[QUOTE="Roughwater, post: 653037, member: 33915"] Thanks Lefty. I had just come from out back shooting off my 5 test rounds for velocity when I got your post and I had some cases already prepped so I made a 6th test load using your load data and went back out and shot it also. (I live in the country). Here are the results from my test using a ProChrono at about 12 ft from the muzzle: [COLOR=red]1. 55 gn RL-19= 2656, 2. 59gn H1000=2677, 3. 51.6 Gn IMR 4350= 2640,[/COLOR] [COLOR=red][/COLOR] [COLOR=red]4. 53 Gn IMR-4831=2640, 5. 61.5 gn Magpro=2824, [/COLOR] [COLOR=red][/COLOR] [COLOR=red]6. 56.5 gn IMR 7828= 2688[/COLOR] WLR primers used for all except WLRM used with 7828 and Magpro. All cases were once fired Norma cases neck sized with Forster bushing die. The rifle used for test was Remington 700 270 winchester, with 24" barrel. All the published data I have say's these loads should fly about 100 plus FPS faster than they do? I have checked the chrony agains a new Shooting Chrony and get pretty much the same results. Any thoughts anyone as to why the velocity discrepancy?? [/QUOTE]
