[QUOTE="Roughwater, post: 652640, member: 33915"] Hi, My hunting partner is on a budget and only has a Ruger 270 Winchester. I've been attempting to work up some 150 gn Elk loads for it. My goal is to get a 150 gn Matrix RBT bonded bullet flying as fast and accurately as possible within reason. Since the Matrix bullets are a bit pricy I have been using 150 gn Burger hunting VLD's for testing as I have some and they are cheaper. My first problem is that I'm not seeing near the published velocities on my Chrony. I'm talking at least a 100 FPS below what I'm seeing in published data. I actually thought my Chrony was reading low so a bought a second one of a different brand and it read essentually the same so that's not the problem. I soon plan to borrow my hunting partner's Ruger but right now I am testing my loads with a Remington Model 700, 24" barrel, 270 Win. Like other Remington's it has a really long throat so I'm thinking it might be reducing pressure and velocity? I also use a forster neck bushing die on most loads and size the neck down as little as necessary and wonder if that might also reduce pressure? I have mostly tried the slower burning powders, H4831SC, RL-19, IMR 7828, Magpro, and I have some IMR 4831, RL-25 and H1000 but haven't tried those last 3 powders yet. We did try Magpro in his rifle and it didn't seem to like it at all though it looked like it could be promising velocity wise. I did however get good accuracy and velocity with the Magpro in my 270 WSM with the Burgers and even better with the few Matrix bullets I shot. Any thoughts on the low velocity readings would be appreciated and maybe some suggestions on load work up for the powders I have on hand or any other would be useful. Thanks in advance.
