[QUOTE="Pdvdh, post: 1115577, member: 4191"] I'm only shooting RL33 now in a 30/375 Ruger Improved. That cartridge has less case capacity than your .338 Edge. I load 87.7gr RL33. In that rifle I experienced a large reduction in ES when going from 0.007" jump to 0.010-0.012" jammed. I was jamming bullets 0.021" into the lands during barrel break-in and load development, because I was fireforming the cases to the wildcatted chamber dimensions. I needed the bullets jammed hard to hold the base of the cases in contact with my bolt face. I was also chronographing many of those loads. A consistent trend developed of low ES with jammed bullets. Your rifle may or may not act the same as mine did... Only one way to know...:) I have a .338 Edge but haven't loaded for it in quite some time. I'm in the process of building a .338 Lapua Rogue - a 338 Lapua Improved with a 37-degree shoulder. Got all the components, so will be sending action / barrel / brake to a gunsmith soon. I do intend to begin load development with RL33 in that rifle. Which is why I'm tagging along in this Thread. Here's a good thread that details load development, with a focus on how bullet seating depth affects ES with RL33: [url]http://www.longrangehunting.com/forums/f17/338-allen-xpress-rl33-load-development-120353/index18.html#post862519[/url] [/QUOTE]
