[QUOTE="Tidesloe, post: 777728, member: 47761"] I have actually tried IMR 4350 with 180 Accubonds. I did a round robin test with it, might be better at 200 gr. bullets. It shot well, but not as well as the VLD's at my start charge of 88 gr. Retumbo. I chose Retumbo for it's temp insensitive nature, and after reading that IMR powders tend to be more temp sensitive. I'm loading a hunting round. So, are you saying that accuracy may suffer at higher pressure loads? My start charge is plenty accurate. 3/4" 200 yd. group! I've never shot groups like that before. I'm new to LR, and I've spent the last 40 yrs looking for that type of accuracy in factory rifles, and factory ammo only to learn after all these years that it aint likely. At least for me it hasn't been. Now with custom rifles, and producing my own ammo, I clearly see its very possible. EVEN for me. Having not chrono'd anything yet, I know that the 88 gr load is not gonna have the velocity I'm looking for, and would like to find something at the upper end that does as well. Thats part of the puzzle that I need to be implementing. In the end I would give up some velocity for accuracy. I just bought a custom 7 STW, with load development and testing already done. I'll have that rifle next month. The load for it is using Vihtavouri N570, 180 gr. VLD's. I suspect that would work well for my RUM as well. I already have some on hand, just got it yesterday. Do you guy's have any experience with Viht 500 series powders? [/QUOTE]
