From the accurate reloading forums- 6mm Ackley data from a Rem 700 with 25" barrel. 100 grain TBBC Reloder 19: 46 grains-2898 fps (they start here, although 46.4 grains is max @ stevespages.com) 52 grains-3424 fps (this is almost 6 grains over the max load @ stevespages) Reloder 22: 49 grains-3115 fps (they start here, although this is 2 grains over max @ stevespages) 53 grains-3397 fps (this is almost 6 grains over the max @ stevespages as well... Could anyone run these through quickload, and get some estimates on pressure? I don't want to get in an unsafe situation, never went over a book's (or knowledgable online source's) max. But, since I don't have a chronograph, maybe I am not taking near advantage of what my 6mm AI can do. Would 46 grains of RL 19 be too high to start with a 105 grain bullet?
