yes you can, but drop your charge and work back up, some rifles like jump, some don't, I'd set it .010 off the lands and try a 5 shot group, if your at 20, and .010 doesn't help, try .030 off, my 6.5 gibbs shoots best at .030 off, my 7mm Allen magnum likes them jammed .006.
your velocity may be a tad lower closer to the lands at the same pressure but it may be what your rifle prefers. hope this helps.
