Thanks to all who responded. I will go ahead, as I have experience with a good many pistol triggers. It does have the old style trigger, btw. I use a 2000 grit ceramic stone.
For those who wonder, with 41 gr Varget and 150 Sierra BT's, the rifle is capable of shooting one quarter inch three shot groups at 100. The first two shots can be in half that. The catch, of course, is that this is only possible with a really solid bench rest. The results offhand or even sitting are 2-3 inches, even with a bipod. I'd like a little better.
