Which leads to what I think about lead points: I am not happy with them. I have screwed up more cartridges with lead-pointed bullets than I would care to think about. After I started reloading with the Nosler and Hornady plastic points, the problem was resolved. I know that not all bullets have Spitzer-type tips, but such companies as Sierra still continue to manufacture them---at least in many of the smaller calibers. That being the case, I would probably tend to use a DBM, since I would imagine that there would be less of a chance of banging up the bullet tips as might be the case when inserting and removing the cartridges from a hinged floor-plate type setup.
I realize that single shot rifles present a challenge when hunting coyotes. I would ideally like an AR in .243, but California has made it impossible to own one. So...next choice is a bolt action, although the Ruger Ranch Rifle in .223 is another choice. My experience is that once the animal is spooked by a missed shot, a second shot (even if from a semi-automatic rifle) is mostly worthless anyway, so I usually pick my shots carefully with the .22-250. trigger. The rifle was put together by Darrell Holland in 1996; uses a McMillan synthetic stock, blueprinted 40X receiver and Hart barrel. I had been using Nosler Ballistic Tips in 55 grain, but I don't think they penetrate enough to give me immediate kills. Probably due to poor shot placement; that's my fault.
I am experimenting with the newer Nosler Accubonds, but I haven't read much about this bullet, other than it appears to be kind of a hybrid between a Nosler Partition and a Ballistic Tip.
