humdinger-

Give the Remington AccuTip a whirl.

When it comes to vetting slugs, unless you get lucky, there is simply going to be a reasonable investment.
And worrying about the cost per boom isn't going to aid in your sanity. grin We purchase multiple powders and various bullets for rifle reloading and don't think much of it.
Buy a bunch of them, shoot them, find one that works and be done.

Once you find something that perks, buy an ample supply before they come out with a "new and improved" version.
