I picked up a dozen shafts to build my hunting arrows and was wondering what the best way to add weight. I'd like a finished weight of at least 450 gr, and at this point with the 125gr slick tricks I'm coming out ~425. I figured I'd just go with brass inserts but was wondering if I'm missing something?

I got in a practice session last night at dusk. Sure is a challenge when you have trouble making out your aiming point on the target. Shot the last group at 40 yds and was pretty happy to have three in about a 4" circle, but one flyer opening it up to paper plate size group.
