CX300's and for GoldTips I'd go with 7595

For 100 grain fixed at your specs you'll need the 7595's on the Goldtips. And that's only 20 grains more or so. The 5575's will be slightly weak and you'd probably need to go down to an lower profile 85 grain head like the Slick trick 85 or the Montec HS 85 grain.
