I went through some teething issues related to proper feeding on my Howa 308. Here's what remedied my situation:
1. Proper adjustment of action and action screw torquing (KRG Bravo).
2. Flaring the lips of the magazine.
3. Switched to a MDT magazine with the binder plate. My Accurate mag, didn't have a binder plate. My problem was in large part related to the tip of the bullet snagging under the feed ramp of the action. I reduced my COAL as a result, but this actually worked well as the rifle seems to like more jump with the 175 RDFs I've been shooting.
4. I wound up taking a carbide bit and relieving a small notch in the feed ramp in order to mitigate the aforementioned snagging issue. I followed up lightly polishing theVery easy to do and worked out great. The Howa is an inexpensive gun and I just went for it. I'd have much more hesitation doing this myself on a nicer action.
Hope this helps.
