Ihave a Rem 700 rebarrelled to 20 br. Even with the mag box blocked out at the rear, it doesn't come close to feeding. I'm just wondering if anyone has tried Wyatts br mag box replacement? Capacity is reduced to 2 in the mag but that wouldn't worry me, plus I could even try a floor plate extension that I've seen advertised.
