I need a carbon arrow primer

[Luckyned]

I'd like to give them a try but I have a few questions about them. I have a bunch of 5575's at 28" but they only weight 370grains and I'm afraid that would be way too light from my 50lb Montana longbow. Is there a way to add on the weight to get nearer to 500grains without warping the FOC factor of this setup? How about those tight fitting nocks on my dacron string? I was always taught I should use a loose fitting nock on my wooden bows. I almost hate the thought of trying carbon but I do love the almost-industructable quality.  Thanks ahead~ Ned

File the noc or use a string built for the noc size, as to the FOC, the old 15% doesn't apply to carbons.
 100 grain brass inserts and heavy points of 175 and up are the new norm.
