I am kinda new to the bow hunting thing, well two years plus a few years in the sixties. Heres the problem I have been using XX Advantage 2514 arrows. My son bought me a dozen much thinner,forgot the #, Advantage arrows for Xmass. I traded them in a Dicks for the closest match they had. Used a chart that I didden' t fully understand. My new arrows are XX 75 Advantage 2413.
I am set at 63 lbs. Hard cam I think.

Are the arrows safe ?
Will they shoot about the same? I generally can get a group in a 6" circle at 20 yards, have a little vision problem that makes the peep blurry. Yuch
How do I cut them? Thats what started this today a blizzard comming so I was going to set up the new arrows Once I cut them there is no chance of return so I wanted some advice first.
