Modifying shop bought arrows

[NorthernRaider]

Got to thinking last night after watching Nemesis reprofiling arrowhead video on YT and then buiggering up one of these target arrows I have here.

They are the cheapest decent arrow costing about £15 for 6, Composite shafts, nylon fletching but soft round very iffy round headed target tips that are only about1mm thick. If you grind em to sharpen them the end falls off.

So I thought why not use the good bits shaft, fletchs and nock and cut off the crap target head and epoxy some decent steel field heads onto the shafts???

I cannot think of any major drawbacks can you?

So where can I get shome decent steel or brass decent pointy field arrow heads from that fit 1/4 inch 6.5mm shafts?
