Arrow footing

[willyr1]

Hey fullas. Im shooting a 50lb falco legend. Its a nice bow but not overly fast so im playing around with heavy arrows. Im shooting gold tips and have been shooting 3555s at 425 grain but found that they are going only half way through goats here in New Zealand. The arrow head sticks out one side and fletchings out the other. So its a good kill shot but as the animal is doing its thing they tend to break my arrows and that's getting expensive. So I got some  5575s but have found they are so stiff that I need a 100  grain brass insert and 370 grain field point and 130 grain internal screw in weight giving me a 840 grain arrow. Im an engineer so I can make them but it seams thats a hell of a lot of weight out therethere. So im now thinking its probably a good idea to look at footing a 3555 arrow to get it up to 600 ish grain. Anyone have any ideas on weather I should look at internal or external footings or stick with a really heavy arrow? By the way my 425 grain 3555s are doing 145 fps and the 840 grain 5575 are going 123 fps. Any ideas would be great as there aren't that many trad shooter's in nz and im not really in contact with the few that are here.
Cheers.

Sorry that should of gone into the paw wow section. But still keen to here your views.

I would focus on a sharper edge on the broadhead. Sounds like you have enough weight and speed for a pass through (on the low end mind you as 165-175 would be ideal for that setup) so the only thing I can assume is the the edge is not as sharp as it should be.
