Being a recent convert, I don't have any experience with aluminum arrows.  My first recurve hunting bow I got a couple years back is a 53# Red Wing Hunter.  I tried it with my cheap CX Wolverine 6070s and after going up in point weight, I got it shooting perfect bare shaft.  I recently got a 42# BP Hunter and, having 10# less bow weight, I decided to try the same brand/model arrow in the 5060 spine.  Luckily I only bought three to try out.  I've gone all the way to a 190 gr point and they are still showing to be too stiff.  My question is what aluminum arrow size would equate to a 40-50 spine carbon as I think this spine carbon would be what I need.  The carbons I've found in that spine don't give the arrow weight I'm looking for.  

My other option is going heavier in point weight, but I don't want to buy a high dollar 250 gr broadhead.  I can get brass inserts but these arrows come with inserts already glued in.  Is there any way to get the inserts out, or will I have to cut a half inch or so off?  I'm not opposed to the heavier points and have some 190 Simmons interceptors already.  Just not sure how much trouble changing inserts on new arrows will be.

Thanks,
Matt Toms

Ive changed inserts before. Ive used a heat gun and boiling water. The heat gun was a breeze just keep direct heat away and heat slowly and keep checking insert until it comes out. But I think you would be better off with new arrows. I dont know your draw length but maybe some gt 1535 or 3555. Buy a test kit of arrows best investment for tuning.

You could try heat to soften the glue/epoxy to pull the inserts out.  Do you have a paint-stripper type heat gun?

I've had good luck with these arrows and they're inexpensive but I haven't found them in a lighter spine than 50-60.  The main problem is they come with the inserts preinstalled.  So to use heavier inserts, I will have to remove the factory inserts.  I have a way to heat them if I decide to go that route.  I like the 190 gr interceptors so I might try the inserts.  If I go with a lighter spine, I may not get them tuned with that much weight up front.

Thanks guys,
Matt

Call the folks you are getting the shafts from and they may just sell them to you without the inserts installed.

They came from Walmart so no chance of that.  Carbon Express doesn't even list them on their website.  The only place I've ever seen them is at Walmart.  They are the same shaft as the old Red Head Carbon Fury that Bass Pro used to sell.

You could get the inserts out buy taking out the nock and using a drill bit just smaller then the inside shaft and in a swift swing it should come out after a few swings. Be careful though when it comes out it could bounce around a bit

These are aluminum arrows? I remove inserts all the time. I screw in a field point so I have something to grab. I maintain a light steady pull with a pair of pliers while applying heat with a propane torch.

The moment the glue gets hot enough to let lose the insert comes out.
