This. Don’t focus on the GPI part of the arrow. Actually, if I were you, I’d lean toward looking for a lower GPI shaft in a 300 spine and do exactly what Grizz said, add the weight up front to get you to that 475-500 Mark..300 velocity xt with some brass inserts or gold tip 50 gr insert and then add gold tip weights to the exact weight you want or victory v-force.300 with a 100 gr brass insert....
Used to be a gold tip velocity person. Made great arrows for building foc, but about 3 years ago I had to batches that where not good. I went to Black Eagle. Never looked backGold tips are my favorite to build now,as I really like their weight system and I havent found a tougher arrow then a gold tip,they are neck and neck with carbon force radial weaves for toughness.
I have 3 batches of velocity xt's built in different weights,i think my favorites are the ones that are 460 gr with a 125 gr broadhead or 490 gr with a 150 gr broadhead.I never reuse my arrows,well rarely.I have put the one velocity xt through 3 bears and 4 whitetails the last few years and a tom last spring....they have done me well......I think there are lots of excellent options out there...but my preference is the mexican arrows....:darkbeer:.........Grizz
I also own and have owned different types of black eagles,I have a dz .300 outlaws built with 100 gr brass inserts.I think be arrows are decent,I had others and sold them.I like victory and gold tips over them myself.I think the victory v-force and gold tips are tougher but they are all good arrows to work with....Used to be a gold tip velocity person.

Good advice here! In fact, call Lancaster and request a catalog. They have most of the arrows available with all the insert options as well. I always keep my Lancaster catalog next to the toilet for research. LOL.Try a few different types/brands out from lancaster.I buy all my arrows from there,unless I see really good deals on amazon.I will be placing another order in the next few weeks for more arrows to build...it makes the warm summer evenings melt into autumn quicker....Grizz
