I couldn't see a dedicated hello area so I'll do it here.
I'm a Brit (don't shoot me!) so unfortunately I can't bowhunt here, our FA Laws are a joke tbh.
I already own a TP GT Flex which I'm going to be shooting in 3D comps NFAS. I used to shoot an AFB, American Flatbow, that's what we call them here so we don't get confused with our English longbow.

I've been struggling to shoot it comfortably for many years due to a damaged left hand and wrist. I did ok taking a few medals but it was always quite painful.
I tried compound shooting left handed with a wrist release but that also hurt after a while due to nerve damage making my wrist sensitive.
Being a stubborn guy who hates being beaten I struggled on avoiding / ignoring the crossbow guys at shoots.
Anyhow, I eventually had enough of pain and thought ok lets try crossbow.
All I can say is WOW I've not had this much fun in years, seriously !
I've only had the GT Flex 8 weeks and I've been totally bitten by the Xbow bug.
The Flex is fine for comps cus we have to cock by hand and I can do 180lbs ok, no rope allowed, and it's plenty accurate.
I've been looking at guys on the net taking long range shots and thought I got to have a go at that, told you I'd been bitten.

I at first put a deposit on a Scorpyd Velocity 165 which a shop over here had due to a customer pulling out, he doesn't stock them normally. It was impulse really, I got to thinking and researching hard and eventually decided to cancel that idea and switch to a Excalibur Matrix 405.
I chose that over the 380 as it will be used for long range target only, (unless I get over the pond to try my hand at bowhunting one day,) so I've got that extra bit of velocity which will help.
That's why I'm here, to pick your collective brains, I hope you'll indulge this Brit!

It will be here tomorrow and I'm like a kid at Christmas, any tips when it arrives guy's?
I've been using ML6 silicon string wax on the GT Flex string which I had for the compound, and I've found that it likes dry PTFE lube sprayed on a rag and rubbed on the rail, makes it really slick and does not attract dust, would the same treatment be ok on the Matrix?
I can hit a round RH 9" Xbow unloader hanging from a tree limb consistently at 80 yrds, 100yrds not quite so consistent, standing offhand with the GT Flex which pushes a 385gr GT laser ii out at 295fps, I'm hoping to eventually push that range out to 300yrds bench rested with the Matrix. I've seen 275yrds done with a 380 so I guess it's possible.
Sorry for the long first post, I'm somewhat excited by the prospect!

Styks.
