Uni throater???

[Baron85]

Has anyone used a uni throater?

I have a new proof 223 barrel that I want to extend the throat to get better performance with the 75 and 88 eldms. Wondering if this is easy enough to do myself or if I’m better off sending to a gunsmith?

Yeah, I've used one I rented. It was very easy. Just go slow and make sure you measure well and you will be good.

Are there any other steps or tools needed or just ream it until you reach the length you want?

I will pull the barrel and mount in a barrel vice.

Do you use lube on the reamer or just dry?

Last? Where did you rent one?

I used oil or maybe wd40, then washed it out with brakeclean when checking it. I rented it from 4d reamer rental I think. It's made for doing it so it's pretty easy. There's a cutting reamer with a pilot then a stop that you can set per 1/1000". You know how far you are wanting to go I assume, so you can set the stop before that point then check it and go a bit more to get there and be done. It's pretty easy to do just be careful.

Good stuff. Me and a pal of mine soon to throat a couple barrels. JR1200W3 seems to know his shit with this.

Just make sure when u measure, u clean the the the throat perfect. Maybe use some break clean and compressed air to blow it out. Go slow and take your time. Try and get a bottle of thin cutting oil also.

Thanks guys. Saved me from taking it to the gunsmith for about the same price I will have the tool for the future.

Yes. But cost is there with tool and pilots. Freedom to do yourself, priceless!
