The guys at McClelland Gunshop can help you out with reaming your chamber. They do a good bit of work on "Africa" guns and have quite a few local DSC members as customers.. I am not sure they would rent you a reamer.. but I am certain they would do the work for you if you need someone to do it..
I typically rent from 4D Reamer Rentals:
https://4drentals.com/ they arent local to DFW, but they generally ship the next day and the reamers and gauges are in your mailbox in 3-4 days tops.. they give you plenty of time to get the job done (I think a week? I typically get it done in a couple of days when finish reaming a chamber.. its really just a matter of having time to get to it.. its only a few hours task once you get started)... and they are reasonably inexpensive... The reamers I have gotten from them have always been sharp and good quality..
Im on the north end of the DFW metroplex... if you're planning on doing DSC this year, feel free to swing by on the 5th.. we're having a little party/gathering at our house for
@Bos en Dal SAFARIS... more info here:

And don't miss the AH dinner on Friday night of DSC...
Both would be a great place to meet several members of AH as well as a number of DFW locals that are into hunting/africa/custom rifles/etc...
Welcome!
