I am going to purchase a 243 win reamer from PTG. I dont want to turn necks. This will be used to chamber for bolt action rifles only for target and varmint shooting. I usually get 0 fb 1* 30 on all my reamers and throat with a separate 1* 30 throater. Suggestions for the other critical dimensions would be appreciated

Re: Help with spec on 243 reamer

What grain bullet will you be loading may be important? Twist of rifle?

I just bought a reamer made for the 115 Dtacs, probably a different reamer would be spec'd if you were only shooting 75 grainers.

Call or write Dave Kiff if you send him a few dummy rounds with your normal bullets seated he can cut the reamer to fit.

.275 is a min spec neck, be aware that lots of Winchester brass has a burr on the end of the neck that WON'T always work with this neck dimension- but the good brass will.
.060 FB will allow you to shoot most 105-107gr bullets and still pull off the varmint weight bullets as well in the same chamber

Re: Help with spec on 243 reamer

Gentlemen, thanks for the info. I am going with the .275" neck So another quick question. What is the downside to ordering 1* 30 - 0 freebore reamer and installing the throat with a separate 1* 30 throating reamer. This would give me more flexibility with a given reamer. I can think of a few issues but would like to hear what you guys think. TIA
