Gunsmithing (newb) Advice on two 308 chamber options please

[mjpmattox]

Guys this is my first custom rifle so bear with me please.

308 cal broughton 1/10 RH twist @ finish length of 18.5"
roll my own using 168 and 175 grn SMK projectiles and RL-15
mostly target shooting @ 600 yards max due to max range availability in my local area.
AI mags which I do not know the max OAL length for as I have not received them yet to take the measurement.

My smith sent me an email asking which of these two chambers I would like if shooting a max of 175 grn projectiles.
1- 308 Bisley Match
2- 308 Palma Match

I tried looking into the "specs/Dimensions" but do not feel comfortable enough with my limited knowledge to make a solid decision. Please dumb your answers down for me as which one you would choose and "basically" why you made that decision would be great, as I would like to get him and answer before the weekend.

If i left out any pertinent details that would help aide in your answer please let me know, as I will try to answer to the best of my knowledge. I would really appreciate your help

Mike,
Call Dave Kiff at PTG. He will answer your questions. He makes the reamers and no one knows them better.

My Bisley reamer says 308 Palma Bisley Finisher. You need more info on which palma reamer he has.


Why isn't your smith telling you which reamer you need?


That being said just go bisley

Your handloading anyway so a "match" chamber isn't important. Just make certain that the chamber is cut straight with the bore and keep shooting until the barrel melts...
