300 wby update

That is correct sorry, I'm told 3/8". Freebore total, that's what I remember gunsmith told me the .0000 but I forgot it, I do remember the 3/8 though, I know it's not precise but I told to give me a rough measurement in inches

If you are ever curious to find out, Alex Wheeler has a YouTube video how to measure it. I use the Hornady tool. Might not be as precise as Alex's but it is good enough for me.

Finally got this 300 wby shooting great, 180 AB, 84 grain IMR 7828 CCI mag primers. I'm beyond pleased still going to play with the 165 and 168 Ab LR too, apparently 7828 is the shizzle!
