[QUOTE="Bob Beck, post: 666327, member: 41555"] Big bore, We are using a chamber design that is working extremely well in our EOL rifles. In the 300 it is long enough to give us a good case capacity to work with for several loads from the 185's up to the 230's. Also loaded cartridges fit and feed perfectly in our magazine boxes. We only use a polygon rifled bbl's made by Gary Schneider. These bbl's we have found through testing are a bit faster then many of the other bbl's made. Which is nice for squeezing a extra 25-50 fps out of some of the heavy bullets. We like to refer to the rifling as flats and grooves vs lands and grooves. This also helps with less throat wear, and less chamber pressure. Of course work up on your own load in your personal rifle with attention to pressure signs, but I am using H1000 at 91 grains in my 300 with the 230's at 2975 fps. [/QUOTE]
