Re: Have a little Problem
The one I currently have chambered is my 1000yd heavy gun, it has the shoulder pushed back quite a bit to get a .375" long neck, water capacity is 92.8gr. The 93.64gr for the cartridge drawing you show seems to me underestimated. I have not pushed the envelope on mine at all, my target velocity is below 2950 with 208 Amax bullets and it very easlily does that. According to Quickload I should be able to push the 208 and 210s to around 3200. I was surprised that Quickload nailed my starting loads so I would guess that it is close on the max loads. For 240 smk bullets QL shows over 2900 fps. The highest vel I have recorded with the 208s is 3020 with I think 80gr H1000.
The other reamer I have is closer to the one you posted. The gun I am chambering with that reamer will be a hunting rifle, whenever I get around to it. Both my reamers cut a .338 neck so necks have to be turned. My loaded rounds after turning measure .334. On the last lot of brass I got that is just where they clean up. The first brass I had wouldn't have needed turning if not for the chamber neck, they were very consistent.
