Re: Need recomendation for mould

Gas cutting at one location? Don't understand that. I run a 145 PB to 2100 fps , near MOA, AR & PC. Going to try a 150 PB in 308 for -2400.. That's impressive with that bullet speed - pretty well full load for 300BO. What alloy are you using? Hard? COWW? Yondering - assume you mean gas port cut...

Re: What type of the powder by the pound is best?

I've not used the Hi-Tek, but do use powder coating which I like a LOTS. I've been using Smoke's clear (just like the looks of lead bullets) and it's MUCH better (coats better with tumbling w/BB's) than is Harbor Freight Red PC.

PC'ing is easy to do, fast work works good.

Re: cast bullets in 300BO

OK, I took a while to think about this some before responding. First allow me to say "Thank You" to all who posted and made suggestions. I think I was not able to accurately describe what I meant by a "custom neck sizing die". It is actually less than crimping die as far as stres...

Re: cast bullets in 300BO

In all politeness, maybe I ask the difference in "neck sizing" by .003" and crimping a loaded round? Much less stress/pressure is placed on cartridge with a .003" neck size than a fully crimp. Oh, wait, now I understand your comment, it was when I ran the 8 rounds thru the sizer ...

cast bullets in 300BO

Hello all. I've been shooting the 300BO a bit, testing loads, etc. I have a couple of questions here. With groove diameter slugging at .308, the cast bullet needs to be .310". If the brass neck thickness is .012" that's just right on the max of .334" for chambering. Some of my brass w...

Re: 300BO shooting

Some gas tubes do have a bit of a bulge on the end at BCG, but some don't have the bulge. The pistol gas tube I ordered was just smooth on the BCG end. As I said, after the new gas tube was delivered I was able to compare the two - both as exactly the same on BCG end. The end at gas block would be h...

Re: 300BO shooting

You cut the gas tube? Yes - cut, de-burred inside, beveled outside, bent to required offset with 3/16" tubing benders. Laying side by side it was hard to tell difference from the new pistol gas tube that was delivered next day. Is this not a usual thing to do? Pretty sure I put the cut tube in...

Re: 300BO shooting

The lower fps load will have more muzzle blast? Thus more noise would be "perceived" by the shooter and folks standing behind the shooter? I guess that makes sense because as I see in QL there is a good bit more unburnt powder out the end of barrel, and I expect the unburnt powder burns ou...

Re: 300BO shooting

Thanks for the response - you've provided a couple of points I was interested in. The 7,000 psi at the gas port is good info. All fps and chamber pressure are calculated from QL - I was not using the exact bullet because QL doesn't seem to have Ideal molds listed, so had to scroll thru all the mold ...
