Thank you for your input,
I am waiting for the barrel maker right now, but did get an NOE HTC 400 mold and some powder coat to play with this spring.
I understand. This project has been on the back burner for a long time and I'm not getting any younger.
Based on the quickload numbers it should be about 9 lbs of free recoil. Not bad at all.

475AR and P Flados - I am simply amazed. The data you have provided is exactly what I needed. I was NOT expecting the level of detail you have provided. I have really learned something new in the...
Don't worry about drawing it. I have CAD. COL of 1.735 gives me some leeway. The Suppressor is an old Gemtech Blackslide I have had forever.
Muzzle pressure is actually the concern. I don't want to blow up a suppressor needlessly, it is an expensive and time consuming mistake. My pistol suppressor is the limiting factor, it is rated for...
After seeing your quickload chart I am specifically interested in chamber pressure. I am using a pistol suppressor and want to keep the pressure close to 45 acp. So I may need to back down on size...
Looks like I need to go ahead and get quickload to work out some of the finer details.
Good information. I am very familiar with a 1 in 38 twist. It is the factory twist in my rem 788 that I have been shooting for over 15 years. The real trick with subsonics is the need to be kept...
I actually had looked at your design in his catalog. Will be very interested to hear your results.
Thank you both for the input. I do have nanocad. The idea of a truncated cone might be the simplest. Running a few quick numbers puts it around 390 gr at 1" long made up of .75" base and a .25" cone....
I am looking for your input on designing a bullet for medium game (Deer in 100 to 200lb range) at short (less than 100 Yards) range.
Here are the basics.
1. Why? - Because. I have killed dozens...

5 Gallon bucket. A milkcrate with 1/4" hardware cloth in the bottom. Fill as many buckets as you can. Smelt at home later.

A couple of tings I have discovered. Used wooden spoons from the goodwill store for 25 to 50 cents are great for stirring. Also after fluxing I use tea light candles as a reductant. Helps to get the...

grady is good to go. Sent him a box of zincs and a few days later received back a box of ingots.

For smelting I use a 1 quart stainless steel saucepan as a ladle. $1.99 at goodwill.

Trailboss powder will be your friend in subsonic 308's Start about 11 grains and work down. Use as heavy a bullet as you can stabilize.

I picked up a dive belt this week at the thrift store. Formed lead weights on a nylon belt. About 12 lbs for $4.99. Scratched with my thumbnail. I haven't tested them for hardness yet, but for .50 a...
