I have been doing a lot of reading and thinking on what I want out of this project and what I want to accomplish with it. My list keeps growing and then getting cut back to something manageable. I have Not slugged the bore, done a pound cast, or even cleaned the rifle back to shiny condition to work on fit. I have strictly been researching load data for powders such as bullseye, titegroup, unique, SR-4759, IMR 3031.
What I am wanting to accomplish.
1. A fun rifle project with an existing rifle I never shoot. It needs to be worked out. Rifle is a T/C Venture 30-06. I was never really impressed with it with jacketed loads, so it got pushed to the back of the safe, and I actually like the rifle so it becomes cast bullet rifle and that’s how it will love the rest of its and my life.
2. I want a low velocity load for plinking, and I also want a higher velocity load I can work with for game animals, whitetail to be specific.
3. Finding he most accurate bullet and load combination of several different bullets, to determine which one is the best and which ones I can live with.
Questions.
1. Let’s assume I have a slug and pound cast of the chamber and have a know throat and groove diameter, and bore diameter.
What have you seen to work best as an average, a place to start? .0005 over groove, .001,.002???
Just looking for a place to start.
2. What would be my velocity cap? In your opinion with My alloy at 15 BHN, assume it’s a COWW ish alloy, gas checked and powder coated, the alloy is not brittle although hard “ish” it deforms quite nicely and doesn’t break into pieces. Where would you say I could “safely without having to worry about leading be able to go with velocity. According to the books It appears to be topping out around 2400 FPS. I think I’ll be ok as long as I get the Fit right.
Bullets I’ll be working with are: SAECO 315, 311466, 311467, Lee 309-170, 311332, and 311-413, Arsenal 311-170RF and a couple more depending on how these work out. I don’t have very high hopes for the 332, but I’m going to try it and see.
I understand there are many more variable here, but I haven’t done that much cast bullet rifle shooting and truthfully probably have been more lucky than good with what I have done. PC makes up for a lot of shortcomings when you are new. It has to have because I’ve had pretty good success with my 45-70s and 300BLK. Just trying to get a baseline in my head to make sure what I’m thinking makes decent sense and I’m going in the right direction.
