Need help figuring out a good non-lead load for 30-06
I've been having trouble figuring out a non-lead hunting load (mulies and pigs) and was hoping some of the more experienced guys and gals out there could give me some advice...
Using Hornady 165g GMX bullets, I've worked up loads with Varget and IMR 4320 (both from 47.5 to 51...
I would sort out the mixed cases and use all of the same brand for accuracy testing.
Remington & Winchester cases have different capacity, and the result will be different pressure with identical powder charges.
None of the trimming, and OAL measuring you have done, or different powder will make much differance with mixed case brands throwing you a curve ball.
rc...
Thanks rc. It hadn't occurred to me that it would make that much of a difference. Is it possible to say just how much of a difference it might make? For instance, if you have a good load that shoots 1" groups with uniform brass, how much could it open up with mixed brass that's been fire-formed and trimmed to the same length (assuming no military stuff).
I'd like to know if I...
I'm new to reloading and watching this post with great interest. But what strikes me as odd is your questioning if IMR 4350 is too slow. Seems to be commonly stated IRM 4350 consistantly performs very well for the 30-06 application in 165 and 180 gr.
Also, Nosler shows on their web site that the W760 as one of the 3 loadings they had luck with for the 180 grain and the ...
I guess I misspoke there. It's not necessarily too slow, but I found much better accuracy when I used Varget (and 4320 and W760) for 168g Noslers than 4350. IMR 4350 is absolutely awful for me in 150g bullets and the worst out of the four powders I've tried for the 168g Noslers. I suspect it's ideally suited for 180s with 165/168s being a gray area. Others may disagree, but ...

Seating depth is 0.01" off the rifling, though I haven't played around too much with seating depth.
That is way to close for unleaded bullets. Barnes has done much testing in this area and have printed articles on this subject. Try a test group of.030 and another .050 off the lands.... twice. Your rifle will like one or the ...
Runningman, I will give that a shot. The Hornady GMXs look just like the Barnes TTSX but they have 2 relief bands instead of 3. I checked out the Barnes website and found their rec for seating depths of 0.03 to 0.07, but I can't seem to find any articles. Can you point me to them?

Don't waste your time or money on unleaded bullets that do not have the circumferential relief grooves in them, they are a step backwards IMO. There is a reason Barnes went to circumferential relief grooves.
Try the 165 grain Barnes TSX bullet or the Barnes 168 grain TTSX bullet or the Barnes 150 TSX bullets.
Runner, you...

Snuffy, thanks for posting those pics! It's good to know they seem to expand uniformly.
I guess I never thought about stability and twist rate being an issue. (Apparently there's a lot of good points you fellas have made that I haven't considered...) However, I would think a company like Hornady would check, double check, and triple check, test, test, and re-test to make sure a...

Therefore they don't NEED those relief grooves.
snuffy, The name is runningman. Not only do I disagree with you but Hornady also seems to disagree with you! Because Hornady is also using pressures relief grooves on their GMX bullet. Those grooves cut down on unleaded bullets overly long bearing surface reducing pressure and smoothing out ...
I agree with you about the age of the equation. It certainly doesn't consider things like BC, or anything related to the shape of the bullet. That MUST have an appreciable effect on gyroscopic stability. Then again, I'm no physics major. The fact that the GMX is a solid does give me more confidence in a 150g bullet. To be frank, I'm really splitting hairs here. I was trying to go higher because I thought I could get more...
FDGB, I can't say I understand the greenhill formula either. After reading up on it, I come to understand it's historic significance, but also understand it's age. Meaning it was developed for CANNONS and they seldom used spire pointed boat tail projectiles. I think the GMX in 165 is purely a magnum bullet. It NEEDS extra twist to stabilize it, or extra velocity in a 1-10 twist. Most everybody knows that you can drop bullet...

Because Hornady is also using pressures relief grooves on their GMX bullet. Those grooves cut down on unleaded bullets overly long bearing surface reducing pressure and smoothing out pressure spikes.

It's interesting that this thread should appear because only a few weeks ago the laboratory I work for completed a contract for testing a series of what we called "green" bullets, in rifle barrels with different rates of twist. Our findings are the property of the firm for whom we did the work and of course I'm not allowed to divulge the details. (I assume the data will be published eventually however.) I can say...
