I'm just trying to figure out exactly how copper throws cast bullets off. “Everyone” says copper fouling affects cast bullets in the accuracy department, I'm just trying to understand why.

So the copper damages the cast bullet?

What exactly is the effect that copper fouling does to lead bullets? I see a lot of posts on getting all the copper out of a rifle barrel before shooting lead, but I never did know how the copper...

The very few rifle tests that I've seen with bottle neck brass don't use anywhere near the max load of Trail Boss. In every test, accuracy fell off before they even got near the max load.

I used it in my K-98 with no problems. I've tried 11,12 and13grs with 198FMJs. Light powder puff loads. 12grs seem to be the best so far. And it may do better once I get this barrel clean. I've...

I don't know anything about cast bullets other than the store bought brands are cheap compared to FMJs. Those little rings of lube didn't impress me, so I put Lee Liquid Alox on 'em before I use...

I tried 10, 11 12, 13 and then jumped to 15 grains of Unique. And I load 10 rounds for each test. I then got some Trail Boss as I was running out of Unique. Several tests with all that and...

Oh I've shot 'em. Shot a bunch with different loads with Trail Boss and Unique. I can't keep them on an 11X8 inch piece of paper at 25 yards. The FMJs are easy to shoot. I bought 500. I have 400...

That's good to hear. I need to soften these bullets up. They are too hard.

OK then, 50-50, but I doubt if he has any tin. Neither of us has cast the first bullet. Looks like a try and cry project. Another friend went to his place and they just melted some lead and made...

So a 50-50 mix is right? I was thinking more of a 25% of pure lead added to the pot with my bullets. With Trail Boss, I doubt I'll get 1200fps out of the rifle bullets. And I'm thinking of going...

I bought these bullets from Hunter's Supply for a K-98 Mauser. They are .324 and are a 170gr bullet. My gun slugs .317/.323. I think they are too short, to hard and too small for my gun. My...

The reason I ask is, I bought some bullets that don't work. Too hard and too small for my application. A friend has a casting setup. It was left to him when his father passed away. But he hasn't...

Well, it's official. This gun does not like the .324 Hunter Cast bullets. We're talking shot gun patterns at 30 yards. I tried some 198gr FMJs. 12Grs of Trail Boss do nicely with those bullets. ...

It's official. These cast bullets aren't going to do good through this gun. You can see the results here:http://www.pixagogo.com/5724124248 It's the last three at the bottom. Click on a pic to...

I loaded 20 rounds with the 10gr load. I need trigger time also. Some seemed pretty weak. One was so weak that if I hadn't seen the mud fly, I would have pulled the bolt looking for a stuck...

I've been given advice all over the map on these bullets, but one guy said these rifles tend to have the throats shot out of them. That, coupled with the long jump to the lands means I need a bullet...

Well, I tried the 10gr loads at 33 yards. Better, but still wildly inaccurate. You can see the results here: http://www.pixagogo.com/5724124248 The last two went under the box. STILL no leading...

I'm going to try backing down to 10grs of powder. If the bullets are too small. Maybe they'll get a grip at the slower speed. Though if they are scooting down the barrel, the lack of leading...

Well, test results with 13gr of Unique was disappointing. I can't keep the bullets on a 11x8” sheet of paper at 29 yards. No consistency whatsoever. The last time I had this problem was with a...

I'm not for sure yet what's going on. I've only fired 10 rounds. The barrel has no pits and the rifling is sharp. I've loaded the next 20 bullets to just above the first lube groove. Just a...

With 14grs of Unique, absolutely no leading. That's the good part. The gun was shooting way left and scattering bullets the first 4 rounds, but seem to tighten up the more I shot it. But I only...

That's good to hear. I was worried I'd get leading from that long a jump. It's a flat base bullet. I was hoping Hunter's Supply knew what they were doing when they put the crimp groove where they...

They cycle through the magazine just fine. I'm thinking the fact that they're flat nosed is why they are so short. Like I said, if I barely stick a bullet in the case, they only measure 3.012. ...

I bought some cast bullets from Hunter's Supply for my 8MM Mauser. 170Grn flat points. If I seat to the crimp groove, the OAL is only 2.611. That seems awfully short. I've measured and weighed the...
