[QUOTE="swampratt, post: 3156975, member: 15054"] Looks really nice. Something you may want to try is NO crimp. Or very minimal crimp like just enough to iron out the flare. When I measure the crimp I do not go any more than .001" tighter than the area below the case mouth. I have also found NO crimp with powder coat holds very tight .. well if you have say .002" neck tension. It seems the powder coat I use almost acts like glue. Try this if you have an inertia puller or bullet puller. Load a greased lead bullet and do not crimp it and then pull said bullet from the case. Notice how much force it takes to remove it. Now do a powder coated bullet of the same diameter. Notice how much force it takes to remove it. I let mine set up for a day before pulling them. The powder coated bullet was very hard to get it to move. I use Harbor freight red and cook for 15-20 minutes. That may make a difference. I have found the NO or minimal crimp in 357 mag and my 30-30 to have better accuracy. Yea you can shoot many rounds of lead or powder coat bullets before you get a lot of barrel heat. Unless you are sending them 1800-2000 fps then you start seeing heat much quicker. My 30-06 with cast lead has a sweet spot with Red dot powder at 1400fps 11.5 gr. I have rang 18x18" steel plate at 500 yards with that load. Rainbow trajectory though. [/QUOTE]
