Re: Lubes & Crimps

The 25 to 40 whacks were after the 425 gr bullets were subjected to 4 recoil hits in the 475 cylinder which already slightly backed the bullets out. It took that many to move the case mouth past the bottom of the crimp groove. I think bullets backing out slightly might just be a fact of life with th...

Lubes & Crimps

I don't know if the longer cases helped accuracy. I can't shoot good enough with these wheelers to notice a difference. Years ago I tried using a scope to test accuracy, but under the heavy recoil it was always hard to keep the scope / mounts in place and after a hundred rounds or so the scope would...

Re: Bearing Length

You are right about the bullet not engaging till the front band, or even the full size band behind the crimp groove engages. The mold that you made me throws bullets with a .4" nose and a 80% meplat. When recovering these bullets, it is amazing to see how little of the nose is untouched by the lands...

Re: Bearing Length

I think your design program has a small glitch. I was working on a bullet for my 45-70 and noticed that the same weight bullet for the 458 bore had a longer bering length than for my .451 pistol bore. Then I noticed that the program must use a .451 bore diameter for figuring the bearing length for b...

Bearing Length

I had a Blackhawk in 45 Colt for years that I couldn't get to shoot very accurately. I measured the throats and they were between .448 and .450 so I had them taken out to .452 which helped a lot, but it still didn't shoot as accurately as I thought it should. I noticed that heavier bullets (325 gr) ...

Re: Rooster HVR problems?

Just a couple more things I noticed about Rooster Lube. My 454 has very tight chambers. .480" at the base and .479" at the case mouth. The chambers are .03" longer than my 454 cases then a 30 degree taper to the .4515" throats. A normal chamber has a 5 degree taper from the chamber to throat which a...

Changing Lubes

I have a Lyman 450 and a Lyman 4500 Luber/ Sizer that I use to lube my bullets. I am trying out different lubes and it is a real pain in the butt to change lubes. I know it would be easiest to have a dedicated luber/sizer for each lube and only have to clean out the die. The easiest method I have fo...

Re: Rooster HVR problems?

I have read about H110 shooting best at or near max loads also. The problem I have is what do they mean by max? Max pressure, Max powder compressed in availiable space or what?????? I don't have any way of measuring CUP or PSI and can only guess from looking at primers, case extraction, looking at p...

Re: Rooster HVR problems?

Sorry about the bad math/ typo on the 454 with Lyman Alox load! The 1st shot average should have been 1421 FPS and a 20 FPS higher than average velocity.
