Re: Marlin 357

Another trip to the range to play with the 190 gr. cast and 15.5 gr. Lil Gun, however, stuff happened. As mentioned before, the barrel had been hand lapped. I hand lapped instead of firelapped to avoid eroding the throat. Nonetheless, the bullet nose now barely touches the rifling when a cartridge i...

BABore's Hardness Tester

BABore made a simple but accurate hardness tester. http://www.mountainmolds.com/pics/ba_bhn_1.jpg It's a spring loaded ram and a 3/8" ball that fit on a reloading press. The concept is not new, but this one is very well executed and easy to use. A flat point bullet or an ingot is set in place a...

Re: Marlin 357

I think I would use that keg of Lil Gun for a stool while your filling your cases with WW 296. I've only tried Lil Gun in my 480 Ruger SRH. Can't say I liked it. While accuracy was good, the pressure spiked real fast. Just a 0.2 gr increase went from no pressure to a fully flattened primer. With WW ...

Re: Marlin 357

OK, last time there appeared to be a error in the powder charge, so I loaded the 190 grainers with 15.4 and 15.6 gr. of Lil Gun and gave it another chance to show us what it's got. Since last time, the 2.5X Leopold has been replaced by a Williams 5D. The front sight is still in limbo while I experim...

does WW shatter ?

from the old forum: I have read elsewhere that if ww is heat treated that it will shatter. I was under the impression that it would not because the antimony was only about 4 percent. I thought this was only a problem with high antimony alloys and not alloy. So does it shatter when heat treated or n...

suggested twist

from the old forum: Could someone explain the effect of the twist rate calculation? If one were to make a bullet for a gun with a 1 in 16" twist, should the bullet be designed so that the suggested twist ends up as 1 in 16" or what? Thanks. As you can tell, I'm confused. ** So many people...

suggested twist

from the old forum: ** So many people get confused by the "suggested twist\ that I am tempted to delete it from the program. The "suggested twist" is my best guess at the ideal twist for a given bullet. If you were going to buy a custom barrel just for a particular bullet, you should...

Rooster Zambini vs. Rooster HVR

from the old forum, some formating issues with this post but it should be working in a few months: Since Rooster HVR lube has worked so well I was curious to try Rooster Zambini. HVR is recommended for rifles and Zambini is recommended for pistols. It seems to me that any lube that works well in ri...

Re: Marlin 357

Trying a 190 gr. in 1894 357 Since a 180 gr. hasn't done anything to crow about in this rifle, I thought a heavier bullet would be worth trying. It's not that I want or need more weight, but sometimes a longer bearing length helps accuracy. http://www.mountainmolds.com/pics/357_180_190.jpg I walked ...

Re: Marlin 357

When I slugged the barrel on my 450 Marlin, I used an egg fishing sinker instead of a slug. In case your not familiar with them, they're football shaped with a hole through the length. I have tried soft slugs and round balls, but found the egg sinkers were more user friendly. Only the middle of the ...
