I'm a noobie!! So I know these are probably dumb questions.

1) COL - How does changing the COL (seating the bullet deeper) change the pressure? I ask because I am reloading 44 magnum to use in a lever gun. My lever doesn't like the Hornady FTX (red tip) seated to the correct depth, it jams unless I seat the bullet deeper. Seating a Hornady XTP to the same depth feeds great. What should I do, I don't want to over pressurize my cases. Also is it safe to use the XTP (hollow point) bullets in a lever gun, don't want my a chain reaction?

2) How do I lube pistol brass? Dumb question .... I know. How do you do it. Why shouldn't the neck be lubed?

OK that is more than two questions but I would really appreciate any help.

Shortening c.o.l. will increase pressure, to what amount I can't say. For the load in question, what is the c.o.l. supposed to be?? How much deeper do you need to seat them to make them cycle?? What are some of the c.o.l. minimums listed in your reloading manual/data??

As long as you don't use pointed bullets in a tubular magazine, you will be okay AFAIK. Apparently you could have a chain fire in the tube mag with pointed bullets from them resting on the other cartridge's primers.

If you have carbide dies, you don't need to lube them. A little shot of the Lee lube mixed with rubbing alcohol will make sizing a touch easier, but not required.

You don't need to lube the inside of the neck for pistol rounds. (I think it pulls the shoulder forward on a cartridge with a shoulder!)

Just one guys opinion though, take it for what it's worth.

Visit Hornady's web site they have the COL for the reloads.

I can't find the info on the Hornady website, this is all I can find but doesn't list 44 magnum

Thanks for the info, I am using carbide dies so I will try sizing without lube. I was using the lee paste lube and lubing each case is a PITA!

My manual says 1.6" COL, my calipers are on there way. I sized the bullets to the top of the coneluer (sp?), the FTX (red tip) rounds don't feed, then without changing the seating depth of my dies I can seat the XTP HP rounds and they seat to the top of the coneleur and feed great.

Thanks for all the help so far!!!
 
I think that you are on exactly the right path. I loaded some XTP's and 1.6" came to the groove and look just like yours. The 2 different bullets are taking up exactly the same case capacity so the OAL should not really be the issue. It is the combustion chamber that you want to stay the correct volume.

The pointy ones are the same weight and like the leverlution bullets that are meant for lever guns correct? The hollow points will definately be ok in the levergun.
 
Seat the longer bullets deeper in the case to get them to feed. The COL is measured to the tip of the bullet. XTP HP have a flat tip and won't detonate in the magazine. Pressure is created when the bullet is jammed into the lands and the powder is still burning.
Bolt gun users will seat their bullets out further to reach the lands, reducing the jump space a bullet has until it engages the lands, making it more consistent.
They will also seat long bullets deeper to get the cartridge to fit the magazine.
Are the flex tip bullets hanging up as they are lifted from the magazine to get to the feed ramp? I suspect that is what is happening. Seat them deeper to just clear the feed ramp.
 
Shorter COL will increase pressures. Someone with "Quickload" software can check the parameters for you. Actually, for experimenting with things like this, Quickload software is probably worth the price.
 
pressure is direcly related to volume
volume multiplied by pressure is always constant
you can calculate the volume if the bullet is seated properly
then find the volume with the deaper seeting and you will get the change in pressure
 
I don't think Boyle's Law quite cuts it as a means for calculating peak gas pressures generated by a burning propellant in a confined space. Its valid for gas transfer calculations but this is somewhat different. I'd go for the software, as you can also use it to diddle with different powder options and bullets to arrive at a cartridge in a length you want along with the other characteristics you want.

Usually a bad idea to put pointy bullets in a tube fed lever gun. You dont want the points touching the primers of the next round in the tube. The plastic points may be too soft to cause trouble, but...

The "plastic points " in the picture are made specifically for lever guns.:kickInTheNuts:
