hello, i'm new to the world of reloading and have found the entire MO sight extreemly helpful... not only in reloading info but general info as well. that being said, i don't want to clog up the other forums with "remedial" questions.

i found a post talking about case capicity.

http://www.marlinowners.com/forums/index.php/topic,28447.0.html

i don't understand what the case capacity has to do with the loading under the loading guidelines??

for example i'm reloading 2 identical rounds using:

49 grains of imr 4198 (50 grains is the max load listed from the IMR website)
hornady 350 grain bullets
cci 200 large rifle primers


everything for loading 2 rounds is equal except for different cases being used. say one winchester and one remington. according to the above post/link, the win brass has 4.1 grains more capacity than rem brass. won't these load up exactly the same? won't there just be more empty space in the case for the brass with more capacity?

granted the load data i'm using specifies win brass. does the load data change if i'm using different brass? is this only relevant if when i get close to case capacity... ie. different bullet, or powder?

please help, because some of the warnings will scare the snot out of you. i don't want to go to the range with unanswered questions... second guessing all of my work/research/studying/question asking.

thanks in advance -wayne ???

Use your data but if you are using the smaller capacity case reduce the starting charge by that amount, the pressure will be higher but you will be safer and still get the same velocities with less powder.
i missed this part... so i can save on some powder by using the rem brass and achieving the same velocity? i'm asking to get a better understanding... not to save a few grains of powder here and there.

First, unless you use EXACTLY the items on the IMR/HODGEN website, dont use their dope.
Get the load for the bullet you are using. There has been problems substituting bullets/primers/cases.
thanks. i emailed my first loads to a guy i know who i trust about reloading. i started a minimum levels and went up 1gr at a time and stopped at least 1 gr before max. i sent him the screenshot from the imr website and he thought my loads were over max??? he quoted a few other reloading manuals and they indicated i was over max at my minimum charge??

is this site no good for working up loads?? http://data.hodgdon.com/main_menu.asp

You will get a more constant FPS & pressure fill your case with something. I use a veggie wad (becuase I have them for loading black powder) and pillow stuffing (dacron).
This way the powder stays next to the primer, and you get an even burn. If not the powder lays on the side of the case, and you get an uneven burn.
thanks for this also. i noticed with some of my lighter loads that i could hear the powder squishing (technical term) around in the case after loaded.

man this is alot of info to absorb!

thanks everyone for all of your feedback!

If it were me...I'd back that load down to at least 46 grains when using Remington brass.

Hodgdens load data is good...but when you start changing things around (brass) it goes downhill fast...Hodgden used Winchester brass for their data.

I messed around with Hodgdens load data using Remington brass too...with 405 grain bullets and H322...DO NOT USE 55 grains of H322 under a 405 in Remington brass...I'm assuming that 50 grains under a 350 in Rem brass is about the same thing (only worse...4198 is a much faster powder), its too much!

Using Hodgdens data with Remington brass...lower the charge by 4 grains and you should be OK.
is the IMR/Hodgden website data good is you're using winchester brass. so far i've created 3, 3 round loads using IMR 3031 and 3, 3 round loads using IMR 4198. i started at the minimum listed on the IMR/Hodgden website and went up 1 grain each time. i stayed below the minimum. and i used the same brass and primer listed in the IMR/Hodgden data.
