  1. 300 H&H OAL

    Hey guys, I'm reloading my 300 H&H and recently tried 200 grain speer, previously 180 grain interlocks and other 165-180s grainers. I dont have a speer manual but loaded them using data from another load book for speer 200gr but it didn't specify bullet type. At the published COAL I was way...

  2. Bullet Profiles

    Where, or how do you find bullet profiles measurements? The case head to rifling measurement, with a 140 grain Hornady ELD match bullet, is too long to make a cartridge that will fit my magazine and come close to the lands. It looks like I have three options for addressing the situation; 1.)...

  3. Loading Hornady 115 GN 9mm FMJ Round Nose Bullets

    I have a general question about cartridge overall length and seating depth for 115 GN 9mm FMJ cartridges. I've found commercial ammunition all over the place with regard to COAL. Winchester - 1.164 Remington - 1.107 Aguila - 1.112 Federal - 1.149 Blazer - 1.154 All my 9mm guns feed...

  4. 7x57 Lead SP Touching Rifling

    New reloader here with probably a simple question. Started reloading some 7x57 with Remingtons old 175gr RNSP bullets. Lyman 45th manual says to seat at 3.065 seating there causes the lead SP to engage the rifling (but not the jacket) making the bolt a little harder to close. This made me...

  5. 6.5 cm load too hot. what now?

    hi. i loaded what i thought was a ~min load for my 6.5 cm howa oryx. due to limited poweder options i was forced to.. research a bit to find a load that seemed to be correct for my powder. upon shooting, it seems it was not correct. Although the bang was arguably louder than usual, notbing...

  6. COAL

    I have tried every method to find touch. I keep coming back to the split neck method. I get the impression that if you have erosion the rifling doesn’t have sharp edges to mark the bullet. Split neck method: It seems that you may have to have an ideal neck tension to get good results? I plot...

    COL vs ogive

    Question? What happens when you load for jump is still longer than your book recommended COL? Several measurements to the ogive from lands is 2.313, I want to run some test loads at .030 off the lands (2.283), the COL at that measurement 2.923, 9th edition of Hornady and others say COL should be...

  8. COAL = Cartridge Overall Length

    Understanding what acronyms mean is important – especially in what we do. There appears to be a shifting meaning associated with COAL, either cartridge overall length or comparator overall length. Most all the time, the abbreviation COAL, means the length of a cartridge, given in inches, from...

  9. Case Length And OAL measurement

    Hey guys, This might be a dumb question but I haven't been able to find a good answer. I'm a long time gun enthusiasts but fairly new to making hand loads.. My question is how important is it to trim all your cases to the same length if you're seating your bullets based off the OAL...
