Has anyone developed a bullet model for naked and moly 115DTACs for QuickLoad? I have V.3.1 of the software and the heaviest 6mm bullet is the 107SMK.
QuickLoad bullet file for 115DTACs ???

Go to your Quickload\Data\Bullets directory and copy your Sierra.bul file. Paste this backup to c\temp.
Download a programmer's file editor such as the 32 bit version available on this page. Or use your own.

With this editor open the Sierra.bul file in Quickload\data\bullets directory. Insert a line after the 107smk and paste this line there:
".243, 115, Sierra HPBT MK ","115.0","1.295","4.65","6.17","4.83","","2",".243",".559",".559",".556",".551",".546",".000","2900","2800","2000","0","","25.0"
Save the file as Sierra.bul
Now when you open quicktarget pull up this bullet file, and select the 115smk.
I'd just give you the .bul file but there is no way for me to post that file extension.
There are not seperate enttries/selections for moly coated bullets in QL. To account for this you check 'Friction-Proofed' in the cartridge dimensions panel. This reduces shot start pressure.

Thanks, I will try that.
Is there any reason why I can't simply modify the entries in boxes for, say, the 107SMK, to change the weight, length etc? I tried it but for some reason it gives me very low MVs. Just looking for the easy way to Nirvana.

Mike, email me the updated .bul file,with the 115s).
I can upload it to my host and make it available here.
Please send file to: mailbox@6mmBR.com

I downloaded PFE and discovered it doesn't appear to work with Windows XP, only earlier versions such as 95, NT, 3.1x etc.
If you have time, you can e-mail the modified sierra.but file to me at:
ronott@sbcglobal.net
Thanks again.

That's what I did and I thought it gave me garbage out.
I found that I can modify the sierra.bul file by using Word. The data for the DTAC115 came up correctly, now I'm going to try some calculations. Let's see if I get the same garbage out,much lower MVs than I measure).

My load is 243Win:
* Lapua brass,54.6gr H2O volume)
* 115DTAC
* 43.0gr H4381SC
* 210M
* 2.860" COL
* 27" Schneider 5P barrel
This load gives 3,000fps MV through my Oehler 35P. The load came from George Gardner who told me it would give 3,000fps, and it did. QuickLoad estimates the MV at about 2,780fps and a low peak pressure.
One important thing: I am well into the lands with this round, as is George.
However, the primers are just a little flat and I thought I would try H4350, which I use in my T2K 6XC. I'm using QuickLoad to estimate the peak pressure and the MV,I want 2,960fps), but I am cautious because QL predicts such a low peak pressure for the H4831SC load that I know is hot.
I've got some loads made with H4350: 38.5, 39.0, 39.5, and 40.0 grains. I think these are safe, but I'll still be cautious tomorrow at the range.
I have not played with shot starting pressure. It seems to be a weak knob. The default value is 3,626psi, but taking it to over 10kpsi doesn't get me to 3,000psi and high peak pressure to flatten the primers.
Is there a good model for the 6XC round with H4350? Might be a better place to start.

I've run into this with a couple cartridges and powders. I had to edit the powder file to calibrate.
It doesn't feel right. But I haven't had problems since doing so. All other loads with the edited powder in the same barrel match.
But make sure you triple check everything first. Even trying another powder 1st. Just for a sanity check.

I've been testing the 115DTAC bullet file with as much real data as I can find, including different powders. One catch is that the bullets are seated well into the lands; this may make the ignition pressure jump to a very high, undetermined value.
I shot a few 243Win/115DTAC loads today using Hodgdon H4350, since I use it in my T2K/6XC, and measured the MVs with my Oehler 35P.
Afterwards, I tried to model the loads using QuickLoad, but got disappointing results that gave a low predicted MV,>100 fps low). Oddly, when I changed the powder file to IMR4350 I got a very good match to my chrono data using an initiation pressure of 6,000 psi,bullets are well into the lands).
Makes me wonder about the H4350 powder file data accuracy.

Three tips for Quickload.
1. When using a Hodgdon powder made by ADI, use the ADI equivalent,e.g. ADI 2208 for Varget), rather than the Hogdon data. I've found the ADI data is more reliable.
2. Be SURE you measure your case capacity. My 6BR cases have a full grain more than the default.
3. Yes, change start pressure value if you seat into the rifling. I recommend 5,000 - 6,000 psi. NOTE: this is quite a bit LESS than Quickload recommends, but it seems to work with match bullets.

I always use the measured case volumes, case lengths, and bullet lengths.
How do I find the ADI equilavent of various Hodgden powders? Thanks for the tip!
