Developing new loads...

[fenex]

Hi! I have some friends wanting me to develop loads for them. My problem is that I'm having some difficulty finding load data for some of the projectiles they are wanting to use. I am hoping someone may have a formula or mathematical equation that will help me extrapolate a means of figuring what powders and charges to use with which projectiles.

As an example, one friend likes shooting squirrel with his 17 caliber. He wants to use the Berger 25 gr match bullet to see how well it does. I've been by berger's website and am waiting to hear back from them on the load data. The only data I have at present is for the hornady 25 grain HP.

Is there a formula/equation which allows me to convert my data into something usable for the berger without blowing the gun up?

Here is the ballistic data I have on the berger and hornady bullets:

Berger: bc=0.147
Hornady: bc=0.187 SD=0.121


Any ideas would be appreciated. Thanks!

The best advice I can give you is get the QuickLoad / QuickTarget Ballistics Program. With these programs you can look at all the major powder and bullet manufactures combinations for all calibers or any wildcat case known. You also get to input your oal, case trim length and barrel length. It will come very close to giving you accurate psi & fps readings. I've been using it for in excess of six years. After you purchase the original program updates can be purchased at a reasonable cost as they become available. I reload for over 35 different rifles and 6 pistols in everything from 17 MachIV to 375 H&H. I would be lost without it.

An even better piece of advice is to let them assemble their loads on your equipment while you supervise. Loading ammunition for others is a no-win combination. If something happens to their guns shooting your ammunition, they will blame you even though it may not have been the fault of the ammunition. Don't load for others!!

hi! thanks for the replies thus far.

I will look over the quick-load and see if it is what i'm needing. Thank you for letting me know about it.

And I have considered letting them load their own, but some of these guys I have known for over 30 years and they know how I load,one, my cousin, has seen me shoot over 1000 rounds of my loads with no faults - he himself has shot over 500.) I have stressed and explained the processes I use to them, but to be blunt about it, they just want to be lazy. They have been informed that the ammo will not be held liable and I'm thinking about making them sign a release when I give them the ammo, just in case. So thanks for the advise, it is sound, but i think i'll probably have to take the chance for these boys.

keep the ideas coming! and thanks again!

fenex, The two best days of my loading career were when I got my brother-in-law interested in shooting, and then a year later when I helped him select all of his own reloading gear. Reloading on a single stage becomes a chore instead of relaxing activity with all the brass prep and reloading for multiple guns is heaped opon one person. Do yourself a favor and get them more involved in the process.

Good luck, Scout1
