Starting loads with smokeless (Read 11378 times)

	I've already asked this question of one of the members here on the forum, but I'm trying to gain as much information as I can. I'm curious as to how people come up with safe loads when shooting bullets of a weight not shown in reloading manuals. I know that many most of you have enough experience under your belts to make those decisions based on that experience. I, however, have never deviated from published data. I'm now in a situation where I'm trying bullets of heavier weights than shown in any of the 8 reloading manuals I own. I want to come up with a safe starting load........one that won't hurt my rifle, myself or others. So is there a way I can safely calculate a starting load I can then fine tune over my chrony?

	This calculator comes to mind; (You need to *Login* or *Register* to view media files and links) , hope it works for you but first read and compare has many loads as you can so that you don't make the big mistake of using too much powder in too little a case with too heavy a projectile.

If someone inadvertanly provided the wrong information based on assuming I think this is what he is looking for that is where the real danger lies. JLouis Whew, JLouis, you're right! C. Sharps 1885 Highwall, .38-55, 1:14 twist Green Mountain barrel. There are actually 3 bullets I'm looking at. I could get specific, but I'm not looking for suggested loads...........I'm wondering how you guys who shoot smokeless come up with safe loads.

Thanks, I'm familiar with this calculator. But in this case, I'm wondering about Unique powder........which this calculator doesn't cover.

	I'm sorry about the quality of the picture. If you can't read it, I'll be happy to give you there Unique loads. It from Lymans #2 Cast Bullet Manual, with my notations from loads even in match results. Most of the notations from the 1980's / early 90's These are all low pressure loads for your rifle so, as a gage, I'd reduce the Unique loads by .1 gr for every 10 gr of extra bullet weight. From there go by velocity and pistol primer, pressure signs. After you get in the area you need, if your leary of pistol primers, switch back to rifle. Frank

	Thanks, JLouis. I don't breech seat nor do I shoot competitively. It's just me and my cartridges on my range here on the property. I have a couple of starting loads recommended by the fellow who was kind enough to supply some sample bullets. But I've only one of the powders and the other he suggested doesn't seem to be available in our area. I shoot a lot of Unique, so thought I might look at that powder. I've contacted Alliant to see if they will give me a safe starting load.

Frank Thanks, Frank, but that doesn't get up to the 350 and 360 gr weight bullets I'm trying to load for. As I mentioned, I've 8 manuals...........many of them long out of print, so I've a good source of loads.......just not the ones I'm looking for.

	I have similar to Frank's manual in my Lyman books. But...... I just did a Google search using: "Unique powder in the .38-55" and found several sites that indicate what you can use. Read a bunch of 'em, take notes, and see what shakes out as a trend. If you are using a heavier bullet, the lighter weight ones should be sensible as starters by dropping to the mid-range of that data. Anyhow, just do the Google thing. Buying books is never a bad idea though.

	Chris, you didn't give the weight of your bullet in your above discription but, my .1 gr powder reduction for very 10 gr of bullet weight, should still be very safe. That would be 6.0 gr Unique for your 350 gr bullet. You could take it to 9.0 in .5 gr increament and I don't think there will be any pressure signs but, watch carefully. Frank

	Hate to expose my ignorance, Frank, but I'm not sure I understand what you mean. Are you saying that I can take a published load and subtract .1gr powder for ever 10 gr my bullet is over the weight of that published?

	Chris, with your 14 twist barrel, I would not expect your rifle will decently stabilize those 350-360 gr bullets and would not expect good accuracy with them. I suggest you limit yourself to try bullets up to say the Lyman 335 gr bullet. I expect a load of maybe 9-10 gr Unique may be about right in your highwall. beltfed/arnie

	I think that is one of the bullets I have.
