a question on Trail Boss in 45 LC

well after reading Hogdon's pdf on light loads using Trail Boss in any cartridge, I finally picked up a can and using the ratio they listed of 100% load density and starting at 70% I measured the case then weighed a charge...7.8 grains with the 255 Keith boolits I'm loading in my 25-5 for 100% load density....

Only problem is Hogdons website lists a max charge for the 45LC of 5.6 grains..

Just curious if anyone else has run into this and which set of Hogdon data to use? The formula the give or their actual load data....

Main reason is I already loaded up a few at 6 grains before I realized the discrepancy so then I loaded some test rounds starting at 4.8 to 5.6 My question is basically is there a problem with the 6 gr loads already done?

Which should a person follow, the 6 to 7.8 I had planned on from the formula or the data listed?

It's a good condition S&W 25-5, nice gun but not Ruger strength so......

Thanks in advance....

Use either one. Just don't compress the load as TB doesn't burn evenly when it's compressed.

Using the formula, you can't pack enough Trail Boss in ANY cartridge to exceed SAAMI safe pressures.

The stuff is amazing, especially using the formula when there is no actual load data published for a given bullet.

I've been having phenomenal success with both jacketed and cast bullets in both the 7.62X54R in the Mosin 91/30 and my 98K 8mm Mauser. Accuracy is right around MOA once you find the accuracy point. This will occur somewhere between their 75% and 100% points in the formula. You should be able to find an accuracy sweet spot for any given bullet appropriate to the caliber you are loading for. Have fun.

I kinda figured that but I like to ck. and Hogdon is closed on Fridays....I was hoping to try these and my newly roll crimped slugs tomorrow morning...sound like I can....

I mainly got the stuff for 30-06 subsonic with a 185 round nose I have for close range coyote control....damn things have eaten 1 too many of my hens....I like hearing that I'll find good accuracy with it....

but I was sitting there last night and those sized and primed empty LC cases were just calling my name...heh....

Trail Boss rocks. I use it with the 30-30 and 110 grain HP from Speer. Also use it with the 44 Magnum with around 7.6 grains, and a 240 grain LSWC.

Oh, btw thanks for the answer, trying to quit cigs and my manners aren't quite up to snuff at the moment.....

as long as i'm asking questions, I picked up the Sabot technologies nylon roll crimp tool after doing some reading on it and it does work great....however, the inner lip of the tool impacts on the slug before I get a good tight crimp and I have to dig a bit of a groove in the slug to get a good crimp....

Would it ruin the tool to take about a 32nd off of the inside lip? I think that would give me the clearance I need but I don't know if it would still do the job.....

Are you sure you did not read the 100% part for RIFLE cartridges?

Follow the load weights for straight wall pistol cartridges.

Well, the PDF says the formula works for pistol and rifle cartridges


It won't let me paste a quote but it says if it's not listed use the formula basically and as the bullet I want to use is not listed, I figured to use the formula...

It does say if you don't see your favorite cartridge, yet in the next line it states

"we have a formula for developing loads in all cartridges and it's simple to follow. This formula may be used in both rifle and pistol applications"

That's why I asked as it seems to contradict the load data
