357 180 Gr H110 questionable velocity

[Orendus]

Thanks for the additional posts and information. Seems like I'm on the right track, but its nice to hear responses from others with far more experience.

I did a little experimentation this morning to check on case capacity of the brass and bullet I'm using. Unfortunately my calipers took a crap so I cant give exact measurements but what I did was take a case and trim it down to where the base of the bullet I'm using sits inside the case. Then I filled with H110 and weighed how much powder would be a theoretical 100% load. My results were 15.8, 16, 16.2, 16.4 and 16 Gr.

So assuming 100% is 16 Gr capacity then a 13 Gr = 81.25%, 14 = 87.5%, 15 = 93.75% (Note that 15 Gr H110 would be over any published data I've seen and is only used theoretically to discuss capacity) I have seen internet loads up to 16 Gr for a 185 Gr cast bullet.

Everything I've loaded from 13 to 14 Gr goes BOOM and as mentioned I'm sure would do the trick regardless of exact velocity... next loading I'm gonna mess with crimping. Would/should case capacity effect performance (accuracy) or does being able to shake and hear powder like Palladan44 mentions not really mater?

Whats the max published load for a cast 180 Gr bullet and H110. The closest I found was Lyman 49th 170 Gr #2 alloy and 15 Gr H110

I run a coated 180 with 15 grains of h110. This isn't from a load book. It is accurate and safe in my Blackhawk and Rossi. It is a stout load that doesn't have pressure signs.

Neither THR nor I take responsibility for following non published data.

As others have asked, getting a good firm plus crimp?

Not the best pics with a phone...



At least you know when its time to back off a bit haha. I did notice that my handle on the press started to stick a little on the downward stroke the more crimp I put in. Anyway I got some loaded up with the middle crimp setting which is just under buckling the case.

Thanks for the input, looking forward to testing!

Bottom crimp is what I prefer. Middle would be if I was still having issues.
I've buckled a good number of cases
