Powder Density Question: H110 versus Alliant 410

Postby Redhead78 » Thu Feb 27, 2020 8:25 am

Well, I'm still trying to dial in my 410 bore TSS waterfowl load. My first attempt was to squeeze 270 grains (lightest payload my UCB will allow) of #9.5 TSS in a Fiocchi 2.5" hull using the TPS410 wad (trimmed) and 19gr of H110. There just isn't enough room to fit all that and allow for a good crimp. So, my next option is to try another powder. Several recipes are showing between 12-14 gr of Alliant 410 with acceptable pressure and performance. My question is can anyone estimate the volume difference between 19gr of H110 and 14gr of Alliant 410? What I'm trying to figure out before actually purchasing another bottle of powder is would switching to the fewer grains recipe of Alliant 410 save me any space inside the hull?

If not, then I'm afraid my only option is to resort to loading in 3" Fiocchi hulls and using a different press set up for such.

Thanks to everyone who has offered up their thoughts and insight. Much appreciated, this forum is a wealth of knowledge.

Disclaimer: If I end up modifying a published recipe to fit my needs I do plan to send them in for pressure testing before shooting. I posted this on another forum, but thought there might be someone that has run into this before and wanted to ask here as well. Cheers!

Can you just roll turn the first load ?

You could cut down 3" hulls to 2 5/8 or 2 3/4 to get the proper volume for your particular reload. I have a feeling if you went with 3" hulls, you'll have to fool around with spacers.

I have .32 caliber spacers and they are much easier to use than cutting down the wad/hull. I solved my volume problem by going with 3" hulls and found a Mec 600jr press set up for such. I had hoped to use my progressive 9000G, but such is life!

thanks for your help and suggestions.

Regards,

Anthony
