information on Pinnacle Goex powder

[ole berthey]

I am new to the page here. I built a new rifle with a green mountain barrel on it in a 54 cal. I just tried it out the other day and have'nt got back to see if I can work this thing out or not. It is shooting bad, were talking all over the paper. I think it is in my patch. But here is my question, I am using Goex Pinnacle powder FFFg in this 54 I've never used this powder and was wanting to know what some of you think about Pinnacle.

You don't say if you are using a flint or percussion. Black powder substitutes ignite poorly in flint guns. I would suggest trying real BP like Goex or Swiss.

I'am sorry it is a percussion.

Before we can give you a reasonable answer, you need to retreve some of the patches and tell us what they look like.

New barrels often have sharp edges on the rifleing grooves and these can cut the patches.

Some of the new BP replica powders burn hotter than real BP and can burn thru the patch.

The patch lube can make a big difference in protecting the patch from this burn thru, so that is an important bit of information too.

If the patches are pre lubed, and are quite old (like they have hung on the desplay rack for years) they may be ready to fall apart from the breakdown of the material.

You didn't say what powder load, patch thickness and ball size you used. Any one of these can ruin a group if they are not correct for your barrel.

IMO, if the barrel is not cutting the patch, and you are useing a good ball patch size combination (like .530 ball and .015-.018 thick patch) with a good patch lube (like WonderLube or spit), and a reasonable powder load like 65-75 grains, you should be getting a fairly good group.
