Powder Ignition Failure

[browningautorifle]

So, you're not going to try a magnum primer...lightish is still not a full load? Reduced loads in some cartridges will produce this very thing. Two ways to do it. Full house load and see or a magnum primer and see. Otherwise you've wasted time here... You never did tell us what bullet weight. The scales I set above show minimum 44 gr start. So you're under this set of loads by quite a bit...for the smallest bullet they show using this powder.

The bullets I am using are 196gn FMJBTs and when they go, they are accurate and shoot to the sights, but I agree that I could safely come up a couple of grains and see what happens. That said, I'm not sure adding a couple of grains to the charge will affect the chances of ignition, but you never know!

I'm not saying I will not use magnum primers, but the lack of neck tension seems a more obvious cause which I will pursue if the increased load does not do the trick!

I came on here to see if anyone else had seen similar symptoms! I am aware of the issues of high pressures/detonations with low charges of slow powder, but I had not heard of the particular symptoms I have reported. Can I just confirm that you have seen these symptoms before..?

Thank you for your advice and opinion, and no, I don't think I have wasted my time; I'm sorry if you think I have wasted yours!
