410 reloads

[Eric Grims]

i am shooting a caesar guerini 410 over under at sporting clays (not a parker hope thats ok). At the end of last season I had a mix of shells in my bag and had some problems with the gun cycling from barrel to barrel. single trigger gun. I had Dan morgan look at it and he felt it was pretty much an issue of the 410 built on a 28 ga. frame and try shooting factory ammo. I only shot a few new AAHS loads afterward and it was good. I have to shoot more to be sure but my suspicion is that it was an older federal load i had around that was not hot enough to cycle. My reloads are winchester 296 powder 3/4 oz at 13,100 according to the book and I have shot a good many over the years in this gun with no problem. Not that i am going to risk any thing but was wondering if others are loading 296/AAHS or other powder and what works for them. I am a little nervous with high pressures of sub gage gun reloads but if I need a little more charge is that possible and safe in this hull?
thanks

Assume the Guerini has an inertia trigger? If so, you may have to lighten/smooth out the inertia block, or shoot hotter loads. I'd make the adjustment if it was my gun.

It does have an inertia trigger and if I need to I will have the work done. Would such a problem develop over time? I have used this gun for about 4 years without a problem.
Thanks

I suppose it's possible that some grunge has accumulated over time. I'd send it back to Guerini. I understand that their customer service is the best

I have used 296 in Win AA hulls for decades and never a problem in my Beretta BUT I had the trigger converted to a mechanical system vs inertia.
