Lazzeroni Warbird Click Bang?

I have a Sako TRG-S from Lazzeroni in Warbird.I got it new about 8 years ago. Have always Handloaded. Using 165 gr. sst Hornady and RL 25 powder. On the Lazzeroni reloading charts it lists starting load as 93 gr. and max load 106 gr. When I first started out at 100 gr. I was noticing primer problems such as cratering and once a piece of brass got stuck in the chamber so as directions I backed down 10 percent and went to 90 gr. I have shot it all these years at this load but have always still had one problem. About 1 round in 20 does this. Usually I pull the trigger and its just a bang. but then there is the one that actually goes click bank. I actually here the firing pin hit befor the bang. Seems if the primer went off I would not hear the click. I have always used fresh Federal 215. If it was a delay in the powder going off I would think I would hear the primer poping but who knows. Any Help would be appreciated. Thanks

Look up the causes, cures, and dangers of "Hang Fire."

Re: Lazzeroni Warbird Click Bang?

That sounds like a very light charge! Ran the numbers in Quickload, and using 3.5" COAL and 90grs RL 25 it very low pressure (in the 40-45kpsi range). The click-bang is definitely a hangfire. I've run into them using a fairly light charge of slow powder in my 270-300rum, and the only solution is to increase the charge weight. I would suggest that you start working up the load over a chronograph. If your not really all that concerned about the velocity, then just work it up to a point at which the shot to shot variation is very small and leave it at that.

thanks so much guys. I didn't even know it was called a hangfire. I think I will increase my load a little at a time and see if I can get it to go away and then go from there. Thanks

Re: Lazzeroni Warbird Click Bang?

If you stuck a case, you were wise to drop your load but 10% on a case like this is to much. These cases use slow burning powder and these powders do not really like to be used at lower pressure. Generally 5% off max is about the right starting load.

I hate to say this but I believe alot of your problem is caused by the very light bullet your using. Yes, they have loading data for it but with a round as large as the Warbird, this size of chambering really starts to come into its own with 180 gr bullets and 200 gr are even better. THey just make the case work much more efficently and powder ignition is generally much better behind a heavy bullet because the weight of the bullet helps in building pressure for better ignition and burning of the powder.

Generally, your velocity spreads will also be tighter with the heavier bullets.

My brother has a Warbird and he tried to get the 180s to shoot. They did alright but never did really shoot well. Then he tried the 200 gr Accubond and the rifle really shot well, much more consistant then with the lighter bullets.

Just might be something to try.

Re: Lazzeroni Warbird Click Bang?

"Click-bang" is most commonly due to improper primer seating.

Big cases are best used with big - for caliber - bullets.

All powders are made to achieve best, most consistant burn rate when chamber pressures are near max in the cartridges they are designed for.

Re: Lazzeroni Warbird Click Bang?

Thanks everyone for help on both of the warbird threads. I saw another thread that said to polish the expander ball for smoother in and out. My expander ball had a small edge. I could feel it with my finger nail. I polished it off, trimmed my cases, went to 95 gr. for the occasional hang fire. Went to the range and shot around 30 rounds. All went well! Thanks Ed
