OK, with 200gr xtp's I started at 27grs w296 I have progressed to 29grs, I still cannot get the bolt to lock back on a empty mag. Accuracy is great, some old data that I have found shows 30-32grs of w296 to be OK for the AMP, the data is from Jurras/Nonte articles, the major manuf. load manuals show 27grs to be max.   So I want to make sure that 30-32grs is OK to go with. It's not like I don't trust the data I just want to make sure there are no editorial typos, and I don't want to damage the gun needlessly.

Thanks for the help

Go to Ian's AMY webiste, he has posted some reloading data from old Horandy and Sierra manuals.
For what it's worth, mine works fine in the range you are using : WW296 26-28 grs.
Good Luck

BIGBROWNDOG,
My Pasadena doesn't stop hiccupping until @ 30g-31g H110(296),Starline brass,200g XTP,CCI 350. Work up slowly, stiff-arm that bad boy and let her rip.

Good enuf, I ain't skeered. Just don't want to break my new toy.
I went back and looked at all the old original data I have and some of LEJ's pressure info, so I'll
Bump up to 29.5 and 30grs and let'er buck. Accuracy has been everything I've heard and read about.

On a side note, two of my mags have small cracks, does anyone repair them or are they trash??

Quite a few years ago I had one of my mags (original stainless) TIG welded I believe. If they are stainless they might be able to be repaired. I can't recall(CRS) at the moment who I had do the work, but they did a decent job without warping anything. I'll dig around in my stuff to see if I still have a receipt. I'll get back to you.

I'm finally getting back to you on your cracked magazines. I had my mag. repaired in 2003 by "Cylinder-Slide.com". The person I communicated with was Ralph. The charge for repairing one magazine (mine,floorplate broke off the body) was around $20.00 + shipping with a 2 week turnaround. I hope this helps you & whoever else might need repairs to 44amp. magazines.

The first step in loading for the AM is to differiniate between a gun malfunction and or a insufficient load. Takes some trial and error, no set rules. Headspace, proper lube , smooth feed ramp, are a few things to consider. FWIW

Well you sure said a mouthful  Lee,,,
 
That was the exact problem I had with my first AM.  It would not cycle reliably and I tried a bunch or loads (different bullets and powders and loads)  and got no where as I did not know the gun was actually broken.
 
The top "ear" was broken on the rear of the bolt and the piece was floating in the cocking piece and probably jamming the action.
 
Some lessons cost more than others,,,,
 
Heed LEJ's words of wisdom, he speaks volumes about such matters.  Not sure I agree with his guidance on adult beverages, but I'm willing to buy a couple bottles and discuss the matter during a "sampling" session.  Wink

Who was that masked man,,,
