| I've been reloading .45 acp and found a load that produces 1 3/8 inch groups @ 20yds... should I keep trying or just start pumping out this load? |
|
How much of a weather change are we talking here? I was hoping to pump some of these out for this weekend.
The load is 9.0gr of AA #5 with 200gr Hdy XTP.... The pistol is Springfield Armory XD45 Tactical. This load data is from the Lee Precision reloading book, I assume no responsiblity for use of this info. |

Hornady lists 7.7 start & 9.3 max with 800 to 950 fps respectively; AA lists 9.7 max @ 1050 fps; all using AA #5 from Load Data books. |

I've always used Lee, but now I wonder what book might have the best info. |

I've always used Lee, but now I wonder what book might have the best info. We see this alot with reloading. Different mins and maxs from different manufacturers. The reasons are myriad, to include different pressure barrels used, different "perceived liability" with different companies; some companies will purposely list a "low max" so folks don't blow up their guns.............etc. etc. Different lots of powder can yield different results also. This is why starting at min. load and gradually working up is always recommended, of course. As far as your question about weather: see how accurate that load is on a hot, dry day, vs. a cold, wet day. Variation couldn't be too much though, I woudn't think. I'd say go ahead and crank 'em out. |
| Thanks for the info. I've loaded alot for rifles but this is a first with pistol ammo. I've never noticed any change in group size with the change of weather, not to mention the 45's were shot using a rest which is not how I will normaly be shooting. Again, thanks for the info. |

Accurate Arms Manual #1 with Hornady 200XTP in a 5" 1911 45ACP using RP cases and
RP2 1/2 primers says : AA#5 ––-8.7––––924fps ––-9.7––––1050 It also lists 9.0 grains giving 951fps. Overall length as tested was 1.225" If the load is accurate as you stated and feeds reliably in your pistol I'd start cranking them out. |

I'm cutting you some slack cause your new, but we need a pic of your target. 
There is a saying on Arfcom, "pics or it never happened". http://i250.photobucket.com/albums/gg272/dryflash3/P1060042.jpg Note, if your reloads shoot that good, load a bunch.  This was only a three shot group, not nearly as impressive as above, but I'll try to get the pic up... |

Picture posting tutorial Link.
Keep trying, if I could figure it out, anyone can. |
