Quick load testing

[Intheshop]

Will one of you QL users run something for me.And please correct any missing data...

22-250 case.Lee 55 (not bator) mould.22 grains of IMR 4895 ,Dacron filled,2.315 oal,medium crimp,federal primed.85 degrees temp.

Savage 110 with what I'd say is a tight chamber.Loads are "fitted" as close as I want to get.Meaning,perfect fit WRT how the nose snuggles up into the leade.Cases are fitted with all I can do,.0015" bump sized,zero run out.

In my reloading books,4895 isn't listed.I'm gonna shoot it over our chrono,but am interested in how ya'lls QL functions?

OK,what I got was 2475 fps...4 shots and not even running all the calcs,being as they were all basically within a few fps...

Just sayin,it takes effort to set up our chrono,and that is something that needs work...accuracy is what matters.I found a node at 2600 with above,using 4198.But felt acc could be improved....which does happen with 4895.

I am thinking about,going by seat of the pants,that I can hit another node with 4895 up closer to 2600-2700.Just curious what the QL data has,or figures on the matter?

Use starting jacketed data for same bullet weight. Dacron makes meaningful predictions impossible.

 

[Intheshop]

Ok,skip the filler...check.Does QL make any distinction for...#1,cast?

And #2,loads that aren't published data?Meaning,no 4895 data on above load?

Here's a little info on what it can do http://www.neconos.com/details3.htm

Here's a sample page. http://www.neconos.com/details3c.htm The shot initiation pressure can be altered for various bullet materials, jump, crimp, etc.

It will make useful predictions for a 350 gr bullet over h322 in a 45Colts .....
It was off by 25% for 4350 in a 6.8 on case capacity . It gave something like 19 gr as a 105% load and the case alone to the neck base is about 26 gr . So be smart about the data sometimes it's way off out in the weeds but the other 99.5% it's awfully close .
I want to get it but haven't yet .

Good advice. Just about the time you start to trust it it will burn you really bad, but it's surprisingly close with most things and will give you an idea of how various powders will react in situations where there is no published data at all and get you started on the right foot.
