cbnutt,,, by the responses here,, you can see that there are a lot of variables involved. First,,, It sounds like your boss loaded some ammo,,, for you,,,, using published data from a manual. But,,, as an experienced reloader,,, I can say that each & every firearm is different, and published data is almost never "exact."
And,,, having someone else load your ammo,,, well,,,, most of us prefer to not do that. In fact,,, technically,,, if your boss loaded the ammo, & if you gave him any money,, even if just for the cost of the components,,, it could be classified as a commercial loading,,, by the ATF. A license is required to do that. (I know, I know,,, a lot of folks do it.)
Next,,, your desires to use the load for hunting deer. As a long time deer hunter with a handgun, I can say I agree with the above info about the variables involved here.
But,, in general,,, here are some things to consider.
A jacketed HP bullet isn't the best all around bullet choice.
Only your gun can determine what is accurate in it. That requires a lot of testing.
Accuracy first,,, as you have to hit the target before the bullet can do it's work.
In the 41 magnum,,, if jacketed bullets are used,, I'd suggest a reputable brand, in a flat soft nose design. Use factory ammo if you do not reload personally.
A better idea would be for you to get your boss to teach you how to reload yourself. In fact, you buy a manual,,, study it, and then select some components suggested by the manual as being accurate. If possible,,, buy 2-3 or more manuals. STUDY your caliber info. You will see a pattern of info on what they found to be accurate.
And if saving money to allow you to shoot more is why you wish to use reloads,,, then by all means,, learn to reload yourself. Let your boss be your mentor.
Lastly,,, I have found that in general,,,, in the 41, 44, 45 & most big bores like that, a well made, cast bullet,, pushed in the 1000-1200 fps velocity will take deer anywhere on this continent.
And you will get a lot more satisfaction if you do the loading yourself.
All I'll add is PRACTICE a lot & be willing to pass on a shot that you do not know you can make.
