Magazine Question

I have a new Daystate magazine on my Wolverine R. Is there an easy way to reload a partially loaded magazine. When I try refilling the magazine most of the time I have pellets fall out. I have gotten in the habit of keeping my rifle with a loaded magazine, I shoot one leaving the magazine full but on a decocted empty chamber. Of coarse this doesn't happen when filling on a completely empty magazine. I opted for the new magazine because of the larger capacity. I hate to spent a hundred bucks to get another magazine. I actually went to order one the other day but when I saw 15 bucks for shipping. I just couldn’t do it.
 
I guess I Didn't explain very good. I am not looking to buy something else. I thought maybe just maybe I am being stupid. and there is way that when rotating the magazine to a empty hole the pellets dont fall out. If not I will probably buy the older style. I have one for my Huntsman but the locating pin is in not the same between the two. I never had a complaint with the old style. I thought a few more pellets would be nice so I ask if I could swap. Not AOA fault at all they actually went extra in letting me trade. I just didn't do my homework.
