I took the liberty of sorting these JSB 50.15 grain pellets by weight in preparation of my FX Impact 30 caliber arrival tomorrow. Some are saying these are not as accurate as the 44.7 grain JSBs, but arrived first to the door. With my typical hunting range less than 100 yards, and more like 50 yards or less, these should do well.
After sorting these, I am not quite sure where the "Exact" comes into play. Maybe they meant in accuracy at the intended target?
I'll explain what's going on in the chart:
Starting in the "Master List" column, you can see the total weight spread for the four tins was 2.06 grains (48.28 to 50,34). The total count is 610 pellets, so they tossed in a couple of extras.
Looking at the "Left Row" column are the ones that fell below the primary weights of 49.xx grains, and are the 48.xx base weights with a total spread of 0.70 grains and a total count of 52.
In the "Main Sort" column are the primary 49.xx weights with a total spread of 0.98 grains (49.00 to 49.98), and with a total count of 538. You can see how those broke down in 0.20 grain increments in the "49.xx count" areas, and is how they are placed back in the tins.
The last "Right Row" column are the ones above 49,xx grains and are the 50.xx grain pellets. 20 total with a spread of 0.34 grains (50.00 to 50.34), also broken down in the 50.xx counts area into 0.20 increments.
I am fairly happy with these tins being mostly all in one base weight (49,xx), but are far short of the advertised 50.15 grain. There are only two that could be possibly be labeled at that specific weight. These are a lot better than what the MKIIs were, but only 4 tins compared verses 8 tins of those (see my previous posts).
I'll give them a whirl and see how well they do for my needs with the 700mm pellet liner. Worst case for me is that they will be melted down and recast for my .357 Slayer slugs I am already setup for.
