Today I’m shooting the Sig ProForce MCX Virtus AEG with heavier BBs than Sig recommends. You will be able to compare today’s groups with those from Part 3 to see which BB you think is best.
Before we begin I need to tell you about a discovery I made. In the last report the 0.20-gram BBs that Sig supplied with the gun were not feeding well from the magazine, nor were 0.25-gram Stealth BBs. In today’s first test I had the identical problem and discovered that it isn’t the BB; it’s the magazine. It does not like feeding the last four BBs when it’s in the semiautomatic mode. So, for all of today’s test I filled the mag with way more than the 10 shots I needed and after the target was finished I went full-auto outdoors in a safe direction with the BBs that remained. All four of the BBs I tested today fed perfectly that way.
