Funny that you bring this up. I just had this conversation with my buddy today. Everything above in reference to patterning your gun and the fact
that pretty much all factory loads will kill ducks at the proper range are all very true. However, my friend and I have been using different brands, noting the effects and sharing our result with each other. For the most part we have used whatever is on sale, mostly Winchesters mainly because they are on sale at Walmart and are very affordable. We both shoot the same gun, a Browning Gold with factory IC choke. 3" #2, 1 1/8 ounce loads or 1 1/4 ounce loads and we both like to try and kill our birds within 40 yards, but closer to 30-35 yards.
What we found is that Black Cloud patterns real nice with our guns and we have fewer cripples, it just seems to knock the birds dead and sometimes at a little longer range approximately 43-45 yards or so, but it is $22.00 a box. Kent shoots pretty good, patterns okay and gets the job done at an affordable $15.99 a box. However, we also experienced the same problems ejecting rounds on occasion as well a squib every once in a while. Heavy Metal is one of our favorites, but kind of expensive for us. We just bought some Heavy steel at Dick's the other night for $17.99 and are looking to give it a try this week. My daughter shot some in 20 gauge 3" #2 and made several clean kills at 30-35 yards. The Hypersonic loads well....are just that. They can reach out pretty far. We have had several ducks killed at around 70 yards which is a guesstimate based on using a range finder to mark where the dead bird landed as compared to where we could judge the distance was when the shot was made, but the are very expensive, $27.00 a box, they hurt my shoulder, and seem to be extra loud.
The Winchester loads get the job done at our preferred closer range, but as mentioned above we seem to have more cripples with those loads when we attempt to make the longer shots. At $12.00 - $14.00 a box they are affordable.
We are average shooters, shooting trap once a week with scores from around 18-21 on good days. Just to give you some type of idea of how we shoot.
I hope this conversation goes on as it will be interesting to see what other guys shoot...loads, chokes etc.
Regards,
Zane
