I have a Parker VHE 20ga and I had a Parker Repro 28ga. Both guns were choked skeet/modified. The 28ga was a disappointment on desert quail using 3/4 oz loads and the dog had to run down too many cripples. But the 20ga,also with a 3/4 oz handload of 7s, kills these tough little birds dead in the air with very few cripples. The 20 appeared to me to have a more effective pattern with these loads. The 20 is also effective with the modified barrel and these light loads to 45+ yds on them. The 20ga with 1oz loads performed extremely well on South Dakota Pheasant, and with the 3/4oz load extremely well on Hungarian Partridge in Idaho. My comparison over a couple seasons and a couple hundred birds ended my desire to hunt with the 28ga.
