A friend hunts pheasants and rabbits with a 28 ga. over/under. He shoots factory Winchester AA 28 ga. with an ounce of 6's. At a little over 75 cents a copy, we've never cut one open to see what's inside.
I have had no luck finding a 28 ga. one ounce reload. If you discover one, please share.
The 28ga is just not set up to get the speed out of the one ounce load. I believe the velocity on the factory Winchester field load is LESS then 1100 fps. In short the one ounce load is junk and all the one ounce handloads I have tried have not performed all that well either. If you center a bird with a Federal Premium 3/4 ounce load of copper 6's it will die.Jeff
winchester's X28H6 which is one ounce of number 6 lists right on the box 1205FPS and i have chronographed a couple from numerous boxes and find that velocity to be accurate. $16.00 per box however.
i am currently loading one ounce with 15 grains of alliant 2028 in the new style winchester hull (HS) with the ballistic products wad illustrated in the above post and they are going almost 1300fps over the chronograph. 2028 solved my problems loading the 28 ga.
i have patterned the 1 oz loads extensively in our underground range and they are excellent. i use a beretta o/u exclusively for upland birds including pheasants and prairie chickens and the 1 oz loads are very effective. as i said earlier, the new alliant 2028 powder has changed the picture for loading 28 ga. the volume to energy ratio is very good. i think it only takes a 17 or 18 mec bushing. btw, i have weighed the shot, counted the pellets and weighed the powder carefully to make sure that i get accurate results. the winchester factory 1 oz loads are very good as well but pricey. the other thing that makes a lot of difference is the new winchester hulls. they are the best. i have some remington sts and they will work for one ounce as well but better or 7/8. its hard to get more than a couple good loads from them. the ballistic products wad is the only one i know of that will work for 1 oz.
i use the old aa cases for th 3/4 loads for quail etc.
why? because i love to shoot my 28 ga. guns and having 1oz loads certainly adds to their versitility and i don't see recoil as a problem even though the gun is 6 lbs. here in south dakota, its easy to walk several miles a day hunting and i get to like a really light weight shotgun.
