I use Lightfields also I have a remington 1187 with a hastings rifled barrel. I can shoot 1 inch grooups at 100 yards using 2 3/4 inch shell. I find when you go to a 3 inch slug you loose accuracy I chose to stay with the 2 3/4 cause it works. I know there are some new slugs out for this year and every time something new comes out I try it. I have not found anything better then my lightfields as of yet.
I shoot an 870. I always used Winchester Supreme. I thought they were discontinued when they made the Partion Gold. I could not buy the Supremes anywhere so I tried the Gold. I could not get them to pattern. The first five I shot from my gun was going right through a tree that I used for a backstop. I then tried Lightfields and they shoot good. Never tried the Platinums.
I have a mossburg 500 and I still haven't figured out what to shoot out of it I think I will try lightfields if that what Woj says he shoots out of his. I have an 870 with a hastings barrel and it shoots Barnes expanders very well.
My main shotgun is my Remington 11-87 SPS and it loves the 2-3/4" Lightfields. My Mossberg 835, and 500 also love the Lightfields. 3 of my friends also have the Mossberg 500 and they also use Lightfields
I am a huge fan of the Winchester Partition Gold .....Huge...I have shot them all out of my Rem 11-87 and this slug can shoot easily out to 150 yrds...at 1900 feet per second. My results are awsome....They group well and they have been devastating on deer.....Of course, you need a rifled barrel for such success......Dave
