Remington, Premier Copper Solid Sabot, 2 3/4" or 3". It's a 1 oz, hollow point all copper slug traveling at 1450 to 1550 pfs. Very accurate in my Mossburg and they hit hard.
I just use plain old Remmington Sluggers. Brought home many a deer with them in both 12ga and 20ga. Right on in my Mossberg 500 12ga/24in smooth bore slug barrel and in my New England Arms smooth bore modified choke 20ga. Most shots were anywhere from 50yrds out to around 125yrds or so.
Winchester Gold Partition...3" high @100 yds = dead center @150. More accurate and better range than my .35 Remington that I CAN'T hunt deer with in Indiana!
I've tried about all of them- SST's, Copper Solids, WW Supremes, Buckhammers, etc- and went back to good old Brennekee 2 3/4" short magnums this year they're hard to beat and are suprisingly accurate out a rifled bbl. with no leading problems in the bore.
