RE: 1:48 twist 50 caliber
My New Englander will shoot a 385 Gr Plains and a 260 Nosler Partition inside 2" at 100 yds It will do it every time--however I cannot. Seriously both these loads are very accurate in my rifle. 80gr BM3 for the conical and 100gr 777 for the sabot. I have to have a good day to group that well with open sights.
