Omegalover ,We all have our preferances,my Omega Likes the 50/40 200gr Shock Wave and it shoots it with max load into a very tight group.
The weight thing,since the 40 stands for 40 cal. the bullet is long about 2 cal long this helps give good sectional density and BC to go with the high volicity. The 250 is a very good all around bullet and I think had to beat when the gun likes it.I like the .475 cal. 325gr For Hog and Bear and if I ever draw an Elk tagI will use 300gr they will all shoot good enough with the right load.
