In my 6.5x55 I got started with 129-130 grain bullets and stayed there, this is on deer and pigs, nothing bigger yet. I used Nosler Accubonds, Barnes TSX, Hornaday IB & AB& ELD-X, Berger, and maybe some others I forgot. All of them did well, personally I don't care for the amount of lead and blood shot meat from the Bergers at closer ranges, but they are effective at putting things down. I will give the LRX and the Scenars a try at some point.
The ELD-X is closer to the A-Max in construction. The ELD-M has a thicker more tapered jacket. I liked the A-Max in 70 gr. .223 and 105 in 243, but I think I like the ELD-M better.and will put some to the test shortly I hope.
