Much as I like the 65x53R/54 mm M-S in my vintage curmudgeon mindset, in medium power 6.5s I think the 65x55 SE is the best. The Steyrs are hampered somewhat by the rotary magazines. Usually loaded with heavy 160 gr RNs. The 55mm shines with 140 gr pointed Spitzers. As well as 120, 125 grs.

The .243 was very popular in Australia. For roos, euros, wallabies, feral goats and pigs. Fallow, chital, hog deer etc.

My opinion is a 6.5 is a better choice for Australia. And better for red and rusa deer, sambar deer should be legal as well.

Louis,vwhat are your plans for this rifle? What will you hunt with it?
