Re: 7 WSM vs. 300WSM at 1000yds
on the 7WSM, stay with 1-9 twist, also sierra is supposedly coming out with a 175 gr 7mm this year.
You can get 2900 with 210s but you need the 30" barrel and best accuracy will probably be 2850-200 max. Now one guy I know with 210s, Win brass, heavy loads of MRP is going over 3000 in his gun, but he is the only one that is able to do that and he has shot some 5-6" groups in competition. However, I have done 2900 easily with the Win brass which I think has a little more capacity than the Norma.
JLK makes a very good 190 and 210 bullet also. Very good tolerances and high BC. I like them better than Bergers but everyone has their pickss/
