[QUOTE="freddiej, post: 1698574, member: 26227"] I have a few very good pieces of advice from my 1,000 yard shooting days. #1, no matter what anyone else has told you; shooting any slug over 185 grain long distances in a 1:10" twist is not good. I shot 190 grain Sierra matchkings regularly. I found that out when I shot an experimental load with 200 grain slug (sierra MK's) at 1,000 yards; I missed the mountain the target was attached to. I also learned that 1:10" should never be used for a slug over 190 grains. Now with these new VLD's I have come to realize that any slug over 180 grains should be shot through a 1:8" twist. I personally would go with 1:7" if they were made. #2, shooting longer ranges such as 600 yards; just use a 1:8" twist barrel for any slug. I put together a good hunting rifle for a friend and he did not specify a 1:10" twist, I ordered a 1:8" twist and his gun out shoots my 1:10" with the same slugs/loads. my 300 win is getting a new barrel; this time with a 1:8" twist. #3, opinions vary from person to person. I accept that. my personal preference is to use a twist that does not have the words "Marginal stabilization" after the ballistic calculator works out how stable the slug is at 600 yards and 3/4" muzzle velocity. just my opinion, do with it what you wish.
