That is some awesome accuracy. Is your rifle all factory? Had any work done to it?

    Rifle started as 700 sps, then (after burning bbl @ 272 rounds!) installed pac-nor bbl,with vais type brake, trued action, minor trigger work on stock rem trigger, and accurate innovations stock, (and much, much range work) with a few conversations with berger i settled on that load. Works for coyotes/antelope/deer/elk.

    I am shooting 180 accubonds in front of 90 gr of rl22, mv 3250 accuracy, one hole! My friend is doing the same with 180 sciracos with 90.5 of rl22. I tried H-1000 and it shot good, just not as good as the rl 22. My next tests will be with retumbo.

    Nobody had any 180 grain barns for me to try out so I went with the 168ttsx and pushed it with 97 grains of h1000 and fed 215 primers and got less than .5 inch groups at 100 yds 5 shot group, 3330fps and a coal of 3.760in I have shot these out to 700 yds and had good luck with them keeping about .75MOA at that distance but it was a little breezy and I didnt have a very good rest so I need to do it again... Barns have a very low BC and dont work to well at longer ranges max effective range with the bullet still performing is 700yds in my rifle..

    If you can get the swift sciroccos to shoot out of your rifle I would go with the 180's for that I had great luck with accuracy and theh have a higher BC and I took a lot of game last year and was very impressed with how well they worked I killed a 150 lb caribou and up to a 1500 lb moose with them and nothing went farther than 20yds but I cant get them to group out of my RUM (damn)

    I've been fooling around with the 208 A-Max which I intend to use on whitetails. I believe the BC is .648 and should be good for the looooong shots. Yesterday I loaded up 99.0gr of Hodgdon 869 with a 215M primer. Shot a .55" (3 shot) group @ 200yds. Pressure seemed modest as bullet cruised along at 3,035 ft/sec.

    Not exactly neck breaking velocity but incredibly accurate. I'll load up some more and see how they shoot at 300yds.

    I'm also interested to see how an increase in charge weight affects velocity and accuracy. Currently shooting a 27" Broughton 5C.
