gruntus Posted October 12, 2019 Report Share Posted October 12, 2019 Hi All, Looking for anyone with real world application of using heavy bullets in a 1 in 11 twist 300 Win Mag? Currently using 190 SMK and looking for best heavy (Berger or other) bullet for use out to 1000+ yards. All the best G Quote Link to comment Share on other sites More sharing options...

Ronin Posted October 13, 2019 Report Share Posted October 13, 2019 Tells thee reader nothing about what was asked in the post starter The attachment is reference material on policy and procedure signed off on how to carry out accuracy tests and inspection for the 300 win mag at 300 and 600 yds interesting concept on “accuracy” would have hoped the standard to be 50% higher really Quote Link to comment Share on other sites More sharing options...
@nd Posted October 13, 2019 Report Share Posted October 13, 2019 i shoot 220 gr SMK over 71gr RS70 or 72 gr Vit n165 This is in my rifle it may not be safe in yours, work up your load safely . Quote Link to comment Share on other sites More sharing options...

@nd Posted October 13, 2019 Report Share Posted October 13, 2019 1 in 11 twist Quote Link to comment Share on other sites More sharing options...
gyr Posted October 19, 2019 Report Share Posted October 19, 2019 A friend shoots 208 amax and 208eld in a Tikka which I believe has a 1/11 twist. they work very well, but have seen him shoot only up to 900 yds. Bullets were stable abd accurate so they should make it to 1000 with no problem. Powder was tubal 8000. Quote Link to comment Share on other sites More sharing options...
gruntus Posted October 21, 2019 Author Report Share Posted October 21, 2019 Cheers all, I contacted Berger and they recommend 185 hybrids (optimally for the range of temps I shoot) and they also provided for info 190 and 200s to try. Was really impressed with the tech support, they provided load data, bullet stats and velocity ranges. G Quote Link to comment Share on other sites More sharing options...

JBirchall Posted November 26, 2019 Report Share Posted November 26, 2019 The 215 Hybrids would not stabilise in my 1:11 barrel. At the time I went onto the Berger site and the stabilisation calculator indicated they wouldn’t stabilise or marginal but if I remember correctly the 230 (is it the OEM?) showed that that bullet, although heavier, would. I never tried it though and went to using 185 Scenars which performed very accurately. Quote Link to comment Share on other sites More sharing options...
