It seems that very few people reload with Lapua bullets and Vihtavuori powder here in States, so information in languages other than Swedish and Finnish seems to be scarce.
So, I wonder, had anyone here had any experience reloading 308 Win with Lapua brass, Lapua 11gram (170grain) LockBase bullets AND Vihtavuori N550 powder? N150 is single-base and it's all relatively simple(in terms of getting used to its behaviour/performance). N550 is double-base and is supposedly designed to provide most consistent performance under varying environmental conditions (sort of like Hodgdon Extreme series of powders). But interestingly enough, in 308 Win, Vihtavuori manual suggests that the accuracy load for 170 grain LockBase is the one with N150 - 45,5grain at 2734fps MV from 24" 1:12" twist barrel. I have not tried the N550 yet, so does anyone have experience with N550 in 308 using 170gr LockBase? What about N550 in 308 with 185grain Scenar or D46? Thanks! |

I use VV N540 in a 6BR, with 105-108 missles for 600 + yard shooting. I can get more fps than Varget. Lapua pills in 6 mm. are so consistant in weight, that I would venture to say the .30 cal's probably are. If you go to benchrest.com, you will probably get a lot of responses.

I have use .308 Lapua brass now as a SOP. I load them for a Remington .308 w/ a 1 in 12 twist barrel, with either 168gr. SMK's or 155 Lapua Scenar's. Both bullets get loaded with Varget.
Both bullets are very accurate and will shoot sub moa. |

I've used 64 pounds each,of N150, N550, N160 and N560 powder since 2001.
I like the 550 series for 175 grain bullets in gas guns, the 150 series for 175 grain bullets in bolt guns, and the 160/560 series for heavy bullets in 22 cal and 30 cal in bolt rifles.
It's decent powder with a larger velocity swing than the Hodgdens stuff and a huge knee in the velocity curve below 50 cegrees F. I do find the accuracy slightly better with VV powders but not enough to keep a data book with 10 degree temp swings when the H series powders offer an advantage.
Think of VV powders as teh EU equivilent of the IIMR series.
I have not had a need to invest in the Lapua bullets as yet. |

Mr. Mike, what's your powder of choice for a 168gr. SMK in a .308 bolt gun?

CT, I never found a use for 168's in a 308 so I can't help on that account. |

Now you all have me thinking about reloading.I have been looking for a round for my new 308. As of now I am shooting the Winchester ballistic silvertip 168gr. What do you all think about 150gr bullet for deer at long and short range? Or should I stay with the 168gr? |

44 thru 45.5 grs. varget with 168s is a very popular load. around 2650 155 gr A-max work well and with 47 grs varget will get you into the 2900 fps 308 in 26 in barrels. 168's are best out to 500, and as load that will work well across a series of guns, (make one load that works well for 5-6 308's) it is good to standardize. if you are limited to 308 past 600 yds, something in the 155,175 gr is the most popular. LIke ballistic coefficients, most of the accuracy and velocity results are done with rifles having little resemblence to reality guns, and all figures should be taken with a grain of salt, and verified in the particularities of your gun.
