Lapua .310 Diameter Bullets 200 grain Full Metal Jacket Box of 100

These are the original D166 bullets for the Finn Mosin-Nagant rifles, especially for the M39. I bought these for a Finn M-N 1891 sniper rifle and still working up the load. N140 and Varget hold promise. My review is to make know the QC on the weights of these bullets. Weighing 485 bullets, here is the distro results: 200.6gr 10.5%; 200.7gr. 27.8%; 200.8gr. 36.7%; 200.9gr. 17.9%; outliers (200.3-200.5gr & 201.0-201.1gr.) 7%. If you use the mean of 200.8gr. and allow a 0.1gr. variance, 82.4% are in this range. For precision shooting over 300 yds., this is useful to know. FYI: On YouTube, Iraq8888 has a great review and reloading data using this projectile.

This is the bullet to make D166 Bullets for a M39.

You can tune this round to the stock iron sights.

The bullet illustrated here is not quite correct for the D166. It has the unique Lapua stepped boat tail. (You can get a better idea of the actual shape by looking at the Lapua 185 gr .308 bullet, which is the D46 in Finland. https://www.grafs.com/retail/catalog/product/productId/9562 ) The 200 gr D166 also has a crimp groove.

The stepped boat tail design provides much better sealing - reduces or eliminates blow by - in a worn barrel. It works like a flat base FMJ but still provides the ballistic efficiency of a standard boat tail.

This bullet mikes to .3095" at its major diameter just behind the crimp groove. As the other reviewers have pointed out, this is the definitive bullet for the Finnish M39 or the M28/76 match target rifle built on an M39 barreled action.

I have a couple Finns and these are the most accurate I have found.

I have tried several other bullets for my Finnish M39, but the D166 Lapua are by far the best. I can easily hold 1.5 in. groups at 100 yds. all day with these, whereas other makers give me at best 2.5-3 in. groups. So glad Graf got more of these in....

I love to get all the accuracy I can out of a M39 Finnish Mosin and these bullets are just the thing. IMR4350 powder and these go well together. N140 if you can get it!
