- 6mm dasher 90gr scenar-l
I have used them . Did not see any difference between SMK 107s or the Bergers. Just my two cents. Tommy Mc In my Dasher.
This is my findings so far. I jam the lands and backed off .020
CBTO 1.840
First series I deleted 1 shot that was way out of line with the rest. It was a cold bore and the bullet I used to find the lands so Idk.
I did 5 rounds mainly to get a good MV. Groups suffered from it. Group sizes were measured from outside to outside of at the furthest point then subtracted bullet diameter .243.
Shots all felt clean. I think I am going to try seating depth on the 33.3 load to see if I can maintain the velocity ES but tighten the groups. Also curious to see what the MV will do adjusting the Seating depth.

In a 6BR, about .006 past first lands touch, these shot in the ones for 3 shots, easy mid-twos for five. Velocity node was very broad — you’ll find they go quite a bit faster than the 105-107 class of 6mm Bullets.
The 90gr Scenars we had from a few years ago also showed outstanding consistency in base to ogive measurements.

So i tried backing off .003 increments from my starting poing with 5 shots. I wasn’t happy with the results at all. My ES was still good so I like the 33.3 of varget.
So then after some advice from a friend I decided to jump .020, .040, .060, .080, .100, and .120. Here are the results... photo. Next i will group at 500 and 1000 yards.
