[QUOTE="goodgrouper, post: 114011, member: 2852"] I would even go so far as to say that it doesn't make much difference even at 1k. I have only really seen bad meplats make a difference on certain bullets past 1500 yards. A much more important and detrimental aspect to accuracy at these ranges is the bearing surface length and the length from ogive to base of bullet. Every bullet I load that will be shot at ranges of 800 yards or further will be measured for bearing surface length and loaded into my ammo box in rows with same lengths. If there are quite a few different lengths in my ammo box, I will make marks on the tip of the bullet with a sharpie to distinguish which is which. I personally have tested several VLD style bullets at 1500 yards out to a tad over 2000 yards and have seen .002" difference in bearing surface make as much as two feet of vertical impact! It is a drowsy job measuring bearing surfaces on every bullet you want to shoot but if you want to be deadly at longer ranges, it is a must! If we could just get bullets for our game that were as uniform as bullets for the 100 yard BR crowd, we would have records being broke on a weekly basis. They have come a long way from first introduction, but there is still room for improvement. I just got through measuring a new batch of Berger 140 grain VLD's for my 6.5-.284 and it was one of the worst lots I have ever seen come from Berger. They must have had their presses all screwed up the day they made this lot because there was .010" variation in length! Terrible. I will most likely just use this lot for varmints and forget trying to shoot groups with them even after sorting them out. Anyhow, hope this helps. [/QUOTE]
