[QUOTE="Fiftydriver, post: 181029, member: 10"] Titanium, I ordered in three 500 count boxes of 300 gr SMKs last summer. Same lot number on each. Measured all for baring surface consistancy. Sorted them in groups as follows: "-0.003" +/-0.001" "0.000" +/-0.001" "+0.003" +/-0.001" Basically, I had three lots of bullets with baring surface lengths eithin 2 thou . Of the 1500 bullets, this was the results: Group "0.000": 1189 bullets Group "-0.003": 137 bullets Group "+0.003": 91 bullets There were 83 bullets out of these Baring surface ranges. 51 were shorter in BSL then -0.003" and 32 were longer then +0.003". When I was sorting them for BSL, I also started weighing them. I went through the first 500 and none of them were more then 2 grains different in weight. That is not even 3/4 of a percentage point in weight variation with a 300 gr bullet and well under what I feel will effect accuracy more so them actual human error shooting the rifle. I stopped weighing them after that first 500 bullets. As far as the BSL comparisions, which can make a dramatic shift in vertical spread at long range, Just shy of 80% were in the zero lot of bullets. 9% were -3 thou and 6% were +3 thou. Only 5% were out of these ranges. Personally, I think thats pretty **** impressive but I can not say on the other calibers as I have not done this type of sorting on them. As far as bullet flaws from bullet makers, I have seen Partitions with no front core in them, I have seen Ballistic Tips with no tips on them, I have seen Hornady and Speer bullets with the jackets upside down on the bullet forming a FMJ when it was supposed to be a SP. I have seen Sciroccos that had severaly deformed tips, Not from damage but lack of plastic when the tips were formed. I have also been able to pull the tips out of these bullets at times as well as they were loose from the factory. Simply put, to some degree, I believe I have found at least one example of a flawed bullet from most of the major bullet makers. I did find one batch of Sierra Blitzkings that has deformed tips as well. Was a box of 500 50 gr 224 BK bullets. Called Sierra up and they sent out a new box no questions asked, did not even want the old box back. Point is, put out millions of bullets a year and never having any issues is hard to expect. Now no cores is a big problem but I am sure if your buddy contacted Sierra, they would get him new bullets ASAP. From what I hear, sierra bullets are still winning more matches them any other bullet in the high power matches. I may be wrong on that being as I am a big game hunter, not a BR shooter but Sierra is still the name for most long range shooters not using custom bullets. Kirby Allen(50) [/QUOTE]
