I have read all significant posts on this string, and I must say it is very enlightening. Many say real world data for your rifle and ammunition chosen. I selected 4 and only those 4 (Eley Match, Sellier Bellot Club, Lapua C-X, Fiocchi 320). The rifles I used for one year were Zephyr II 19.7" barrel and the Savage TRR-SR 22" barrel, both bought at the same time. SB Club was chosen because of price vs performance, it would have been CCI Standard but the coating used on the rounds causes failure to extract to often. All of the ammo 2 x 5 shot groups out of both rifles were always within averages, with same lots and environmental at 50 yards, Zephyr II was most consistent shooter. I went once a week missed two weeks (50 times), not mater if it rained. I used the same rests, and same range and targets to include a full reset per shot, real world right. SB Club was used to warm barrel and ensure my zero. Scopes leveled, plumb bobbed vertical, all targets leveled when mounted on board and same target splatter was used throughout. I had 1000 rounds of all the ammo and they were all stored in the same cedar chest.
What did I learn?
Match grade ammo is nice to have and all three shoot just as well as the other based on over all averages within .030 - .180. This included my "F" ups and flyers. The Savage TRR-SR was modified only in torque 30 lbs plus 1/8th" spacers applied to chassis mount screws. The other thing I discovered was the feeding and striation on rounds that failed to fire. The Savage was causing additional marks on the case and bullet compared the Zephyr. So at week 39, I manually inserted all rounds into the rifles. Pain in the a--, Zephyr didn't improve at all but the Savage showed marked improvement. I had 3 ten round mags and 1 5 round mag, so I tested them to see if they were the issue and sure enough all the ten round mags were causing the additional striations on the rounds via feeding, there was a slight design difference in the mags. The 5 round mag was of a tighter spec.
After week 39 the TRR-SR was shooting at times ridiculously tight groups .230 and below at times. The Savage was clearly the better bench shooter based on weight, scope (Arken 6-24x50 34mm tube G2), and bolt action. The Zephyr is my hunting setup, it has less weight and a Athlon 4-14x44 BTR 30mm tube mounted. I attributed the occasional amazing groups by the Savage do to the scope reticle, I put a second Arken scope on the Zephyr II that was one of my 6.5 Creedmoor's and Wela, lights out .300 and below much more consistently, added weight helped. The reticle on the Athlon was thicker.
As I said prior, all match ammo tested were equal in my observations. Zephyr will shoot Fiocchi as prefered, Savage will shoot Eley Match as prefered. They both will use Sellier Bellot as plinking ammo based on cost vs overall performance because 17% of the time it had the best groups. The more frequent fliers were what hurt its groups, if I discounted the fliers they were all moa or below and would have tied for 3rd place.
I will move on to 100 - 300 yards, I will test the same ammo but I will test more to determine best 4 at 100 1st, then go for it... I will record my dope, and see what happens.
The match grade ammo isn't worth bench shooting/plinking it gets boring plus at current price vs return on investment. If you compete, hell yes, but watch environmental, wind, temp, in sun/shade, and humidity. My elevation was constant. I did notice a wide difference, for example at 28 degrees in the shade, zero wind Lapua was the winner in both rifles, when 94 degrees zero wind, Eley Match won both were significant and was the only difference. I didn't have many calm days, my prefered is based on averages, the order or sequence in rotations was always equally rotated after cold bore. So I firmly believe you may want to have extreme temp prefered rounds.
I hope this helps...
