Remington Core-Lokt factory ammo 175 grn
pulled 8 bullets and weighed powder and bullets to see exactly what i was getting and to determine if i wanted to just pull bullets and save the powder and bullets for later date plinking.
results: bullet weight grains powder weightgrains
#1 174.6 64.7
#2 174.5 65.9
#3 175.7 66.1
#4 175.5 66.4
#5 175.2 66.2
#6 175.2 64.9
#7 175.5 66.2
#8 175.7 66.2
:o and this is why i reload. its not really that much cheaper these days but reults are everything. I figures i would save the powder and bullets in case some day im unalbe to get my regular stuff!!

Those core-lokts are on the inexpensive end of the spectrum so I'd expect inconsistent results I guess.

You can't compare the cheapest stuff in the stores to your reloads when your reloads are a much better quality product.

ive been weighing our berger 168 grn vlds they have been within .02 of 168 grns. havent checked my noslers yet. always thought core-lokt to be ok cheaper ammo but it explains the occassional flyer.

Not a reloader so don't call me a dummy but how much difference does .5-1 grain weight difference really make? Big difference or a "you have to be OCD to notice" difference??When I was tuning my current load for my .270, the difference on average group size of the load that was 1gr difference from my final load was almost 3". Half a grain was over an inch larger average group.

Big difference or a "you have to be OCD to notice" difference??Could be huge, especially with smaller cartridges where a 1 grain gain is a much larger change in percentage of powder. Also, the geometries of certain powders will give more of a change. Some will be light flakes and you are adding a lot of small flakes to make up that extra grain, some will be cylindrical and could only be a few pieces.

Anyone try pulling Nosler ammo? Curious how it compares since I get great accuracy from it.From a reloading and not a pulling assessment, I have yet to find a weight variance greater than .03. The .03 was in a box of 180 gr ballistic tips for .30 cal.
In spot checks over the 30+ years, the norm in weight variance is .02. Partitions primarily are what I use.
This is for .25, 270, 280, 284, .30 and 338.
I used to be really anal early on and weigh every 175gr Partition for my 7mmRM. I quit trying to find a problem and just check 6-8 in each new box I buy now.

To expound on what one said regarding a load "tuned" to your barrel, if the factory load happens to be "tuned" to the barrel, small variations in powder charge may not make much of a difference, for a hunting load over moderate hunting distances. If not, then such small changes could be quite a difference. See discussions of ladder tests and determining the node(s) of particular load combinations. The adverse results should be magnified with smaller powder charges of smaller cartridges.
As far as bullet weight variations go, I would expect that the same could be said for bullet weight variations, but with a somewhat dampened effect (1 grain of 178 grains is about .5%, whereas 1 grain of 66 grains is 1.5%, even though you probably cannot make a straight comparison due to the different effects that such variations bring about in the delivery of the bullet out of the bore).
Consistency is the key to accuracy.

Major John Plaster noted in his book "The Ultimate Sniper" that Federal has the most consistent ranges. I would be curious about your experiment results if you pulled apart what I shoot: the cheap blue box Power Shoks. I get 1" moa out of my gun and for keeping it to 300 yards or less I don't see any reason to invest in a reloading setup when I can buy the stuff for <$1 a round.
i played with the cheap blue box before..i got moa groups but constancy from box to box was no good...i was shooting 6 inch groups at 500 pretty easy (i was very happy at the time with that)..bear seeason came around,went a bought a fresh box,found bear at 476...easy shot...miss.. :bash: took same box bake to range an was 10-15 inches high at 500.. :bash:
but like you said your going 300 or less..pretty hard to have serous deviations with in 300
