Are 80 grain bullets larger than 100 grain?

[Hunting4fun]

I found some Winchester 243 bullets that were not in a box. I am pretty sure some are 80 grain and some are 100 grain. Some of the bullets are a fraction size longer than the others. Does this mean they are 100 grain? The larger ones are silver and the smaller ones are bronze.
Thanks

Edit the title should read are 100 grain bullets larger than 80 grain.

Are they factory rounds or reloads? If reloads then I would not shoot them without pulling the bullets, full length resizing the cases and then reloading with fresh powder that I knew was correct.

Weigh them

If you can , weigh them.

I assume by "bullets" you mean loaded cartridges? OAL may not help you determine which is the heavier bullet because they made seat the longer ones deeper and the shorter ones shallower.

Weigh them first. Data i looked at shows around a 5gr. difference in powder weights at max loads. 20 gr. difference in bullets. Winchester cases shouldn't weigh too differently. Looks like you maybe able to get close with comparing cartridge weights. Other clues like oal might answer. Other than that, pull one bullet and seal the answer.

The word “found” in your post is scary, I’d chunk them.

weigh them?

[bboswell]

chunk them and move on

Depends how much copper and lead they have

If you know for a fact they are 100 or 80 grain, who the manufacturer is and that they are in fact for a .243, then I would weigh each one and get them back in their respective box.

It is not as important to know the type of bullet, for example, ballistic tip, hollow point boat tail, soft point etc. because most load data is going to be for the weight of the bullet by each manufacturer and not the bullet type.

If you can’t do that, chuck them. At the end of the day, why take the risk?
