Those bullets are likely for other .30 calibers. Cannelure depth is cartridge specific for many bullets.

The bullet manufacturer usually specifies the cartridge.

The 150 is a Hornady, right?

As long as the OAL is within specs, the cannelure can show.

You need to follow the mfg of the bullet suggested COAL. Just cause the general suggested mag length is 2.80 does not mean that each bullet design is meant for seating at that length? You should invest in several reloading handbooks.

Those are not seated deep enough. They need to be seated to the cannelure and then crimped.

For .308 Winchester the 2.800 is the specification for MAXIMUM allowable overall length.

Not all loads are seated to the max, many are seated less than the max. Check the loading books for the real OAL for each specific bullet type/weight.

Example: In my Lyman reloading book 150 grain 308 rounds are loaded to 2.685.
165s are loaded to 2.780

You might email the specific bullet companies and ask for some recommendations if you cannot find them in reloading manuals.

It also depends on the rifle. I can seat 168 Sierras to 2.950" and still have a bit of jump. Shilen chambered .308 Win.

I seat my bullets as long as possible. They should be just shy of the rifling by a few thousands of an inch. I personally dont worry about crimping. You didn't say what rifle you were using. If I were using an auto loader I might crimp, but I dont crimp for bolt guns. Have you tried chambering your rounds? Do they go in without any interference? If they do your good to go, if not seat them in until they do.

yep chambered and remeasured with no change in oal, its for a remmy 700

Do SMKs like to be right off the rifling?

I load my Remmy to mag length but wouldn't mind loading a few for ultimate accuracy testing.

In .308 with 168 SMK's...Ive gotten my best results just shy of the lands...
FGGM is mag length with 168 SMK's and PLENTY of jump, yet they are excellent accuracy rounds.
