This in from another board.

YES, I KNOW I AM YELLING! OK, I just checked the jam length measurement on a new batch of Sierra Matchkings in my 12BVSS-S, and the length measured puts the bullets INTO the lands .020" when the COAL is loaded to the specified 2.260". WATCH OUT YOU GUYS! The last thing everyone needs is a pressure test gone bad, whether they were looking for one or not. This isn't a problem with my rifle, I've had other lots of SMK's measure just fine. Again, please be careful. I'm not real inpressed lately with Sierra's bullets; on the last batch I measured the distance from the base to the ogive, and got over .050" variance. Maybe someone should tell the QC department at Sierra to WAKE THE **** UP, PEOPLE ARE GOING TO GET HURT!

BS!

OAL is determined by the bullet being used and the chamber/magazine in which the loaded round is being used.

What works for one firearm doesn't necessarily mean it is "bible" for all firearms.

Besides, it is alway recommended that any time ANY component is changed (and that includes lot/batch numbers) the load be re-worked.
 
What the guy is saying might make sense but I'm not too worried about it at this time. SMK bullets have always been great for me but I'll have a look at my new box when I next load to be safe.

No #### Sherlock but people have made mistakes before and people will continue to do so. It isn't BS at all with the number of reloaders out there that do not know how to check ogive differences or OAL for that matter. If by chance someone only reduces their load a grain or so and gets a bullet jammed into the lands thinking its a shoulder hitting, there could be an overpressure problem. Unlikely but possible largely due to inexperience and poor methods. Changing the ogive without warning is not a good thing.
 
Your attitude sucks...

That being said, part of re-working a load is checking the OAL of the cartridge when using a new batch of bullets.

There is no way to prevent ignorance...
 
Funny, I thought the same of your attitude when the first words you posted were "BS!"

Re-working, yes absolutely agree. The copy and pasted post above means nothing to you and I but again, to many it does.
