trim length for 6.5 Creedmore

[TackDriv3r]

About to start a load development on my new custom built 6.5 Creedmore, but don't have the modern reloading manual for it. I googled some loads from Hornady and Nosler, but I don't see the trim length, would anyone know? Thanks

SAAMI specs is 1.900" - 1.920". Most reloading manuals are going to split the SAAMI specs.

Would you think 1.915 is reasonable? The fire formed brass varies from 1.918 to 1.922

See if it fits in your chamber

They all fit in just fine, I just like to trim all cases to same length.

If it fits, then keep it longer is my rule of thumb.

Why not find the distance to the end of your rifle's chamber and trim accordingly?

I have found that some rifle chambers are quite long so there is no need to trim for many firings.

If you have access to a lathe you can make your own. Thanks to Varmint Al. Here are his directions on how to make you own. I used aluminum or brass.

I should get one of those, I'll check to see they have a set for all calibers. Looks easy and thanks
