Measuring CBTO to calculate jump onto lands leaves rounds too long for magazines

[RPRlongshot]

I have used a Hornady comparator to measure the contact with lands on several different bullets.
Noslers and Hornady bullets can be loaded to fit in my magazines when set for a .015 jump but Sierras are different.
The Sierra match kings when set .015 from the lands are much too long to fit in a magazine.
I use a single shot adapter on my RPR with good results.
In the sticky for .308 loading I see some accomplished shooters listing the AMAX bullets at a specific jump but the Sierras set at magazine length.
Is there a reason I shouldn't go so long with the overall length?

Seat the bullet to mag feed unless you're shooting a comp that requires very long for caliber bullets.

Yeah, as you said "They wont fit in the mag."
Other than that no.If youre fine with not feeding from the mag then dont worry about it. I would try them at mag length or shorter though if you are up for the testing, lots of shooters jump more than .015 with good results while still being able to mag load.

Also in regard to the title by definition the OAL (over all length) is not the ogive.

Ya, you're talking about CBTO. I'm gonna assume you're also talking the 168 or 175 gr flavor. Have you shot FGMM outta this rifle? And if so did they perform well and feed with no hitch?

FGMM 168's have a COAL of 2.800ish and a CBTO of 2,225ish ON MY COMPARATOR

FGMM 175's have a COAL of 2.805ish and a CBTO of 2.230ish ON MY COMPARATOR

You can do Dan's sleuthing tip and adjust seating to your desire more than likely within mag length. Good luck.

And go figure, just below a bit there's a thread speaking of FGMM. So there ya go.......
