Trouble with determining base to OGIVE measurement in 28 nosler. Using Hornady OAL Gauge. PLEASE HELP.

[Kylerjay05]

Hello. I would be greatly indebted to anyone that can shed some light on my dilemma. I am trying to determine where my bullet hits the lands in my rifle to work up some new monolithic loads. When I use the gauge, I repeatedly retrieve the modified case and find that my rifle is allowing VERY long loads. If someone with an abundance of experience can help me, please send a DM. I'd really appreciate the chance to talk it through. Thank you!

The bullet is probably being pulled back out by the rifling, are you pushing it back onto the pin before measuring.

I about chucked my Hornady OAL thing in the trash. I use this method:

I am. I set the pin before removing the oal gauge. Then I push the bullet out with a cleaning rod, put the bullet back in the gauge, and measure. It's very long.

It is possible that you have a very long freebore. What rifle?

That's what I'm thinking. I am shooting the savage 110 ultralite chambered in 28 nosler. I wanted to experiment with various seating depth, including an option to have it set to almost jam point. But if I were to do that, the Ttsx bullets I'm hoping to load would have multiple rings exposed beyond the neck of the case.

Having a ring exposed isn't necessarily an issue but multiple exposed is interesting. I think you'll find those bullets like a bit of jump anyway. Is it longer than mag length while touching the lands?

Don't jam mono's your starting pressure will be excessive. Mono's usually like a considerable jump to the lands, 050" at a minimum. I have bullets that jump well over .150" and shoot great. Usually end up loading to just under mag length.

If the results are somewhat repeatable I'd say you probably just have a hallway of a throat or the bearing surface on the bullet you're trying to shoot could be short. Either way, most people say mono's like more jump, especially from a pressure perspective. I would seat them at least a calibers depth or more and send it.

I ditched the Hornady OAL gauge for the cheaper and more effective Frankford Arsenal cleaning rod gauge that actually measures from the bolt face, it doesn't require modified cases and is plenty consistent for determining a measurement to the lands.

Either there is enough bearing surface in the neck to hold the bullet sufficiently or there isnt. I'd trust your results. I dont load barnes much but just took a look at the 127 LRX i have. With that bullet an ideal seating in a 6.5 would have both of the rings in front of the case mouth.

Edit: looking at barnes pics on their website, if you dont have two bands showing i'd argue it's seated deeper than ideal anyway.

I didn't get to the point of checking that yet just because I knew i wasn't going to load it with those measurements. But I would suspect if i ran any load at jam point that it wouldn't fit the magazine in my particular setup.

I appreciate all you fellas... these forums never disappoint.

I appreciate ya. It just looks so bizarre to have 2 bands showing and a chambering that is sooo much longer than what the reloading manuals will list as MOAL... is that fairly common?
