Alright to start off with I have googled this numerous times switching up the wording trying to find an answer with no luck...so I'm making a post. I am just getting into reloading and I am going with the 175 Nosler CC, CCI-200 primers, and Varget as powder. On my first test loads when measuring for OAL I kept getting a different #. Ex. 2.8155 for one 2.8100 another etc etc. Is it better to measure a HPBT at the ogive instead of the tip? And if so what is the name of the tool I need to put on my calipers to do so. Thanks for any help I may receive.

Yes, measure from the ogive. Get a comparator tool:

Re: Couple simple questions
I'll disagree a little bit. What is your mission? Do you want a certain distance off the lands or are you concerned with the OAL length fitting your magazine?
When seating, (if you are a good, decent person), your seating depth is very consistent, because the seating stem positions somewhere along the ogive, not the very tip.
So, you say that you are just getting started. Are you already involved in match shooting, or considering competition? There are many serious shooters that don't bother with a comparator and probably cannot hold a rifle accurately enough to judge the difference between variations in seating to a precise ogive distance. These are questions that can drive you nuts, if you let them. BB

Re: Couple simple questions
My mission is to create one consistent, accurate load to shoot either for fun and or competition. No need to have 3-4 different dope charts, and with the 175 I should be able to easily reach 850yds which is the longest range I have available to me in my area. As of right now I only shoot in USPSA pistol competition, and I'm venturing out into precision rifle.

Re: Couple simple questions
A Hornady "Head space" AND "bullet comparitor' kit for your caliper is the tool to do what you seek. No weapon cares where a bullet nose hangs in space but they do care about bullet jump before hitting the lands.
But, it won't do you no good; all us boys from Oceanway know you fellers up to Yulee kan't shoot good no way.

This was from how I shot @ 200yds with FGMM 175 at Lake City on Monday. Pshh Yulee boys can't shoot.

I don't think you need that comparator thing to accomplish your mission... Realistically, you don't care how far your ogive is from your lands, what you care about is that the bullet winds up at the same place consistently when you do everything the same. The comparator isn't going to tell you anything about what seating depth will do that, only loading different seating depths and shooting them will.
I guess maybe, the comparator will allow you to mess with your die, and set it back to the same exact position a bit more precisely? But for that, I'd guess that measuring to the tip is going to be close enough.
*caveat, I'm new to reloading, but my loads are good enough to get me hits at 1k, which is all I really need out of them.

Re: Couple simple questions
"I have normally been making the trip to Bradford but they were closed."
Is Branford's "Steamboat" motel still in business? (Not much but I took a lot of SCUBA classes there long time ago. And, yeah, this is personal and 'off topic' for a couple of home boys but it is SHEEPDOG'S topic!

Re: Couple simple questions
I had comparators and ended up selling them. It was more money in crap that really didn't make a ton of difference in the end. I found that the variance in bullet lengths, which can affect other things, is generally so minor its a zero sum game. I quit searching for perfection a long time ago. Dont make it hard on yourself. Keep it fun.

depending on the quality of the caliper you have - your accuracy in measurement is likely showing the inconsistency of the tool you're using. Unless you went out and spent a few hundred on your calipers, or you're using a quality micrometer to get your OAL.... well yea. I know my $40 german calipers arent that consistent or accurate - nor do i expect them to be. but they're good enough for what i'm using them for
a parting shot... if 0.0055 of varience in bullet seating depth was enough to cause problems in a firearm - we'd all be dead now........ i havent measured it to be sure, but i'm comfortable to say the varience on factory ammo even within a given lot is easily 2-3x that difference.
YMMV

Re: Couple simple questions
My calipers are $114 and are calibrated once a yr unless dropped. I work in the aviation field and its mandatory by QA to have them calibrated. Be either way I purchased a Hornady comparator to measuremy length with and I plan on matching the length of FGMM 175 to start with.

Re: Couple simple questions
Have fun and check back in 3 or 4 years and tell us how it all worked out for you. The thing is, some guys don't do any of this shit and yet they beat your brains out, at the range. Figure that out. BB
