The 30 gr bullet as well as the 25 make contact with the lands well past the case neck. There’s not a whole lot of distance between the base and ogive. Im seating both bullets way off the lands. My pressure issues have been with overcharging because of having no real world information my mistake. I shot two five shot groups with 25 Gr bullets 22.4 gr of H4895 from past reloads Both right at .5.
All my panic and hysteria was because of my misinformation and ignorance I do appreciate you guys holding my hand and helping me out pointing me in the direction of using common sense and having accurate facts

In the 17's there is a big difference in bullet shape. This can put the ogive of the bullet, ogive of the bullet is where bullet first makes contact with the rifling. An example, Hodgdon has a Berger 30gr coal 2.150" . When you look at that bullet it has a lot of bearing surface below the ogive(less length taper to the bullet tip) compared to a 29 gr WCD (Woodchuck den) hp. The WCD I can load coal 2.195 in a minimum SAAMI chamber (custom reamer). So be careful using data that doesn't use the exact bullet you are loading. That bearing surface length makes a big difference in pressures/velocity and likely which powders will yield the most efficient powder burn and to some extent accuracy. That ogive position can also change the % of case volume fill by type of powder. You being somewhat new to the 17 Rem, I would avoid 100%+ (compressed loads) as pressures can spike very quickly(small charge weights variations like 0.1-0.2 gr). 0.1 grain is often the +,- error of common scales.

Anytime you change bullets, or even lot numbers of the same bullet, you need to re-check seating lengths.

I don't typically get down to the last thousands like in the vid. I make a dummy round & smoke the bullet with a Bic lighter and look for the land mark on the bullet. It doesn't really matter how far in the lands you are, it's just a repeatable reference point for seating with that particular bullet & lot number of that bullet that you can adjust seating lengths from.
Seating into the lands raises pressures & you run the risk of sticking a bullet in the lands & dumping powder all over the action if you don't fire the round in a hunting situation...... BTDT.
Typical mark I look for when finding the lands, which is somewhere around .015-.020" in the lands.

Do you have a set of calipers?
Reason I ask is you keep saying way off the lands etc etc, yet never mention a dimension for a COAL ( cartridge Overall Length) or for a CBTO (Cartridge base to ogive).
here is a link to Berger web site addressing COAL and CBTO Just in case it is confusing to you

After thinking about it, I reached up on my shelf of actual reloading manuals, yeah Books with paper. Pulled down the Lee manual 2nd edition.
Went to the 17 Remington and did find data for a 30gr bullet start and never exceed amount listed with powder choices..
Richard Lee was bad to pull all the data he could find and put them in one book without citing source.
Looking over the data the Hodgdon web site to that book is a dead ringer, as in same data .... maybe try there for a source until Vitavoha responds with some data for your 30gr bullets? ( at one time Berger offered a 30gr .17 caliber so they might have data, try contacting them?)
