Painless load development (mine)

[Formidilosus]

Formidilosus - I've read a lot of your posts and Just coming onto this thread, which makes a lot of sense.

I have tried the "find the lands" method before, and it seemed to work with .243win, 95gr BT and 7828 for about 3000fps.
I loaded different charges and shot for groups, OCW style. All of them were good (good equipment should give good results ), however the slower powder seems to fill the case a bit
I have a bunch of 7828, but also 1pb of RL17 and am going to try that.

Assuming no limitations due to magazine length, does the "boattail to neck-case junction" means the flat bottom of the bullet? or the beggining of the boattail from the bearig surface, or in between? I assume start of the boat-tail, but want your clarification

Different bullets will have different boat-tail length, so they could encroach on the case more than others. At the same time it seems easier than constantly chasing the lands

The start of the boattail at or above, the neck/shoulder junction of the case.

Thanks guys. It is kind of what I have been doing, though based on a different premise. Will try things using this method. I assume for flatbased bullets like Partitions (which I shoot in the 7mmRM) the same applies ie. Don't seat deeper than neck-case junction
Has there even been the case that too long bullets kiss then lands and end up deeper down? (Would have to seat to lands not case-neck)

Yes. Opinions vary, but I always try to stay at least 0.020 off the lands

...and depending on the cartridge/bullet combo, seating this way can force COL longer than mag length. In a Tikka its no biggy as a quick change of the bolt stop and mag alleviates the problem. I've done this for my 7-08 (162 ELDX) and 25-284 (134 ELDM). Both have LA stop and mags and function flawlessly.

So reloading for a Tikka 6.5 prc. Rifles has about 50 rounds down the pipe so far.

I’m new to reloading. This is virgin brass. 58 grains of N565 shooting the 156 Berger’s. Bullets are seating approx 20 thou off the lands. Average velocity is 2980 fps.

This was an 8 shot group at 100

This look good?
