Can someone advise me of the best method of finding the best bullet seating depth for the lands on a Savage 10fp bolt action rifle maybe a gauge etc.? Thanks!

Re: .223 rem bullet seating depth question
You could do it the old school way and chamber a dummy, but I never had any real luck with this method, as the bullet sometimes gets pulled out a bit upon extraction.
Of the 3 dedicated tools I have tried, I really like Sinclair's tool. It is the best built, and the most repeatable of the 3. Check it out on Sinclair's website.

1) seat a bullet at least 0.3" long in unprimed unpowdered case
2) carefuly insert into chamber
3) slowly and carefully slide the bolt to engauge the case and slowly and carefully close the bolt.
4) slowly and carefully open the bolt then slide the bolt back far enough you can use your finger to prevent the cartrige from getting thrown by the ejector.
5) measure OAL (or more optimally the ogive position)
6) repeat until you have 3 sucessive measurements that are withini +/- 0.001

You can use the method described above, but I never had any luck with it.

+1 This is what I use as well. Easy and works like a charm.

Re: .223 rem bullet seating depth question
i use sharpie covered bullet but same method, you can see where the lands rub the marker, then you can move back from there.....

Do yourself a favor. Gather as much load data as you can, pertaining to the powder and bullet that you want to run. Decide what velocity you want to launch at and fill the cartridge accordingly. Then, simply make up 5 loads at, say, 2.220, then 5 at 2.240, 5 at 2.260, and so on, up until your bolt will not chamber the load. Then fire away.
I was just out today working up a .223 load and did just that and got amazing results!I started at 2.220 wit 26.5g of BL(c)-2 and a 69 grain SMK and got about a 1MOA group. Then I went to 2.240 and, with the exception of one flyer caused by me, got a .3MOA group! Same charge, same bullet. From there the groups started spreading back out. I only had loads out to 2.280 today, so there is a possibility that going even further out will start to tighten the groups back up. Regardless, just messing with bullet seating depths will yield HUGE changes to the accuracy of a load...
