reloading question on 30-06
 
Finally got everything to reload my 30-06 and made 10 rounds. Just want to make sure I did and understand this part. Made my round to the max per my book and they wouldn't load in my gun so I kept adjusting the bullet further into the case and then I would put it into my rifle to make sure it would load. I used a match to soot up the bullet to make sure it wasn't hitting the lands and grooves (no ring around the bullet). My question is how far back should the bullet be from the lands and grooves. And how do you know if your rifle likes it closer or further back when shooting? Are the bullets not holding a tight pattern on the target or are they shooting high or low.

No real definite answer, every rifle and every bullet is different. Trial and error is the only way to find out for sure. Just make sure your bullet is seated deep enough for adequate neck tension, the round fits into the Mag, the round cycles and feeds.

Personally, I like to Start at .020 off and go shorter when fine tuning. YMMV.

Not holding a tight "group" shotguns shoot "patterns", rifles shoot groups. :)

Mseric is pretty much spot on. every rifle is different and every bullet is different. that's the beauty of reloading. finding what's perfect for your rifle instead of one size fits all factory ammo.

personally, i use a black majic marker and coat the entire bullet. i make a dummy round for this procedure as the first one. i usually back mine off about .050 as my starting point or max OAL.

I had this problem to. It turned out i needed to full lengh resize not just neck size the brass. Once i did that i was good to go.

Duddie, he's talking about the seating depth of the bullet in the case. not whether to F/L or neck size the case.

seating depth can play a huge factor in the performance and accuracy of the round. a lot of reloaders shallow seat bullets so they are closer to the rifling.

On my bolt actions,I will start at .015" off the lands and run from minimum to max powder charges for each bullet I want to shoot in each rifle. When I find the best load,then I'll seat the bullets at .010"-.020"-.025" off the lands,and try them. Sometimes you will have good results with small changes in seating depth.

On my Semi-auto's,I start at max magazine length,and then work backward on seating depth.

Always look for pressure signs on your brass when working up loads,the closer you seat the bullets to the lands,the faster the pressure will show signs on your brass. You may be nowhere near a maximum load before the signs show up.

I start at .005 off of the lands and work back if necessary.

IME, the closer to the lands, the more accurate.

When I shot .30-06 in competition, some of my loads were loaded way down but actually touched the lands. (but just barely)

I use Sinclair comparators and bullet seating measuring equipment.

I appreciate the help guys. I want to say my are set back around .010, maybe .005. Its hard to tell with the lead tip bullets. Going out to test them out Sunday morning. See how they shoot.

Castor, also remember that if you change bullets brand or weight, that you need to start all over again in shallow seating them, as ever bullet is different. the length of the bullet as well as it's shape.

That's the beauty of the Sinclair comparator. It doesn't measure OAL, but instead measures the length from the point on the ogive where the bullet diameter equals groove diameter. That allows you to change bullet shape and keep the same distance off the rifling.:)
