    I have a few questions regarding bullet seating depth custom to my rifle which is a Rem. 700 Police in .308 win. Using an RCBS precision mic, I get readings of anywhere from .157 to .159 for determining maximum bullet seating depth. In order for me to get one of my bullets to a COAL that will fit into the magazine (not a clip but a hinged floor plate), I need to seat it to where the mic reads -.066 which when you add the two togeter, comes to .223! This is almost 1/4" that the bullet needs to jump before it contacts the lands of the rifling! Two of the other bullets I'm loading need to be seated to a reading of -.020 in the mic which still puts the bullet having to jump .179 to the lands. If I remember correctly, my last bolt action I had almost 1/8" to play with before fitting in the magazine became an issue and this would allow me to get the ogive to within .020 or .030 from the lands. My first question is this: Does this sound normal or could there be a possible factory defect with my rifle? With this rifle, I have loaded rounds that were too long for my mag where I had to feed them one at a time into the chamber and got teriffic accuracy. The loads that fit the mag are not giving me terrible accuracy. Since I'm wanting to acheive superb accuracy, am I going to have to live with the fact that I can only load one at a time? Any comments or suggestions will be greatly appreciated.

    Thanks!

    Ok. .157 plus -.066 is .091. So that's how far you'll be jumping....not .223"

    Remington 700's are notorious for having very long throats. If you want to have a bullet touching the lands then you'll have to single load. I'd suggest trying a different bullet and playing with the charges to get a better accuracy. Sierra Match Kings like to jump to the lands.

    Sorry if I worded things incorrectly but the bullet jump is .223. From zero, the mic measures the freebore tool to +.159 to the throat. In order for a bullet to clear the mag, the mic measures the loaded round to -.066 in the other direction from zero. The difference is .223

    Remington is known for there porno length chambers. I had the exact same gun and I could not get the bullet (175 SMK) to the lands even single loading. They were so far out that barely any bullet was in the case and I could literally pull the bullet out of the case by hand. As Ritten said try the SMK's as they tolerate jump. Shoot the hell out of the gun until you know it is holding you back then have the action trued and put a custom tube on it. PM Bayouslide for his Varget load. It is the same recipe that Terry told me to use.

    Edit: Before I started to roll my own the ammo I found that it shot the best with 155gr Hornady TAP which is loaded with AMAX bullets. The 1-12 twist seems to like the 150ish weight projectiles. Mine never did shoot the Lapua Scenar's well but I wasn't getting them up into the hypervelocity range that most who claim good accuracy with them do either.

    Yup, you're right. I get what you're saying now. It is normal for most 700's to have that much jump though.
