Do you guys w/ long throated rifles chase the lands when seating?





When I reload for my rifles I try to seat almost touching the lands but, on deep throated rifles I have just seated to normal specs. I was wondering if you guys try to get close on these deep throated rifles and does it give you better performance?



It seems on some rifles you almost have to just barely seat the bullet to get that close but, I have always heard "get it at least as deep as it is wide(dia.).



Thanks

my understanding (through reading, not from experience) is that if you CRIMP a bullet, then you provide a uniform start pressure, which is pretty much the same idea with seating near the lands. for a rifle with a long throat, crimping might be the solution to consistency, which leads to better accuracy. the only other solution i could think of would be to simply seat out as far as the magazinie allows.

I went through this with my Whelen. Tried to "seat as long as the magazine will allow". The resulting spread in velocity was a jaw dropper: well over 100 fps.

On the advice of the gentleman at Sierra, I seated the bullet another .2" deeper. Accuracy stayed the same (based on 5-3 shot group averages), velocity spread dropped to 30 fps. Velocity stayed the same. FWIW, Dutch.

Reloader, that is an excellent question. Thanks for posting, all...sakofan..I have struggled with that myself.

One other reason for loading close to the lands is that the bullet is less likely to enter the lands crooked and get distorted. Some rifles have long leades and also have wide fat ones, so there is ample space for the bullet to yaw before it hits.

At least that is what I have read, all of my rifles, except one, I can load close to the lands.
