Of course every gun will be a little different but was wondering what the over all consensus was on max OAL that you found for your gun. I’m not set up just yet for reloading so I can’t do the testing. My father is the family’s reloader but that’s about to change. And also, have you found it better or worse to load closer to the lands?

all depends on the bullet

......yeah...I guess ya got me there...Just goes to show how well I know my way around a reloading bench.

A 275gr Barnes touches the lands in my guns at around 2.465ish. I seat them 2.410ish.

Barnes Technician told me that Barnes bullet like a "little jump" to the lands. They recommend 0.05-0.070 jump. When I measured my distance to lands on my Ruger No.1, Gunsite Scout, and Hawkeye 450s, all measure between 2.465-2.470". Like Al I load the rounds to 2.410" That is using the
275 XPB.

found a couple of other notes this morning on OAL in my 16" Bushey barrel. I'll double check with my bolt gun and #1 when I get a chance.

The 450 has a very generous .200 of freebore according to SAAMI specs, allows some bullets to be seated farther out like the 275gr Barnes for some added case capacity

300gr XTP mag 2.220 to the lands

250gr FTX was 2.460 to the lands (not much bullet in case)

300gr Speer deep curl 2.225 to the lands
