These bullets are almost as long as a 69 grain bullet, should I use the data for 69 grain bullet or 63 grain bullet at hodgdon's online data center? I'm using IMR4895, the max for the 69 grain is 24.8, the 63 grain, 25.3.

I'm safe either way, as I've loaded them with 24.4 grains.:) These are for a mini-14, FYI.

Speer claims their 62gr FMJ-BT is a clone of the bullet in the M855 cartridge. Their data shows 22.5-24.5gr of IMR4895 with a CCI-400 primer @2.255" COL when useing this bullet.

Seems the load data doesn't agree across the board, if I see pressure signs, I'll back it down to 24 grains for the next batch.

Load data usually wont agree across the board. There will always be differences between each persons/companies testing. Just use common sense. I also use the Speer 62gr data to base my test loads off of.
