Is this 300 RUM load on the slow side?

I'm shooting the 200gr Barnes LRX bullet with RL25 in my 300 RUM with a Barnes manual max load of 88 grains. The Hornady manual shows the 220gr bullet with 92.5gr as a max load.

I have no chronograph as of yet, but here soon in the spring. Am I on the slow side with 88gr?

Barnes have always created higher pressures in my rifles. Like everyone always says...don't ignore what the manuals say.

That's on the high side. Estimate 59k psi and 3200fps if a 26" barrel.

IIWM I'd get a chronograph sooner rather than later.

That Manuals max is probably max.

If it shows no pressure signs and is the best shooting then fine but I believe you will find accuracy lower.
