6.5 Grendel load data for 120gr Remington PSP Flat base bullet

[Tumbleweed58]

Hi all, I am new to this site but not new to reloading, I have been reloading for 40 + years. I recently built a 6.5 Grendel bolt action rifle, and was researching loads with powder and bullets I have on hand but the only bullets I have on hand are from Midway from a long time ago (around 30 years). They are Remington 120 gr PSP. they are a flat base, core loc style bullet with a cannelure around halfway up the bearing service. I am looking for load data as I have been unable find any at that bullet weight with a flat base.
Thanks,

Similar bullets would be 120gr Speer Hot Core and 120gr Sierra Pro Hunter. You will be fine using load data for 123gr bullets (most are boat tail) so you will need to adjust COAL. Ignore the location of cannelure on your bullets and determine your seating depth based on rifle chamber and powder charge/case fill.

Popular powders for bullet weight (115gr - 123gr) are 8208 XBR, H4895, AR Comp, CFE 223. There are any number of other powders that can work, including TAC, H335, and Benchmark.

Agree with Oso. I wouldn't have any issues substituting boat tail data with flat base, especially in a bolt gun. Most of the load data is for the AR platform. Oso already mentioned a lot of great powders to use. What powders do you have on hand or are planning to use?
