Speer 6.5 PRC Reloading Data???

[Vincent Vega]

Does anyone know if Speer provides any 6.5 PRC reloading data? Their website makes no mention of data for any of the PRC rounds:

Rifle Data

Speer Ammo

I've got a bunch of 140 gr Hot-Cor bullets that I'd like to use for my 6.5 PRC but can't find any data. Any insight would be appreciated. Thanks ODT.

Thanks. If I'm using 140 gr Speer Hot-Cors would it be reasonable to use an overlapping grain weight for a powder referenced in both? For example, the Nosler data shows a load for 140 gr bullets using 48.5 to 52.5 grs of 7828 whereas the Sierra data shows a load using 49.9 to 53.3 grs. If I start around 49 grs, I should be able develop a load using 7828. Does that seem reasonable?

Yes…..under most circumstances. The same weight and shape: Boat Tail, Flat base, ect. Most of the data from Sierra, Hornady, and Speer is general data for several bullets that they offer in the same weight or range of weight. It is derived for the most restrictive application of the given bullets in the listed bullets.

I believe that Mixed brass can, and often does, make as much difference regarding pressure as variations in bullet manufacturers for the same weight and type of bullet.

As a side note, you should load your first loads at a starting (light) load and work your way up to a higher load based on the observed pressure signs. You should, I should, we all should, but I usually start in the middle as long as the gun is modern and in good condition.

You should be careful using lead bullet data with FMJ or Boat Tail with FlatBase bullet data, and pay attention to weather or not you are reducing the internal case volume by seating deeper or stuffing a Boat Tail into a case loaded with a max load intended for a flat based bullet.
