The hornady loading data is for the WSR primers, how would you vary the load for the large rifle primers used in the wolf brass? or can you not?

[bwaites]

I would start 1 grain lower and work up. The load differences between small magnum primer Lapua/Hornady and large primer Wolf is minimal, with the caveat being that the Wolf brass will not hold up as well and the primer pockets will loosen within 5-6 rounds max, or even earlier, at least in my experience.

I looked up the WSR primers just to double check and they arent magnums they are just normal small rifle.

So what is the difference between a small rifle and a large rifle primer? Id really like to be able to use the 95gr vmax and the 120gr hornady amax. The problem is that in the hornady book for the grendel, its only published w/ the WSR primer data.

The outside diameter is different.

[Raider1v1]

The outside diameter is different.

Sorry, let me be clearer. I am looking for the amount you need to vary the load data to accommodate for the extra power of the large rifle primer vs the small rifle primer.

Completely different brass. LRP can't be used in SRP brass, and vice versa. It's just not possible due to the size difference of the primers.

If you're asking about regular SRP versus magnum SRP, adjust load down by ~0.5gr for magnum primers to be used with data for regular primers. Magnum primers are hotter, and usually generate higher pressure and velocity.

This is just my opinion based on experience with a different cartridge, so use at your own risk.

And if I'm off base and LRP Grendel brass exists that I'm unaware of, I apologize.

As a general rule, you don't have to worry to about it much, rifle primers are rifle primers, large = small except for size. Magnum = Magnum. Drop down a grain or two and work back up, I'm ultraconservative and world say drop down 10% and work up.

Drifter,

Wolf for some reason still uses LRP in their Grendel loads.

bwaites,

There is a difference in the large rifle/small rifle large pistol/small pistol primers. There is very small, and they are considered to be interchangeable by some, but others warn to never do it... Here is the info that I have from another forum:

NOTE: This data is reference only. This is on a DMS (don't mean squat) scale. It is relative to this set of tests and this tester. Take them with a grain of salt and as a guide only. Most of the tests were of 100 or more primers. A few were of 50 when limited amounts were available.

Ranked in order of power

Questions -

Does anyone have the most recent Sierra manual and can they confirm that there's Grendel data in it?

Does anyone know of more factory reloading resources?

[GregP42]

JA,

The latest Sierra I have is Edition V and it does not have any Grendel info in it.

[JASmith]

Thanks GregP42!

[LRRPF52]

That's cool that Ramshot published 20" Grendel data, but with 1/10" twist?

What barrel maker even offers 1/10 twist in a .264?

They do http://bartleinbarrels.com/calibers.htm with a 100$ extra

I have 10 boxes of assorted AA factory ammo. My chamber has been throated long due to it being a single shot rifle. Can I pull the bullets and adjust the length for better accuracy? I use a Hornady collet puller.

Thanks, Dinny

While I've been reloading for a while, I'm still not sure about the performance differences between regular and magnum primers. For instance, many loading charts suggest using small rifle magnum primers for loading 6.5 ammo. But what are the performance consequences. Also, would this same difference (if any) apply to things like using regular small pistol primers for loading 357 magnum rounds?
