Description
Starline has been turning out some of the most respected cartridge brass in the country for decades, and this .260 Remington offering is a great example of why handloaders keep coming back. These are new, unprimed cases built for the 6.5-08 crowd who want a consistent starting point for load development. If you shoot a short-action 6.5mm and reload your own, this is brass worth building a load around.
The .260 Remington came out of the wildcat world and was commercialized by Remington in 1997. It runs a 6.5mm (.264") bullet on a necked-down .308 Winchester parent case, which means you get those high-BC 6.5 projectiles with noticeably less recoil than the .308 and a flatter trajectory. That combination is why the round has carved out a home in bench rest, metallic silhouette, long range competition, and the deer woods. It uses a large rifle primer and feeds nicely from a short action.
What Sets Starline .260 Remington Brass Apart
Starline starts with an alloy of 70 percent copper and 30 percent zinc, then vertically draws the cases rather than using the more common horizontal draw. That approach keeps wall thickness variation to a minimum, which translates to more uniform case necks and better consistency down the line. Cases are annealed between each draw for consistent metallurgy across lots, and every case passes through hand inspection along with final machine checks for flash hole presence, correct length, and diameter.
Prepping Your Starline .260 Rem Cases
This is bulk, unprimed brass, so plan on a little prep before loading. Run each case through a full-length sizing die (or at least let the expander ball true up the neck), then trim, chamfer, and deburr the mouths. You may spot a faint stain on the necks from the annealing process, which is purely cosmetic and tumbles right off. Cases measure 2.023" to 2.028" out of the bag. Do that groundwork once and this brass rewards you with the kind of repeatable performance that makes chasing small groups a lot more fun.

Frequently Asked Questions
Are these Starline .260 Remington cases primed or loaded?
No, these are new, unprimed brass cases only. This is not loaded ammunition, so there is no primer, powder, or bullet installed. You supply your own components and load them to your preferred recipe.
Do I need to prep this .260 Rem brass before loading?
Yes, as with any bulk rifle brass you should do a bit of prep first. Full-length size the cases (or run the expander ball through the necks) to true up any mouths that settled slightly out of round, then trim, chamfer, and deburr. A light anneal stain on the neck is normal and tumbles right off.
What primer size does the .260 Remington use?
The .260 Remington uses a large rifle primer. These Starline cases are drilled with large rifle primer pockets, so load your large rifle primers of choice.
Can I form this brass from .308 Winchester instead?
The .260 Remington is based on a necked-down .308 Winchester case, so some handloaders do form their own. That said, starting with purpose-made .260 Rem brass like Starline saves you the forming, trimming, and headache, and gives you cases already held to the right dimensions.
