.223 reloading question

[Blood Trail]

I wanna reload .223 70 grs Barnes TSX with 26 grs of BL-C(2).

The Barnes load data list max load for this bullet and powder to be 24.5 grs of BL-C(2).

The bottle of BL-C(2) list 26.5 grs for a Spr SP.

Does it matter the bullet type or is it all about weight?

[wsteffen]

yes. Different bullets engage the lands sooner and cause higher pressures. You need to look at the data for the particular bullet that you are loading for. I didn't say this, but from past experience shooting hand gun silhouette, if you are careful and know the signs to look for, you can exceed the manuals load data. Must know the signs of over pressure though.

The type matters. Some bullets have a longer bearing surface. It's best to use the data for the bullet used in manual.

[JakeGraves]

Start around 23gr and work up. If not pressure signs at 26, then yes you can.

[wsteffen]

Pressure signs, hard extraction, primer surface following out around the indent from the firing pin, split cases. Google over pressure signs so you know what to look for.

Barnes also say up to 100k jump, you can call them needed good customer service for me.

Here you go from Barnes manual. .

Some people will interchange load date for similarly constructed bullets of the same weight. I don't. Reloading is a business where thousandths of an inch matter. A .224 caliber cup and core bullet from Speer isn't exactly the same as a .224 caliber cup and core bullet from Hornady. You absolutely should not do it with monometal bullets. There's waaaay too much difference in the construction of the bullet to use any cup and core data with monometal bullets.

Looks like the 26 grs is way over pressure according to Quick Load. Thanks guys.

[LWD]

And why would you want to use other data when you have manufacturer and bullet specific data?

Can you even get 26g into a .223 case?

I'm loading 27 into LC cases. It's to the mouth. Varget

[Blood Trail]

I know sometimes companies list max loads a couple percent under.

I reload more shotgun (shot, slugs, buck) than anything. Weight matters most when reloading so you can interchange weight of payload. There's only a few exceptions. For example, 1 oz of shot will have a higher pressure than 1 oz slug.

I was thinking maybe rifle reloading operated the same way.

You'll achieve the 1800 fps minimal expansion speed for the Barnes. No need to make a hot load. Just build an accurate one.

Generally, no. However, when shooting copper only bullets, it can matter.
