300 blackout primers; to magnum or not to magnum

[ROLEXrifleman]

So which way are you guys going?

 

[straight-shooter]

I'm using IMR 4227 with standard Winchester primer with good success.

Various SPP, CCI & S&B, no issues. 4227, 1680, & Shooters World Blackout.

Anytime I use a double base ball powder I use magnum primers. This is because these powders have more deterrent coatings and a hotter and longer burning primer helps.

So which way are you guys going?

CCI small rifle. IMR 4227. So far I've only run 125 gr. Speer TNT so can't speak to the subs or larger projectiles, but the recipe has been flawless and powerful.

CCI SR and Wolf SR. H110 from the 1960s.

Blackout pistol maybe?

I have only used WSR with W296, vv110, a1680, and lil gun. I had never even thought about using a magnum primer, but now I am curious too.

I frequent the Outdoorsman and the last few times I've asked for small rifle primers, they've been out but have had Magnums. Considering finding a load I can use for plinking with them.

I load H110 and use both standard and magnum. No problems with either one

I am new to the group,but I have been using WSR primers with H110. Very good results. I have also tried CCI 450 magnums. I could not tell any difference.
