Importance of Primer Sealer

[MattStevens]

Does anybody use a primer sealer when loading hunting rounds? I have never used it, but noticed most factory ammo has it. I suppose it 's possible that my rounds might get wet from rain, or snow. I haven't had missfires due to a wet round, but was just wondering what all of you here on the forum think regarding primer sealer.

I have reloaded for over 30 years and have never needed any kind of sealer. I wouldn't be concerned about it.

I don't know if you need it or not but it can be handy in sorting out your loads. Use some red for the 140 gr Accubonds and green for the 160 gr Accubonds, etc. So if they get mixed up you can tell them apart. I can't think of any really good reason to use the stuff.

HEY MATT!
I took the test! Loaded/reloaded 6 cartridges (7mm rem. Mag. with 68 gr of H-1000 and 150 gr Nosler BT).
(2)New Brass
(2)1x Fired Brass
(2) 2xFired Brass
One cartridge from each group was treated with the Markron Custom Bullet and Primer Sealer. Next, all the cartridges were placed in a bottle of Poland Springs water for 30 days. Each day the bottle was inverted as to change the orientation of the shells. After 30 days the cartridges were removed from the water and dried off. I went to the range several hours later and here were the results…ALL SHELLS FIRED!
In fact, at 100 yards, my grouping was as tight as ever!
Does the sealer work? Not sure, but further testing might be warranted. I can't imagine hunting conditions that would be as extreme as this test. Could be a fluke? Hope this info helps!

Bruce,

I color code my ammo by bullet weight. After I clean my brass, I use #0000 steel wool on the case head. I use magic markers, Blue for Lt weight, Green for Mid weight and Red for heavy weight bullets. I color the inside of the primer pocket along the beveled edge. After the primer is seated, you have a color coded ring around the primer.
For any given caliber, I know at a quick glance, what bullet weight I am shooting.
You could also use this for different powders or charge weights.

It also gives your ammo a nice "custom" look.
