Tapa talk pics finally

Bullet

Pic of powder from pull down

Texashogman, Thanks for showing the Grizzly pull down you posted. 
Well, that bullet should be quite the thumper.  I see the bullet is gas checked but there is no lube in the grooves, of which the bottom groove is also the gas check base.  It hard to tell if they are using a PC (clear) but somehow I doubt that these are powder coated.  The bullet shows a medium crimp line where the taper crimp was applied.  Measuring the total cartridge and actual bullet lengths can show how much is inside the casing and how much is sticking out based on the total casing length.  This can also help if there is a feeding issue with these wide flat nose bullets with regard to tipping angles.

How much did the powder weigh?  It looks like Hodgdon LongShot, but total weight would help tell the story...
Is there a velocity shown on the box? or Have you recorded any velocity readings?

I posted info in the middle of the 1st page-- 8.5 grains of powder that looks like longshot , OAL is on average 1.250" --- no lube in grooves (and no it does not appear to be clear PC'ed)--bullet length was .640" long and measured .401" diameter in front of the crimp, after the bullet was pulled via a kinetic puller the diameter inside the case was .400" as the crimp was very tight

the box from Grizzly does NOT have a velocity on it and their website does not list this ammo, but sportsman's warehouse website does say it's rated at 1250 fps

I have not shot them yet, but they seem to feed just fine when chambering with the slide lock release--- it may be a few weeks before I get to shot any though, but I will report back after

I added the Grizzly 10mm 200Grain WFNGC cartridge into the Pull-Down documentations based on you findings  to preserve the history... 

Without any lube on the bullet, does that mean it will lead the barrel much more than normal? 

Personally I would prefer to have seen some lube or powder coating on them.  Lube can create some smoke, depending on the lube.  Powder coating is becoming a good choice for less fouling, however that are some coatings that have been causing barrel wear.
Depending on the fit of the gas check, it could clear out or smear leading in the bore, testing in a particular barrel will show one way or the other...

Thanks, I'll add the speed and accuracy data once I test them....i was disappointed when I pulled the bullet to find out  they have no lube in the lube grooves --- seems odd

what coatings are showing barrel wear??? I hadn't heard of this before

If I recall the black color was one of them with high calcite content.

QuoteHF black was known to be a relatively poor candidate for powder coating as it required the use of a sprayer gun to apply it... that brand and color in particular did not apply well at all through the tumbling method many hobbyist bullet casters use. Some folks did some digging and on the materials list for HF black (and no other color) they found a mild abrasive, calcite.

Another mention was PC with Barium Sulfate.

But Finding actual proof of barrel wear was a wash so far.  I also remember reading that some of these powdered paints have better scratch and chip resistance that others...

I would stay with solid color types if and when I start powder coating my own cast bullets.

WFNGC = Wide Flat Nose Gas Check?

Yes

Well, I tested them today--- too bad they are over pressure in my gun. I only shot 4 then gave up.
6" barrel showed 2 bullets at 1268fps, and 2 at 1289fps--- but check out the primers!!!

The 2 on the end (the 1289fps ones)seem to have just pierced the primer and the gold in the center I think is the anvil showing through the cup. I can hit 1430fps from a 180xtp with no.9 and the primers don't look anywhere near as bad as these grizzly primers do.  The other 2 are the 1268fps ones, not quite as bad but still over pressure for sure---- too close to the ragged edge for me.( edit, after removing the primers I found they are not pierced)

Also to note I had a .001" "belly" in the brass --- not good, not horrible but definitely not good.

They were really accurate too!!!

I shot 3 for a group at 10 yards--- came out as .5" center to center, then the 4th shot I adjusted slightly to see if I could hit the bull--- really accurate ammo, but too over the edge for my comfort level .

Those primers don't look too bad to me.

Can you show a side pic of the brass swelling?

Try this picture....sure looks like the primers gold colored anvil sticking up through the siler colored cup to me--- I've never seen a primer do this before....ive had pierced primers in rifles before but never in pistol.
I'll go pop the primer out of one to see it better and see if I can confirm if it's pierced or not. ( after removal I found the primers have not been pierced)

The edges of the primer are still kinda round, and you can't see the "belly" with the naked eye--only by using calipers --- but Those primers scare me
