200 gr bayou bullets and blue dot

[j32degrees]

Hi all, first post on the forum  but been lurking a while.   

I've been reloading about 10 yrs but just bought my first 10mm.   (g20)

I have already had good success with blue dot and 180 rainier plated bullets, but have bought some bayou bullets in 2000gr rn variety.   I have blue dot, enforcer and 231 on hand.    looking for something stout but not dangerous.   the searching I've done on the web shows 200gr with over 10gr of blue dot, but my manuals have very limited 10mm data and only show a charge of 8.9.

these are coated bullets and I'm using a 5.1" lone wolf barrel...  Especially interested in upper end ranges with blue dot and enforcer.

Thanks.   that helps a ton.

who offers some 200 gr hardcast with a flat point? TC or similar?  I'm doubting g20 will feed swc's.

any 200 gr lead projectiles you'd recommend for someone who doesn't cast their own.?  Bayou only has round nose in 200's

The round nose from them should be good and feed well, the only thing the SWC does is provide a clean hole on paper targets for scoring purposes.

The Speer 200 and 175 TC with a slight SWC line molded bullets are feeding fine in my G-29 and G-20 as loaded.

Cool.  So can those be purchased somewhere?   I believe you said you cast your own

You might want to try these guys out...Rim Rock Bullets  I think Underwood uses them.

Excellent.  Will give those a shot

Howdy Shadow.  I am about to order some of those Rimrock 200 gr TC bullets.  I have Power Pistol and AA#9 powder.  My friend and I will be shooting them out of factory gen 4 g29's.
Any special advice?  I do plan on trying Blue Dot someday as well some of the ill-metering super powders in the spring....like Longshot , 800X, and I saw a new one on Hodgedon's website,
with impressive numbers.  It was called CFE Pistol.
I always appreciate your advice.  You have made quite a study of the 10mm!

Be sure you inspect the Glock factory barrels when using cast bullets, deposits can build up fast if the bullets start leading the bore.  Bullet fit is essential 4015 or 4020", good lube also...

Accurate Arms shows the 205 gr Cast using a max charge of AA No.9 11.8grains @ 1157 fps 36,200 psi
With the Power Pistol 7.8 grains @ 1150 fps, but I have shot 8.0 grains under some of my 200gr cast 1180-1200 fps.

CFE Pistol works well with the lighter bullets but I haven't had a chance to test the heavier bullets with it.  *00x and LongShot have worked with the cast bullets as shown in the pull-downs...
Good luck to you and best regards!

Blue Bullets over Blue Dot in nickel cases. .40 cal and 10mm!

I just received the Rim Rock 200 gr TC and assembled a startingoad of 10.8 gr of AA9 seated to 1.26".   I'll see if it leads asap.

I tried a few loads with the Rim Rock 200 Grain Truncated Cone Bullets today (sized .401 15 BHN).  I shot 8-9 rounds each of ;10.8, 11, 11.2, 11.4, & 11.6 grains of AA#9.  These were done to see if my stock Gen 4 Glock 29 Barrel would play nice with them.  After the first few shots I saw some streaks...then re-checked every few rounds.  Forty something rounds later there was no changes and the loads progressively got warmer.  She is good to go.  Now I will have to load some more of the most accurate recipes and tweak further.  AA#9 is a fine powder that meters nice, smells good, and burns CLEAN.  I also have Power Pistol, but that will have to wait for another day. 

I was shooting standing off hand downhill into a big creek (15yds +/-) so I am sure each group would print tighter if the shooter was steadier.  I plan to load more of the 11.6 gr load and also up to the book max of 11.8 to see where it is the most accurate. I estimate that the 11.6-11.8 grains will get me 1000+ fps since the book says 1157 (5" test barrel).  It was a relief to see that I was getting no more leading through almost 50 rounds.  FWIW, the best I could measure with my mic showed me that the bullets were more like .402.  I don't know, but they work and work well in the factory barrel. Cheers!
