147gr loads for a TS

[m1a_scoutguy]

Well just got back from a test run. I shot both my 07 & 01. Average for 10shots out of 07 was 897, with PF being 132. Out of my 01 average for 10 shots was 884 with PF being 130. 148 powder coated bullets are loaded in mixed brass with Tula primers and 3.2 grains of Universal & OAL is 1.125. Ran perfect with no issues at this time. Will load up a couple hundred and reconfirm everything and then have at it,LOL For sure out of my Shadow 2 and SP-01 Tac the average will go up and so will the PF,I could drop another .5 or so and see but would rather have reliability than a soft load that might not run in an awkward position.

Wobbly - Have not made a decision yet.  My last post was asking Painter for an opinion.

Painter the real number is 1.122 in.  To back this off a another 5 thousandths or so for safety would be 1.117.  Dillion usually gives +- .02 for seating. Will look a the stickies shortly. Thanks!

 Will also email VV and see what they have to say.  They seem to be a pretty cautious group and will probably be unhappy that I am using Speer and not Lapua Brass. (Even when stationed in Germany I never saw 9mm Lapua Brass.)  Never know they may have a ratio they use in making such adjustments.  Worst case is they will tell me to ream the barrel.

Leaning towards a split decision.  Send my TS barrel to Cajun Gun Works and retain the Tanfolio and experiment with dropping powder charges and shortening OAL.  My main concern with the dropping of powder and shortening is that it takes a certain amount of powder to push the bullet at the required speed.  Guess I need to read the stickies as Painter suggested.

Just tried BB RN 147s the best I got was 971 fps and the primers were pretty flat.  Surprised at how soft the load felt.  Backed off 2 tenths grain and that is what I will use for match on Sat.  Really accurate, extreme spread only 6 fps at 950 fps.   Only second bowling pin match so I will suck anyway.  These are still better loads than I shot the first match with and I ran third.

Thanks to all for suggestions!  Lots to think about.

Painter, thanks for the direction to look at the stickies.  Huge amount of information.  Lots of good posts from Wobbly with diagrams and graphs.  Great explanation for use of VV powders in 9mm (wish I had some VV N330 & N340).  So Mission Analysis is done time to select my course of action.  Will go both directions at once after the match.  Send the TS Barrel and have it reamed, then develop loads just for that firearm for this type of match.  While the barrel is out for a couple of weeks I will try some small experiments with my Tanfolio which has a slightly longer throat than the TS and see if reducing the charge and OAL can get me to Nirvana, (147 gr XTP OR Berry's HP to 1150 fps).  Cost is only $30 plus shipping and it greatly enhances the possibility of reaching my goal.  Also having a throat tailored for a load is great way to obtain greater accuracy.  They do it in precision rifle all the time.  Granted I only need to hit a 1 inch target at 10 yds which frankly is not that hard for pistols as well made as any of my CZs in this case I just have to hit it really hard.

Will post results when accomplished.  Sadly I am on the road for work for the next couple of weeks, so it may take a bit to see another post from me.

Thanks one and all.  JW

Just finished bowling pin match for the month.  Used the TS 9mm with the 147gr Berry's Plated RN and 6.5gr of VV 3N38 at 950 fps.  Only had two shots where I was positive of a good hit and the pin did not leave the table.  Rest of them were clearly my screw-up.  Result - Tied for second place.  Not bad for a second match.  Still feel the need for a little more power to eliminate those spinning pins on the second, third and forth shots that take up so much time.

WOW that's a HOT load.  I show VV  says 147 RN Heavy Plate, X-Treme Bullets  with N-320 has a max load of  3.7 grs.

SoCal.  Thanks for the catch the powder was 3N38 not N320.  Edited original.  JW
