10MM Velocity Comparison-(3) Guns- 4 different barrel .

LOL, I just came from there.

Lookin good!

I see you got that 11.5gr AA7 load right at a nice Norma spec level from your G20SF (4.6" barrel), hitting 1205.  Did you use a Magnum LP primer in that one?

I think right around 14.0gr of AA9 should do about equal.  At 14.0gr of AA9 I had a hard time getting any lower than 1.263" (COL) without crushing an XTP nose.  That's okay though since Glock magazines handle 1.263".  I've been meaning to try it while seating and crimping separately, just haven't got that far yet.

Gun is the Kimber Target II-5" barrel. Brass is Starline. Primers - WLP, ALL loads were weighed out ona a digital RCBS scale.

Never realized yet that the Nosler looks to have a possible anti-frictional advantage over the Hornady offering.

Are the above numbers averages, or did you limit them to a single round per recipe?

I'll definitely be looking forward to the results of the next batch.

Well done sir, and thanks for sharing!

 3 shot average.
I was a little suprised by the difference in velocity.

Me too.  I'll be curious to see if it continues (I expect it will), and to what extent.  I'm almost thinking as pressures rise further the differences may grow further too.  I have no clue though.  I am excited to see the next batch of numbers.  Happy to see you were doing 3 shot groups of each, making me feel better that the results are relatively consistent.

Thanks for you chrony reports, I too am taken back by the higher numbers using less powder.  Your batch of powder maybe a faster burning lot or produces higher gas volumes...   I would also bet that the chamber of your Kimber II is quite a good fit...Have you measured your brass as fired in the chambers?  I suspect the brass to be 0.4260"-0.4280".

Most of the Nosler bullets I have measure were slightly smaller in diameter as compared to the Hornady products, thus less friction.  Maybe slightly less accurate as well.  Examples have shown them to be 0.3995" for the 10mm/40Cal in some of the pulldowns.

[475/480]

Good question , I will measure a few .

Now looking at your latest test numbers I thinking there isn't a velocity/pressure difference between the 200 grain Hornady and Nolser bullet loads.  Sure, minor differences can be seen, but now those differences go both ways.  Good stuff, thanks for sharing.  Will there be a next batch?

BTW, at 10.6gr you've got that 150 Nosler moving along quite nicely.  The 9.3gr for the 180 Nosler matches the Buffalo Bore 180gr load perfectly.

3 shot average.

I will run a few thru my STI 10MM - 6" barrel.

That will be cool to compare.

I thought these were going to be Speer 165gr GD but NO, kinda suggests I have too many orders coming
I will increase the loads a little this weekend,probably all powders except the AA9 loads.

Interesting dead zone with 15-15.5 grains of #9.  Then at 16.0gr it wakes up nicely.

Do you recall if those were beginning to be compressed yet?  If so, would you call the compression light, moderate, heavy, maxed out?  If powder can still fit, it might be interesting to see the results of 16.5gr.
