View Full Version : Velocities with 95 TTSX

I ran some loads across the chronograph yesterday and came up with the following numbers:

29.2 gr of 10X = 2610 fps

30.0 gr of 2200 = 2870 fps

95 TTSX, SSA brass, cci 450 for both loads

18" PSA spc II barrel

Just looking at the velocities, the 2200 is great. Unfortunately, the 2200 didn't shoot very well (over 1.5"). On the other hand, the 10X delivered .4" - .6" three shot groups at 100 yards.

For any of you shooting the 95 TTSX, are those results (velocities) within the norm? What loads work for you and at what velocities?

The AA2200 load looks just right, but the Re 10X load is way low, presuming that is not a typo. 29.2 grains should give you just about 2800 FPS or a little more from an 18" barrel.

I personally use 30 grains of AA2200 and get groups of 1 to 1.25" at 100 yards, with velocity of around 2830 FPS from a 16" barrel. My OAL is 2.290".

I also liked 29.5 grains of Re 10X before AA 2200 came out, but its compressed more and is extruded whereas the AA2200 is ball so is not compressed as much, at similar powder charge.

I agree 2610 is a little slow.What is your COAL?Also, how many rounds have you fired (total) out of the barrel?

There were no typos in my post. The 2610 fps surprised me. I was expecting a higher velocity. Since I fired that load first, I just thought I had a slow barrel, but the 2200 velocity shows otherwise. I will try the 10X load again to see if I somehow mis-recorded the data. The only thing I can think of would be a lower charge weight, perhaps 28.2 gr, but I don't know how that would have happened. I am not new to this.

COL - 2.295"

The barrel now has a wopping 30 rounds on it.

My 2200 load was a fairly large group as well until I started adjusting by .1 increments and it just suddenly closed up. I'll post my load (which is really hot) once I have my book in front of me.

16" ARP 1:11.25" twist BBL. Chron'ed at 2900 fps. @ 100yds. Repeated load came in at 2904 fps, and .30" 3 shot group. Accurate load.

Shot the 95 TTSXs again today. I bumped the 10X load to 29.5 gr and reduced the 2200 load to 29.5 gr. the results were:10X - 2675 fps - .246" @ 100 yds2200 - 2810 fps - 1.5" @ 100 ydsAlso learned that the gun doesn't like 110 ABs over 2200 either. I am really looking for 2800 fps for the 95 TTSX, but the accuracy of the 10X makes it the clear winner even at the slower speed. Comments?Dan

IMO ------> accuracy is better than speed. You can compensate very easily for lack of speed/trajectory with your scope adjustments. The 95gr TTSX slower speed will allow it to penetrate further and not open as fast. But at the speeds that you published it will open adequately and "fast enough".

I had a 220Swift that would shoot a 52gr into the .3's at 100yds. This load "only" produced 3700fps. I killed many coyote's in the 55lb range with that gun. The load would produce instant kills and would allow me to take shots out to 500yds or so. Same with your situation. The accurate load is slow but in no way anemic.

Good Shootin' --- pruhdlr

I agree 10X looks better for accuracy. I would load 2200 if it was my gun as I want the velocity advantage for hunting. Accuracy of 1 1/2" @ 100yds will kill deer and pigs. I would continue to fine tune the 2200 loads (powder charge, COL, etc) or different bullets. my 2 cents as hunting is my main priority.

I just chrono-ed some rounds on Friday using these very components. The AA2200 works very good through my rifle. It showed very high velocities while maintaining its accuracy.

29.5 gn x AA2200 = 2785 1.5" groups
30.0 gn x AA2200 = 2843 Less than 1" groups BEST

OAL = 2.285 with a little roll crimp

Again, that is my rifle's favorite recipe!

I'm getting 2730 fps with 30.0gr Rl-10 in a 16" barrel with the 95gr TTSX. Well under moa accuracy.

I am a competitive shooter and typically, I will take accuracy over velocity every time. For hunting, however, there are certain issues that paper punching does not have, namely the performance parameters for the bullet. Barnes indicated to me that you need an impact velocity of 1800 fps or more to get bullet upset of greater than caliber. Also, I would prefer to keep impact energy greater than 1000 lbs/ft for deer. With a muzzle velocity of 2675fps things begin to get a bit marginal in my opinion when you get beyond 200 yards. Therefore, I would like to get an extra 100 - 150 fps.

From an accuracy standpoint, I do not require one hole groups or even sub 1/2 MOA groups, but when they get over 1 MOA, they start to look like a pattern rather than a group to me. I know that 1.5 MOA for a short range (under 300 yards) deer/pig rifle is more than adequate, but I do like those itty bitty groups.

I am thinking about backing the 2200 load down 1/2 gr in 2 increments, and maybe trying some different primers (I have wolf SRM, Fed. 205M and Rem. 7.5s on hand). Any suggestions would be appreciated. Even 29.0 gr 2200 should yield @ 2750 fps so it would be a noticable, but not terribly significant increase in velocity.

My 6.8SPC is a 18.6" barrel spec 11 chamber 1-11" twist Robinson Arms XCR-L my loads are Rem LR primer brass, Win LR primers, 30grs H322 crimped with a Lee factory crimp die COL = 2.29" gives me an average of 2825fps.

The Barnes 95 TTSX can open at speeds as low as 1600 FPS. If you can shoot that 10X load into 1/2 MOA, then that's a winner. If you know your likely ranges, then you can calculate the distance to which the bullet will function.

I shoot the 30 gr AA2200 load out of a 12" SBR and the velocity is lower than what you see posted with 16" barrels, obviously. That didn't matter when I shot this hog at 300 yards, at night, using a 4X D-740 Gen 3. It was DRT, and I think the bullet would have been going around 1800 FPS when it hit. Exceptional accuracy made this kill possible at that distance.

2575 5 shot average - 27 grains H4198 - 10.5" Noveske - I don't have the exact O.A.L. handy but it's loaded to fit in a Barrett magazine.
