For those of you who have the TS370, what velocity are you getting from it?

I chronographed mine today with 400 gr. arrows and was getting a consistent 359 FPS. I’m content with that, as it’s close to the advertised speed with an arrow that’s 20 gr. heavier than the arrow used for the published velocity.

Just curious to know what the rest of the 370 shooters are seeing.

Add 2 twists to the single end cables and you will gain fps. I had mine shooting 400 gn. 378fps. I have around 900 shots on strings and cables and have slowed down to 360 fps. Need new ones.

Overall, I think that is outstanding performance after 900 shots, shooting 360fps. Mine out of the box with the addition of shims and no cam advancement shoots 369-370fps with a 400grain arrow after 75 plus shots. I suspect over time I will follow your path. There is a diminishing return over a period time with strings and cables. 378fps is quite impressive for such a small crossbow cam design. Wow!

Let me add a bit more depth. Add shims, see my TS370 riser modification post. That may help you gain some FPS also, adding twist like HunterThompson will definitely help. Also check your ATA uncocked. It should measure 16.75 inches post to post.

Good luck, Clarvis.

If you shot a 380 grain arrow-point combination, you would gain approximately 6 feet per second which would put that crossbow at 359 + 6 = 365 feet per second. For every 10 grains over what the manufacture advertised to get their speed, one loses approximately 3 feet per second. 20 divide by 10 = 2 x 3 = 6.

All the best.

Also those are not stock strings and cables. Built with x99 and halo servings. A good set of customs when the stock wear out should show some gain. Had 3 extra twists in the cables. Added 1 a week for 3 weeks to get the 378fps.

my TS370 shot 352 FPS with a 448 grain bolt.

So 367 with 400 gn. Nice

i loved my ts370 - one of the most under rated xbows on the market. i have/had a few xbows to compare it to first hand, one of my favorites

 

[Huntersthompson]

From my fingers to barnetts ears: build a ts420. Use the 370 platform with heavier limbs and bigger cams. No step thru riser,just like the 370 and people will eat them up.

Christopher, Maybe not as many Xbows as yours but I've gone through a few and totally agree. So underrated. Whoever at Barnett engineered this Xbow got this one right. A+ is the grade I'd give this Xbow.

Got that right.

Barnett, I hope you are reading this. Put some aggressive cams on this setup, beef up the limbs if need be but don't do a darn thing different, maybe add a Barnett shim kit to reduce downward bow string tension and you got a major seller. Don't get sucked in the ultra narrow cosmetic energy. It's an overplay for this price segment in the market. Truth be told the TS370 is quite narrow at 12", cocked ATA.

Thanks for the tips gents. I have one weekend left in OK's archery season and I'm going to try to get it sighted in so that I can go out. All I really need to do is confirm my scope settings and where the arrow impacts at each crosshair using a practice head and I should be G2G. The riser shims will have to wait.

I'll check the ATA this evening, but since adding extra twists to the cables or string takes a bow press, that will have to wait until later. As it stands, the cams are level and correctly timed.

This is my first crossbow, but I'm really pleased so far.

Go put meat in the freezer. You are set with that setup, CJ!

Good luck and good hunting!

Twists to string will slow it down. I would read bunny rabbits tutorial before you attempt it when your ready......360 fps blew right thru deer I shot month ago at 30 yards. Good hunting, Brother.

 

[CJarvis]

HST, where is that tutorial if you please?

 

[Huntersthompson]

Click on barnett crossbow,go to bottom of page. 370 strings ,to twist or not to twist. Click on it. Read thru all,you will see B Rabbits posts. If you have questions ,pm him. Man is a wealth of barnett and tuning in general knowledge. He may read this and respond. He often does. He is getting incredible speeds from his tuned up barnetts.

 

[CJarvis]

Thanks.

Finally got ‘round to measuring the ATA. 16.75” exactly and the axles are equidistant from the center of the rail.
