35 Whelen QL request

[Jimbeaux82]

Would one of our erstwhile members please run a QL for 35 Whelen, Hornady cases, 180 gr Barnes TTSX, cci 200, IMR 4064, 24" barrel?

Also, does anyone have experience with the 180 gr TTSX for deer in 35 Whelen and how did it perform?

TIA

Jimbeaux

[Jimbeaux82]

Dr Mike,

as always you are on the ball. I would think that the TTSX with its "bands" might develop a little less pressure with powder charge due to less contact area than the original "x" bullets referenced.

Thanks

Apologies are in order. I was rushing since I'm playing nurse for a few months. That's what happens when you wife decides to jump off the roof (don't ask). Here's the correct data.

I have tried the 200gr TTSX in the 35 Whelen / AI and it didn't do anything special for me as far as accuracy and I did see increased pressure.
I had better luck with the 200gr AB and 225gr PT and don't think you could go wrong using either of these 2 bullets unless you can only use mono bullets where you live.
Also if your rifle is a modern version you should be able to load to a little higher pressures and see an added advantage with it. Nosler list the 200gr AB loaded to 3000fps in their E-manual.
The 225gr PT at 2950fps is a sledge hammer.

 

[Jimbeaux82]

Dr Mike,

can you explain why the TTSX must be loaded "lighter" than the original X? I thought the contact bands were to reduce bore contact and friction?

[DrMike]

It is precisely because it has less bearing surface that it requires less propellant to drive it to what is essentially an identical velocity/(max chamber pressure). You could increase charge weight, but you will also increase pressure and gain a rather insignificant velocity boost.

 

[Jimbeaux82]

Dang - that is opposite of what I thought!

 

[SJB358]

Jim, I'm using the 180 TTSX in my 350 Rem Mag around 2850'ish I believe. It only has a 18" barrel but oh my darn is that bullet accurate in that rifle.

I think you'd have a real stomper in a Whelen.

 

[DrMike]

I use the 200 grain TSX in my 350 RM. It leaves the muzzle at ~2750 fps with a stiff charge of TAC. Quite an accurate round.
