My 35 Whelen Loads Pressure Test Results

Many felt that my loads were over pressure, so I had them pressure tested. Here are the results.

It would be interesting to test the speer load of CFE223 and the 250gn hotcore and the sierra 225gn spbtgk load for pressure.

I had my Ruger No.1-S with 24 inch bbl out today. Shooting 225 gr Sierra's with CFE223 from 63-67 grs. Grouping was not great, but two loads did best: 65 and 67 grs at around one MOA. While the loads will definitely get anyone's attention, I did not see any obvious signs of over pressure.

I just got it back from Ruger for service because on two occasions I had misfires, light strikes.

Got back a note underlining in bold RED that GREASE needs to be kept to minimum in the action, LOL
I suspected that may have been the issue but I didnt want to start digging around in the innards of the receiver, buggering screws etc. Besides I bought it used so probably good to let them have a look.

They sent back a test target too, which I have never known them to do, I didnt complain of its accuracy.
Test target showed 3 shots of Rem 250 Spitzer at 50 yards in the same hole! I have used that same load at the range and it is a good one.

Ses don't keep us in suspenders mate, what is the load and velocity.

I just noticed a typo error on the pressure chart, the 250 grain Hornady was loaded with CFE223 not Power Pro Varmint

@jwp475
Ifn that was the 250gr roundnose, I noticed I had to increase the charge to get 2,680fps. This was because of the much smaller bearing surface. Still easy bolt lift and rounded primers.

Your pressure chart appears to be well done, and reflects reasonable
velocities against barrel length and bullet weights.
I tend to think that pressures vary as to chamber and barrel specs,
along with loading variables.

Every rifle is individual as to pressures and performance.

My 35 Whelen is a custom pre-64 Model 70 that utilizes the original barrel
that was cut-rifled, re-bored , along with re-chambering. Its accuracy reflects the quality of work that was done by the riflesmith. It has a Super Grade-styled stock. Best work is reflected with 225 gr Nosler partition bullets.
But it was designed as a big game rifle that could be safely used in bear country.

Dont know the speeds on them. I have a little barrel type chrono coming so may be able to start getting some info soon on that and other rifles.

You're getting about the same velocity as my .338WM and I feel supremely confident carrying my .338 - so you should too!
It never ceases to amaze me just how efficient the '06 case really is.
I reckon you're all set for almost anything

I will have to bring my Whelen down for you to try on sambar we it 250gr Hornady round nose a 2,700fps.
That puts some serious hurt on things

@Bob Nelson 35Whelen ,

I have absolutely no doubt it will mate. I have personally used the 225gn Woodleigh PP in my .338 at a mild 2750fps on Sambar and that was effective

Russ or I could bring my 25 for fallow or red and we could discuss the merits of a fast 25 over the 243 and 6.5 manbun over a few rums.
