Because of the speed I was getting out my rifle many thought I was over pressure. . Here are the results ![[Linked Image from i.postimg.cc]](https://i.postimg.cc/CMnYq85z/35-Whelen-Pressure-Data-X3.jpg) I just noticed a typo error on the pressure chart, the 250 grain Hornady was loaded with CFE223 not Power Pro Varmint

Great info showing the actual pressure with the performance we're seeing in the Whelen with the newer powders!

Good to actually know. Stout performance!

Can you explain how you are measuring your pressures please? I'm truly interested. What kind of investment do you have to generate that data?
They say everything happens for a reason.
For me that reason is usually because I've made some bad decisions that I need to pay for.

A friend with an Olher strain Guage system did the testing for me. He used a Remington M700 with 22" barrel.

Oddly I really like the old Whelen pushing a 250 grain bullet at 2450 fps. I can imagine recoil becoming an issue with the faster loads.

Very useful, thanks. Especially the 250 Hornady with CFE 223. I guess what they say about that and MR-2000 getting lower pressure is really true. I always got scared of the velocity in MR-2000 even though I wasn't seeing pressure signs.

Great information and much appreciated that you took the time to share it. Thank you. 👍
So I must’ve missed it (not unusual) but I assume Power Pro Varmint and MR2000 are the “same” powder?
