416 Rigby loads with Northfork CUP points, how hot is hot enough?

[Rule 303]

BC Tal thank you for that. Just from what Mooze was saying it appeared that a bullet was required to expand to a set percentage of it's size, this is what threw me.

How hot is hot enough....mmm....can't understand people who want to hot rod the rigby...stick with original velocity...it has worked for a long time.....I never had any complaints....and still pleasant to shoot....but do whatever you want....

You didn't mention solids you did mention the expansion size of the CUP and to check to see if a 1.2 times expansion was legal in Canadian Provence's. Like I asked where else other than Canada has a minimum expansion requirement. Until I read your post, I didn't know that an expansion size be it 1.2 or greater was a requirement in Canada. While we are on it how much expansion of a bullet is required in Canada?

Thanks BC-tal for the above explanation, nothing to disagree.
the original is here:

Hunting Regulation

there is no number, the 1.2 was my estimate for CUP point form change from pictures and the few I retrieved from the range sandbox (.366 286gr Cup points). I did not take pictures, idiot me.
I think factually the argument that it is NOT an expanding bullet will be difficult to make, as opposed to the Woodleigh hydrostatics the rim of the cup is so thin it is clearly made for deformation. But it certainly does not reach the 1.5x expansion of a Barnes.

 

[mooze]

so this is what NF writes, they clearly classify the CPS as an expanding bullet:
from their website:
The North Fork CPS performs like no other bullet you have ever experienced. The cup point expands up to 2/3 of caliber size, creates a wound-channel 3 to 5 times wider than caliber and penetrates like a typical solid.

So I think I am good for my upcoming DG hunt for Vancouver Island Blacktail....

No specific answer to your question, but I am considering using my 416 Rigby for a one gun safari. I am working up a load for 300 grain spitzers that should make a good plains game load to 200 yards or so. I must be pretty recoil sensitive because my 400 grainers at 2450 are intolerable, and I have loaded them down to about 2330.............JMO...........FWB

I used my 416 rem with 400 gr TSX on moose at 275 yards , dropped in his tracks for a one shot kill

I load my 416 Taylor to 2400 FPS using 400gr bullets. Thats about all the recoil I want, all the chamber pressure I want.. and seems to be more than enough to tackle anything walking the earth..

While Im sure 2500 FPS wouldn't hurt.. I don't see it as necessary.. therefore don't try to achieve it..

Why would Northfork do that? Canada is the only place I have heard of that requires a certain degree of expansion from any bullet.

actually several countries and candian provinces apparently do and one of them is Sweden where NF bullets come from.

this is from Joergen, CEO of Northfork:
Thank you for your message.
CPS is our expanding solid. It expands around 2/3 of the caliber diameter. We have same rules here in Sweden, we are not allowed to hunt with non expanding bullets and CPS classified as an expanding bullet.

Wound channel is 3-5 times larger than caliber.

I think you are on the yippy weed or a tad too much of the fine malt. Read the reply's on this page and you will see this is not only answered but explained. Or was this post of yours an accidental post?

I don’t think 2500 fps with the Rigby case size is “hot rodding” it. If it shoots well, is tolerable to you and is a mono metal projectile, go for it.
