The 22 creedmoor thread

[Castle Rock]

Yep, the 6.5 just kills quicker
Over the last 10 years I have mostly hunted with a fast twist 22/250 and heavy bullets and 6.5 CM and 260 AI
Despite all the photos, gel tests etc there is no doubt that the larger caliber puts down animals quicker and with more authority
I am going to retire my tikka 1 in 8 22/250 because there are just too many instances where a good shot didn’t anchor like a larger gun does

Ah well I have just made a liar of myself
Killed a very average pig with a very average shot yesterday
I just love this rifle and scope so much that I grab it every time
I have run out of TMKs so am going to use 80 ELDMs at 3185 for a while

Anyone have any experience on big game with the 77 TMK Launched at 3100+ FPS out of the 22 creed? I have settled on a load with H4350 that is giving me on average 3150-3160 FPS at the muzzle of my rifle. I am dead set on using it for mulies and antelope (if I draw this year) - possibly elk - still debating.

My thought was that bullet at that speed - try to be more lungs and less shoulder if a sub 100 yard shot comes up...???

I am also set on using 77tmk in my 22 creedmoor vandal x for North Carolina deer..

I keep thinking about trying the tmk just for the terminal performance but it seems to really fall behind an 88 eldm in other categories

I’d keep it off the shoulder only for the reason that you’re going to completely destroy it.

Given this I will aim even off the crease into the lungs. Last deer I put a 77tmk within an inch of the shoulder starting at 3k pretty must destroyed the entire entrance side shoulder.

I would have no reservations putting that bullet in the shoulder, mine are starting at 3k.

A combination of old school and new school and now I’m part of the crowd.

I had the barrel taken off my .358 Win and replaced with an 18” 1-7 twist barrel chambered in 22 CM. I wasn’t using the .358 because the recoil was fairly brutal and it didn’t kill anything faster than the .223 did.

The stock is made and checkered by me, modelled off classic old English stalking rifles. Very different shape to the modern way of thinking, but I love it just the same. I’ll probably end up building something like a Rokstock for one of my Tikkas at some point- in a nice piece of walnut of course.

Off to the range tomorrow to try it out with some 88gr ELD-Ms.

What's the barrel breed? Interested to see how you get on with blowing up elds in that twist with the barrels we have available in NZ.

It’s a Hardy barrel. Despite some bad press from the past, I’m really happy with the product and service.
The 88’s will be doing 300.8k rpm so should be fine.

PBB 20” 7 twist, Peterson brass, Fed 210, 88 eldm, Staball 6.5. Haven’t seen much info on Staball for the 22cm but it gave great speed with zero pressure signs on the brass, primer, or bolt lift at 41.5-42.5. Going to load 15 at 41.5 and go shoot a group.

I had better speeds from StaBall match than I did 6.5 before i hit pressure. Idk how it'd do with 88s but 4350 an Varget are pretty hard to beat imo

That is making my 18” factory tikka barrel look unbelievably slow. 40 grains of 4350 and I was getting pretty heavy bolt lift

Try one of the other h4350 burn rate powders. I get good results from n555, sounds like Staball might be good too. Something a touch slower burning than h4350

 

[prcwv]

That new Ramshot Grand might do well with it they got load data for it. Pretty cheap at the moment. It reminds you of StaBall powders fine as heck

I had very slight pressure signs at 40 grains of H4350 at an average of 3060fps. I’ll revisit H4350 if Staball doesn’t do what I want but right now it’s showing better promise in this barrel.

That has my attention with the staball 40 grains felt like the bolt lift was heavy but 38.8 is shooting very well at 3050 in my gun I’m on the fence if I want to mess with it or just roll with what I have since I have more than enough 4350 to finish this barrel off

If I remember right I ran up to 42.5 in virgin Alpha SRP with cci 450s. An got 3400 with a 22 inch barrel 1in 8 75eldm. I'm not running 39.2 Varget averaging 3490 with 75s

apologies if the question has already been answered, but…


I’ve created quite the pile of “once-fired” 6cm brass. Is this brass easily resized to 22cm?
