Home Forums Reloading Big Game Rifles Bullet choice for 8 in twist 22 Creed?

I left this question in hunting rifles, but no response. So I'll try here. Thanks in advance.

I have been through the Hornady manual. It states the need for faster than 10 inch for their heavy bullets.

On the other hand I see references here often of 7 inch twist.

Will the 80s work in this barrel? How about 88s? All cup and core, poly tip, and boat tail.

88's will work in an 8 twist 22-250. The Creed is very similar. I thought most knew that here. We've had many threads regarding the fast twist 22-250, and the use of 88gr ELD match bullets.

Thanks, good news. Yes, the 22 Creed is simply a 22-250 very improved.

I have not partaken of previous discussions as I was not working with the Creedmoor at that time. Until now I have only used 14 in twist 22 cal barrels.

An 8” twist will stabilize those longer bullets, but you won’t achieve the maximum BC value. Use the JBM (for tipped bullets) or Berger stability calculator. The Berger calculator shows the effect of stability on BC.

Those are rabbit holes I have not dived.

I am just looking for 1/2 moa accuracy to 600 or maybe 700 yds. In extremely calm conditions.

The 88 ELDs worked fine in mine.

Lotsa good things said on Snipershide about the Berger 85.5

88s will shoot fine, but as Jordan said, you will give up a little BC.

Ah, you will like it. It definitely adds more versatility to the table. The heavies are much better in the wind. One nice thing about the Hornady 88 ELD match bullets, is they can be found fairly reasonable. I bought some from midsouth, 250 per bag. If I remember right, about $70/bag. Well worth it, for the performance you get out of them. In a different post, you said you wanted to get 1/2 moa out to 600 yards or so, in calm conditions. You should be able to do that with this bullet. I've shot them out to 800 yards on steel, but don't have any paper targets for that distance, that I can show you. I can hang paper at 400 though, and the lightweight Tikka T3x puts them in there. Here's a .8" 3 shot group shot at 400 yards, so Jordan's perceived loss of BC, may or may not matter much, even out to 800 yards, from my experience.


If your 22 Creed is anything like that Tikka 22-250, you'll have no issues shooting 1/2 moa at 600 yards.

I am glad to see your load data. I have a couple pounds of Superformance I was not sure how to use.

Thanks.

It's not perceived. It's factual. The actual decrease in BC when going from super-stable to marginally stable is not as much of a problem as the introduced variability in BC that changes with atmospheric conditions.

Jordan, thanks.

I doubt my perception is astute enough to appreciate the difference. Though I could see it when 60 gr ballistic tips key holed through the target at 100 yds with previous 14 inch barrels.

I have an 8 pound jug that seemed destined for a shelf ornament. Now that I have my 22 Creed built, I reckon the powder will meet its destiny.

Which forum might one find those threads?

This one. I even started some regarding the fast twist 22-250 using 88's. I ran different loads, using different powders over the chrono too, with accuracy tests. Over the last year or so, we've had many threads on the subject. Just got to search for them..

Jordan, I'm unaware anything in the Berger calculator that quantifies the drop in BC when that SG drops below 1.5.. Am I missing something? Don't doubt it drops, just curious as to how much?

If you look to the right of the calculated SG value, you’ll see the BC analysis.

https://bergerbullets.com/twist-rate-stability-calculator-updated/

On average, it’s about a 3% drop in BC per 0.1 drop below 1.5 in SG.

Thanks Jordan. I see that in your link. I must have been thinking of their older version.

I may need to try a test to see if it shows up on target. Both of my Palma rifles now wear 30" Obermyer 5R barrels chambered with the 2011 Fullbore .308 reamer. Both shoot the 155 Hybrid very well although the SG number for the slower twist is about 1.4 . I can shoot them side by side at 1000 yards and see what the velocity delta is with my e target.

Sounds like a fun experiment. 👍
