anyone tried 80gr pills in a 22-250?

I question if a 1:9" twist will stabilize an 80 grain bullet. I toyed with the idea of building a 1:8 or 1:7.7" twist .22-250, but decided on a 6mm BR instead.

I thought about doing the same thing. Then I realized that the common 243 will shoot 80gr bullets just as fast if not faster and do it without having to buy a special barrel. Plus it wil shoot a 55gr bullet at around 4000fps. And best of all it will shoot 100-105gr bullets for deer hunting.
The 243 will use a little more powder but for the savings in barrels and gunsmith work I can buy a lot of powder.

That may be, but the 80 gr. in 243 wont have nearly the BC.

I'd bet the Varget, H-380 etc. will be too fast. I'm thinking the RL-22 or even 25 would work if you can find the info.
Might want to call the powder mfg. If you can get them to fly, it ought to have a great B.C and maybe 12-15% better velocity than heavies in the .223
Somebody should have Quickload and whip up an answer.

Interesting Idea... I think it has a lot of potential.... unfortunately I don't have any info, but I am interested to see how it works...

go there, and fill in the blanks. use your calipers, and measure the 80 grain (A-MAX?). This will give you an idea if you can shoot, but there is not substitute for real world experience.

I'd be interested in the results, too.
I have a Remington .22-250 with a 1-14 twist. I was trying some heavier bullets and found it will not stabilize a 69 grain HPBT Sierra. It will however, handle a 70 grain RNPB from Speer. (The heavier bullet is shorter.) The 70 grain bullet is .791" long and the 69 grain bullet is .900" long.
A properly set up, fast twist .22-250 would throw a heavy bullet a fairly long way. The ballistic coefficient and the sectional density would be vastly superior to anything in the 50 - 55 grain range.
With slower powders, I could throw the 69 grain bullets at 3240 f/s - according to my chronograph. The fastest I ran the 70 grain bullets was 3100 and small change. I would think one could break 3000 f/s with an 80 grain bullet. Heck of an antelope rifle.
