I’m thinking of a Shilen barrel in 17 Fireball for a Savage Target action. I have no experience with the cartridge but am interested.
How do they shoot?
The one I have, I purchased from a gent that shot it very little and stored it for a long time. No idea of barrel maker. I only run 20 grain bullets and I use it out to about 200-225.
4198 and AA2200 is what it thrives on. I honestly have not measured 100 yard groups, but they are boringly small, 1/2” and better when I do my part.
If I have wind issues or I am hitting short I switch to my 17 Remington or 204 Ruger and don’t look back.
As far as brass, I use both 17FB and 221 reformed. I just sort them into lots that way, use the same load of 4198 and 2200 in both. They do have a different POI by a small bit, it it doesn’t bother me in the field.
I am now giving H322 a try. Like to keep my options open.
You mention Shilen for a barrel. I used a Shilen select for my 17Remington and do not regret it. Cleans easy and is more accurate than I would have dreamed. There are other barrels out there that are mentioned more, twist and groove offerings may be better if that is what you choose.
I can’t point you toward a small 20 as I have no experience, YET. I will admit to looking and would lean towards a 20-222 just because of brass availability.
I won’t be without a 17 center fire though, just a fun caliber as well.
Maybe those of us that use the 221FB case should hit up Starline with and email. I will say I would be in for a thousand or two. That would keep me busy for a weekend, lol.
