Guys I was discussing my new build with a few guys and twist rate and bullet weight came up. I'm sure this has been discussed on here but I do have problems with the search engine on here. Little help if you like...
I have an M40 profile 20 inch barrel with a 1:11 twist on a rifle I am building. My school of thought based on experience and/or take always from Applied Ballistics is that more than around 168gr projectiles out of that rifle wouldn't give me the best accuracy. Given its a friendly competition gun, a hunting rifle, and just a nice fun tool; so I understand I'm not talking about a bench rest gun here. However should I expect less gyroscopic stability from a shorter slower twist rifle compared to a longer barreled faster twist rifle? Should I not push 175's, 180's and such through this gun and expect it to give me the same acceptable accuracy I will expect out of my Match 168's? Or.... Should I expect better?
In addition I do understand some rifles like some loads better and different powder loads equating to a lower Fps or higher Fps could impact the load accuracy. Thoughts?
