But i don't want a cartridge thats gonna be hard on barrels like that. Let me know what your experience is with that cartridge. Thanks!
I have not seen any barrel wear more than normal, But as I said earlier there were some requirements when going to a cartridge this hot.
I did lots of research before I built mine, and talked to some well known gunsmiths to get there opinions and this is what I decided to do.
Barrel= I went with a 3 grove stainless Lilja after talking to Dan Lilja because he designed the 3 grove specificly for the varmint hunters that shot thousands of rounds of high velocity 22 cal
rifles. The lands in the 3 grove are wider giving them a better wear rate. And stainless because
it has better wear resistance also.
The 1 in 15 twist was because of the intended velocity and because the faster twist barrels are
very hard on bullets at these velocities.
I use the 40 grain ballistic tip because it has a thicker jacket (Nosler had some failures with the old thin jacket varmint bullets and made the change for the varmint hunters) and I have had zero problems with them shedding there jackets or loosing accuracy
I have not tested anything above 60 grains in my rifle but with bullets up to 90 grains and BCs over
600 the WSSM should be impressive but the twist would have to be altered to 1 in 10 or 1 in 12 to work.
The really fast twist used in the 223 ARs (1 in 7 or 1 in 8 would be to fast for the WSSM velocities.
I have not pushed my 223 WSSM to max yet (Because it shoots so well) But one day I will see just how fast it will accurately shoot and group.
