20 Practical Velocity

[coupalr]

I just cronographed my new 20 Practical. It is a 1-10 twist Shilen barrel on a savage Model 12 single shot action. I am getting 3950fps with 39gr Blitzking over 24.5gr of RL-10X lit by a CCI 450 primer all in Lapua brass. This combination is very accurate and it is going to be alot of fun this summer shooting gophers.

What is your case OAL plus your barrel length too. Ive just ordered a reamer and barrel to make one up. It will be finished at 25 inches. Was hoping for around the 3700fps mark with the 39gr blitzkings with benchmark and CCI BR4's. Maybe i will try the 10X too....

I use a std 223 load..26/H4895 but with the 40 gr V max moly...rechambered 12 twist/3 groove Pac Nor...25.75" long with no taper...1.055" @ the muzzle..Savage s/shot action....awesome cartridge....Win & Lapua brass....p/dogs hate it ! Pic shows early load development with 40 V max...

I had no idea that velocities were this high... Im going to love the 20 practical i think. I will try the H4895 for sure, its easy to get it here.

I'm just getting started with mine but so far I'm likin' it. Initial tests show ~3,500fps with 35g Bergers in my 18" AR. I've also started working on 50g Bergers,Shilen 9 twist) but I don't have any chrono data yet.

Seriously thinking about building a bolt gun now too!

btw, thanks for sharing the info on the Viht powder in the short barrel. I'm gonna have to try that in my AR....using H4198 with the 35 Berger right now.
