.32 barrel and twist rate

[motorcycle_dan]

I just recently acquired a Benelli from a Bullseye-L member. Whatta sweet pistol. I plan to eventually shoot it in bullseye CF competition both indoor and out so need accuarcy at the long line.

I'm told the secret is to get Dave Wilson to install a custom barrel which has a different rate of twist. This will stabilize the projectiles past the 50yd long line.

My questions. The stock vs. new Dave wilson twist rate. Anyone know the difference? What about bore diameter. I've had one exchange of e-mails with Dave. Price is fair but out of reach until I pay off all my post Camp Perry credit cards.

I understand he uses Shilen stainless steel barrel blanks. Anyone have knowledge of his .32 SWL barrels? What twist rate? What is the bore diameter? What type of bullets does it require to shoot well at 50yd?

Thanks for the help

Dan,

You've got his email address - why not just ask him directly?

Curiously,

Dan-I got a Wilson bbl for my Pardini HP. With Speer or Lapua slugs there is no problem at 50 ysrds. The twist is 10 inches. Groups of less than 1.5 inches are not uncommon.Even DEWC shoot pretty good.

I believe Earnie's barrel size is 3083 or 4 but you might ask him to be sure. Good Shooting Bill Horton

My appology to all. How can I get hold of Dave Wilson. I've been wresling
with the idea of using a .32 cal. pistol for center fire, in Bullseye competition.

Thanks.

Josed.

I had a barrel made with 0.308" bore and 1:10 twist. Worked well on a Walther GSP.

TonyT,

If you had the barrel replaced with a .308 what bullet are you using and what is your powder load? The reason I ask is that most lead bullets are .314 dia. with a .006" size difference do you experience any pressure issues or are you using a .311 jacketed bullet of some type?

Darius Young used a .308" barrel in his Erma 32 pistol for years, very successfully, I might add.

[Stephen51861]

I do not doubt at any moment that he or others used the .308 barrel. My question is, what bullet did they or anyone currently use with that diameter bullet.

Greetings,

Doc Young used to shoot H&N 100 grain bullets sized 0.312" in his ERMA.

I use Speer, which measure 0.313"-0.314", in all my barrels ranging from 0.308"-0.314" groove diameter.

There is about 30 FPS increase in velocity going from a 0.314" to 0.308" groove diameter barrel.

Doc also had a great supply of Lapua Commercial ammo that he shot in his 0.308" barrels with no problems. Lapua commercial is 0.313" to 0.314" bullet diameter.

Cheers,

Dave Wilson

I had a barrel made with 0.308" bore and 1:10 twist. Worked well on a Walther GSP.

I used the Speer 98 gr. 0.314" and Hornady 90 gr. 0.314" with Don Nygords recommended load of 1.5 gr. WST. Excellent accuracy and no signs of high pressure.
