G'Day Fella's,

Thanks JFE, for your info on this Rifle/Cartridge combo!
Thank you also for the reminder on the recoil aspect, with this rifle!
I now recall reading something about what Rossi did to reinforce their 92 Puma's, chambered for .454 Casull! Apparently a lot of use and recoil can shear off the forward (just back from the muzzle), magazine cap retention screw! This is the screw (just back from the muzzle),that holds the magazine cap in place. This screw also locates in a small hole in the bottom of the barrel and when the screw shears off and then eventually falls out, the mag Cap and Spring, head off for parts unknown!!!

This rifle has the above mag cap screw and also a hanger that is around 3 3/4" - 95mm back from the muzzle and this has a 1/16" cross pin, that also partially engages thru one side of the mag tube. Not sure if that will help but I will keep an eye on it and the screw.

Not long in from the Funshop and this rifle appears to have a 1 in 28" twist, a 6 groove barrel with a bore groove diameter of 0.451". Daryl, I hope this addresses that question for you.
My hope now, is that this will stabalise the heavier bullets?

Further to this the .45 Colt has a maximum cartridge OAL of 1.600".
With the www.frontierbullets.co.za (RSA) 300grn 0.451" Complete Metal Jacket (CMJ) bullets I plan to shoot through this rifle, seated to the forward edge of the canelure, it has an OAL of 1.650"! The two dummy cartridges I've loaded up, still feed through the mag and into the chamber, as smooth as any 92 Win. Looks like things should be OK!!!

Doh!
