Please read below and reconsider your post. Good day.550 Magnum is based on the 460 Weatherby case, hence is a belted magnum and headspaces off the belt.
It was made in shortened 460 wby brass blown out calld express, full length 460wby brass blown out, full length 505 gibbs brass blown out. Have plenty of 505 blown out .550 head stamped brass aswell. Plenty of actions aswell. That is why I am wavering. I am not in a hurry. Probably build it on GMA ACTION WITH 505 GIBBS FOR THE CASING.
Now kindly back to my question... how does the .550 based off the Gibbs case headspace?
Free recoil is about 133 ft-lbs at 27 ft/s...but a maiden's kiss...like a mule...230 in that weight rifle's gonna leave a mark! What is the parent case?? Many other big bores have several pounds on top of that which of course help to maximize accuracy and minimize recoil.
From what I have heard is with 26 inch heavy barrel, weighted stock, it is milder than other .5 calibers. I have not shot mine but . He may be able to shine some light on this @RR 314Free recoil is about 133 ft-lbs at 27 ft/s...but a maiden's kiss...like a mule...
Welcome to AH Steve. @Jefferry404Gentlemen,
Saw this thread and thought good time to introduce myself. My name is Steve and I am the design engineer of the integral barrels for Tim at Matrix Gunsmithing.
Tried to post photos and a longer message but I keep getting error message about security or content.
If this post will try again with photos, etc.
Jefferry404, between you and Anthony George, it would be great to see you co-ordinate on large caliber, D/G bolt action rifle builds. Very much of a like mindKrish,
thanks for the welcome. My main interest is large bore bolt rifles, mostly with integral barrels and I am quite fond of the newer Mauser action clones such as GMA, Mayfair, Prechtl (which is the closest to original) and of course, rifle barrel design.
