Parker Hale 1100M 458

[9.3mauser]

Parker Hale used a proprietary mag box that was heavy duty steel and wider than a standard mag box, so you could fit 4 in there without extra depth.

For the Husqvarna 9.3, there is too much taper at the front of the mag box and rails. I would bet that 5 .30/06 rounds would fit in just fine, but the 9.3x62 has less body taper, and the cartridges get all bunched up at the shoulder. I solved the problem with an aftermarket Blackburn mag box. A competent gunsmith might be able to remove a bit of material from the rails so the rounds stack properly.

What kind of mod? - usually, an amount is ground off the front leading edge of the standard extractor - makes like a slope or ramp so the extractor nose's edge can slide over the case rim and snap back into place to grip and extract that case. Works well. Easy to screw up by grinding just a bit too much. Also good to check that your receiver has enough room to the side - so that the extractor has room to go to the right when it goes over that rim. Is claimed by some to result in a weaker lip to the extractor - is thinner at the leading edge, for sure - if carried away, perhaps change the heat treat characteristics and make it more brittle - I don't think that you want that. When "single loading", you have lost the "controlled round feeding" for that round - so is possible to drop a shell into the chamber, partially close the bolt, pull back the bolt and get hold of second round, and forward motion will try to push second round into chamber that is full with the first round. Full "controlled round feeding" does not ever allow that to happen.

"Put one under the extractor" - that is usually done by filling the magazine full, then remove bolt from rifle - snap a round into the bolt face - then reinsert that bolt - will take some fussing to depress the rounds in the magazine, with a round on the bolt face - else the closing bolt will jam up, trying to bring a second round up from magazine. Is not meant for "topping up", I don't think - for initial loading, to get a round in the chamber and full mag. I suspect if a full mag is important, that idea to chamber one, then flip over and fill mag from bottom, through hinged floor plate, is easiest for most - is exactly the way Schultz and Larson factory instructions say to load their rifles. An S&L follower is "ambidextorous" though, so does not matter left or right first - a Mauser follower is not - have to get the left and right correct sequence to get a full mag.

Thankyou for the infos. I was curious to know but i wont mess with the rifle, work perfect the way it is. If i wan to load at full capacity, easy to fill mag from bottom as you said. That P.H was too good deal to pass on. To me, that rifle feel better in my hands then the Win 70 i had,maybe because seem heavier.

Haha - although I do own a 458 Win Mag, I have not yet fired it with full power loads - I have 30 x W-W 510 grain factory loads on hand, should "push come to shove", for some reason. An acquaintance who has, a lot, assures me that "heavy" is your friend - like 10 pounds or more. Even 12 pounds is not "too much". Is definitely a "step up" from a 9 pound 375 H&H, apparently. As per him, he thinks I am pretty much "nuts" to consider touching off this 8 pound Zastava with full house 458 Win Mag loads - at least, more than once.

I love my 458 wm. Interarms mark x. Sure knocks black bears and grouse down

I disassembled the P.H to see what i could learn. The date code is "Z" and according to google,that is a 1974 rifle. On pictures, we can see the bedding,the weights added in the forehand and in the buttstock. Once the stock is removed from the rifle,we can really feel how the buttstock is heavy with thoses weights. With the bedding and the additional hold down screw,tha tmake the action very secure in the stock. BSA knew what they were doing. In all, that's a very neat rifle

Good pictures - was helpful to me to see how that auxiliary recoil lug was attached to barrel and seated in forearm - the Zastava here in 458 Win Mag does not have that - I think it needs to have one, before I break this stock... A Winchester Model 70 in 375 H&H had that auxiliary under-the-barrel recoil set up, as well as the two stock cross bolts like you showed in your earliest post. Looks good. The vertical bolt up through forearm into stud on the barrel - a 1955 Winchester Model 70 here has similar - seemed to be a thing for working rifles, before "free floating" became the thing to have.

Never could figure out why, in later years, the Birmingham Proof House would put the proof marks under the stock line out of sight, when, at least to me, they were part of the charm.

And, for the record, the OP's new-to-him rifle was MUCH nicer to shoot with full power loads, than my 8# Whitworth in .458, even after I had that one Mag-na-ported & had 2 Edwards mercury recoil reducers installed in its stock. It was just stupidly brutal. (My 8# Whitworth in .375 H&H in comparison, is a pussy-cat; I've been kicked more with an Ultra-light 308 Winchester with a too-short stock) After 5 rounds rapid-fire standing [before my divorce in '83, I was planning an African dangerous game safari], I was dizzy & had a headache. Saw stars, too, which, apparently, is the beginning sign of a detached retina. It was somewhat better when I put a lead-shot sissy bag between my shoulder & the butt, but then the LOP was all wonky & who the heck carries a bag full of lead shot when they're elephant hunting anyways. And that was 40 years ago when there was a lot more muscle protecting my joints! Ah, but you should've seen those squashed Remington 405 grain FP's explode on charging hunks of granite at 2,450 fps at the Yellowknife range! That was more fun than seeing the 0.458" holes cut through the steel plates by the old Hornady RNFMJ's.

Are we having FUN yet? (to which the proper reply at my age is: I'm Too Old for this $#!T!)
