I've heard stories of a mythical extended magazine for it, but I've never actually found any for sale on the Internet. Quote:
I think the Remington 740/7400/750 would be a very old-fashioned, economical choice compared to many of the ultra-modern, fashionable alternatives. Which will suit some characters, certainly. Quote:
However, I thought that the Remington 7615P just came in 5.56x45mm NATO/.223 Remington and if you wanted the gun in any other chambering, you had to get the Model 7600.** Have you seen a Remington pump-action rifle in .270 Winchester with all the features of the Model 7615P, including an extended magazine the size of a 20-rd or 30-rd STANAG? *The best shot who has been encountered in the campaign can fire two aimed shots per second out to the maximum effective range of most cartridges (the range where it goes transonic, usually), keeping them within a circle more-or-less matching the mechanical accuracy of the gun. **Which, granted, is pretty much the same gun, but doesn't use STANAG magazines and lacks several other minor features that make it a dedicated Police weapon.

This gentleman apparently made one for a 7600 in .270
https://www.youtube.com/watch?v=cw2I-mzGZvM Here is his website for ordering things from him, with a nice pic of the rifle in question https://www.doublercustom.com.au/Rem...5_Mod-W17.aspx I see lots of 10round magazines on Ebay, not 20 sadly |

You can get the Browning BLR chambered in many calibers, up to the excellent 7mm Remington Magnum, but with Shots 3-5, it doesn't make much of a battle rifle. And from what I can tell, if the magazines were any larger, they'd make it hard to work the lever smoothly, anyway. Semi-automatics exist in chamberings like the .270 WSM, 7mm-08 Remington and 7mm SAUM, but if they are designed for hunting, they'll rarely offer larger magazines than 5-rd. How difficult is it to design and make a high-capacity magazine for a rifle where no commercial magazine models exist to imitate? What kind of Armoury (Smallarms) check are we talking? Do we need the Invention rules and Engineer skill? If so, what complexity?

Re: [Modern Firepower] Technothriller gear for secret DHS team in 2017
The gunsmith I linked to had made a high capacity .270 Win magazine for his Remington 7600
Numerous 8-10 round magazines for the 7600 exist So it would be far from an insurmountable challenge I expect to make a 20 round magazine I'd guess probably be a Armoury Small arms with a say -4 penalty and a machinist check if I was forced to guess |

Edit: Here's an example of an extended magazine where it looks as if someone didn't notice he'd failed the first Armoury roll, and built a 90-round AK-47 magazine by welding three 30-round ones end-to-end.

It doesn't say anything about how long an unmodified design phase and a manufacturing phase are. I'll guess that the latter depends heavily on tools, but what ought one assume allows an Armoury design roll without a penalty for Time Spent? I'd modify the difficulty for rounds that are operating at the limit of the magazine length, challenging to feed reliably or otherwise known to be harder to run in an autoloader, like the 7mm Remington Magnum, .300 RSAUM, .300 WSM, .300 Winchester Magnum or .338 Lapua Magnum. As some of these have challenged established commercial manufacturers to turn out, I might even require an Engineer skill check to design them. Quote:
I'm assuming that the Browning BAR, Browning BLR, Remington 740/7400/750 and the Remington 7600 all have detachable box magazines. Is that not right? What rifles that you are likely to buy in the modern day have fixed box magazines? Quote:
Without GM-imposed TDM for operating at the edge of the performance envelope, it would be trivial for someone with Armoury -18, such as one of the supersoldiers, to quickly design and built Fine (Reliable) extended magazines in .300 Win Mag or .338 Lapua Magnum. Or, for the AR-10 platform, .300 RSAUM or .300 WSM. And it would cost less than $3,000 for a weapon chambered for them, probably. As simple Malf. Crit versions of semi-automatic rifles with extended magazines that feed such long, powerful long-range cartridges are either more-or-less unavailable or are sold only as high-end custom rifles that cost well north of $10,000, that might be unrealistic.

No, the problem is that the .300 RSAUM, .300 WSM and similar magnum builds in AR-10 type rifles that graced gun magazine covers in 2009-2014 or so had severe reliability issues. Magazines wouldn't feed or the long rounds wouldn't chamber right. And that's professionally made rifles and magazines, by someone who presumably has an expert on staff. As for the newer offerings, I haven't heard yet whether Alexander Arms, Albert Arms, NEMO, THOR, Falkor or the other luxury/tactical gun manufacturers have solved these reliability issues for their $10,000+ rifles. They are new enough so that most of the data is from gun writers who may or may not be paid by the manufacturer and, in any case, are shooting only a few rounds under very controlled range conditions with gun and ammo chosen by the rifle maker.

Re: [Modern Firepower] Technothriller gear for secret DHS team in 2017
It's pretty easy to change the bottom metal on most "hunting rifles" to one that takes AICS magazines, which are a very popular standard magazine. Trivial actually; they are usually a drop-in part. Voila, you have 10-round detachable magazines on a hunting rifle. Alpha Industries makes some of the best ones, albeit only in a few calibers. (.308 and .338 are the most common.) See GA Precision for a lot of examples of Remington 700s with AICS bottom metal. Heck, MagPul makes them, too. This all holds true for most other common modern hunting rifles, which means most common bolt-action tactical rifles, too, assuming that you can find one that lacks a detachable magazine to begin with nowadays.
But any .308 magazine will also take anything derived from a .308 parent cartridge, like .260 Remington (very similar to 6.5mm Lapua or 6.5mm Creedmor), 7mm-08 (which is very similar to .270), .243 Winchester, .358 Winchester, .338 Federal, 45 Raptor (which is a lot like .458 SOCOM, but does need a modified magazine follower), or 6.5mm Creedmor (which being derived from the very similar .30 TC is close enough to .308). So really, to get a highly accurate 20-round semiautomatic in such calibers you just need to re-barrel an AR-10, which is also almost trivial. Well, assuming that you're using loads without too long of an overall length, but I know that .338 and .358 ARs have been made, by Wilson Tactical if no one else. Get a barrel wrench from Brownells and change them yourself. The .260 Remington is very popular in ARs, and is currently fighting 6.5mm Creedmor for market supremacy. (The 6.5mm Lapua seems to be disappearing from the US market.) The .243 has the problem of short barrel life so it has lost popularity. And then remember, all you need to do to change calibers on an AR is to swap the upper, so you could have a quiver full of uppers of various calibers. Also, for the record, my vote is that anything from Wilson Combat deserves the Fine rating. Personally, if I wanted a hard-hitting long range AR-15 I'd be far more interested in 6.5mm Grendel than .224 Valkyrie. But I'm a 6.5mm fanboi. The .224 does have impressive external ballistics, granted, but I bet it burns through barrels at a startling rate. Icelander, have you ever considered that your GURPS habit has lead you to be unusually familiar with U.S. gun culture? To a level that might disturb a lot of your countrymen? :)
