Hey Scott, I might be able to shed some light. I have a thread here regarding Swift A-frames and shot start pressure that will help clear things up a bit. When I fit QL to Hodgdon data for Hornady 225sp and then use the Swift manual load data, QL was 2723 fps at 98% load density vs Swift of...

thanks. the actions maker are top to bottom: GMA, Mayfair, GMA, Prechtl, Prechtl, Mayfair, Mayfair

Good advice! I went long about 5 years ago while I was still working:) I am a fan of Mauser square bridges and integral rifle barrels. Actions are setup for (top to bottom): 505 Gibbs, 458 Winmag, 416 Rigby, 375 HH, 404 Jeffery, 9.3x62 and 7mm-08. I should note that since then, i was lucky to...

Davidg8480, actually, I compliemnt you for questioning! Your question stirred my interest and I generated the info in this thread from my study. Thanks For now, my working hypothesis is that due to the thick copper jacket and copper partition, the Swift needs higher pressure to engage the...

Well, as the saying goes "a man with one watch knows what time it is but a man with 2 watches never knows":) or as Bob Vyne of Motorola used to tell me as a young engineer "who's who in the zoo". below is the data from the Hodgdon Manual No. 27 that I used: for the same h335 load, swift shows...

Buried in snow here, nothing better to do... Using Hodgdon manual and of all the load data, only the 7mm-08 has data for hornady and swift a-frame same bullet weight. Here is the data: Hodgdon Data:7mm-08 powder charge vel. psi 139 gn hyd sp, OAL=2.800, 1.157, 0.382 h414 45.5 2710...

Still available

Thank much for the insights!

not exactly a "ghost" shoulder. Once fired, neck sized with 0.530 bushing.

That is the reamer my rifle is chamber. Manson and crew are the best... Mr. Crank, perhaps you can shed a light. My Jamison brass neck wall thickness is11/1000. But the 495 drawing indicates Art was thinking 16/1000! (not sure why as the 500aa and 470 capstick indicated 12 and 11 thousands...

Perhaps an alternate view of a Rolex purchase is it is an asset: "a useful or valuable thing"

Swift manual only shows the maximum Saami OAL, not what they actually load the cartridge. For me, I always load and crimp to the top of the cannelure to prevent bullet setback from recoil. The 3.49" OAL per Hodgdon is to the top of the cannelure. Swift A-frames have a wide cannelure, around...

the 3.49 OAL is correct for the 275gn Swift (their bullets are usually seated deep). And both were using Remington cases. My experience with Swift manual is the loads seem conservative. for what is is worth: 250 gn bullet, h4831, 338 RUM Manual max load Barnes 84.0gn Hornady...

bought my first Rolex in 1989 (coke GMT) and my 2nd in 2015 (Sea dweller). Retired now on a ranch in the mountains and wear my Sea Dweller 24/7, working around, plowing snow, repairing fences, chain sawing fallen trees, etc. Used to worry some. But when I saw Philippe Cousteau watch realized...

“Never argue with an idiot. They will drag you down to their level and beat you with experience.” Mark Twain

those work, particularly in the warmer climates. Do not have any doubles, just bolts... good point. Sad to say, most of my rifles are in the collection but I do have a few to bang around with. Regarding my spelling, i think Jeffery404 was taken and I accidently kept typing:) I wanted 505Gibbs...

well, a steady supply of customers helps:) Unlike many years ago, with the CAD today, the drawing, toolpath generation and posting to the CNC, is just work. If you screw up, just re-fresh and start drawing again. The most labor is in the fixturing and the final filing and polishing. as this is...

this is an African forum but thought folks might appreciate this pair. My gunsmith made these for himself and being a nice guy, sold them to me. They both have his integral barrels (which I am a fanatic on) and pre-64 actions. Top is 375H&H and the bottom is 7mm RemMag. As a pair, I normally...

Sorry I forgot the obligatory photo:) (took puppy for a long walk in the snow and she wore me out...)

While I am waiting for the A-square rifle to sell, got this from CZUSA before the end... Per previous info, mag. box is 3.75" long, bolt face is 0.532" with follower, extractor and box width setup for any cartridge similar to the 375HH. $1175 shipped ffl2ffl. Thanks Steve

This is the route I went. Was able to get a nice stock from CZ (when you still could) and a 416 Rigby action, Wiesner drop floorplate (holds 3 down comfortably), express and NECG peep sight. Rifle weighs 10.6lbs. I should note we used two 0.3125"x6" tungsten rods to add 0.57lbs in the butt. It...

Smokepole got back to me and graciously passed. Thanks

Smokepole is first in line although he has not gotten back to my PM. Spoke with Dave and he is 2nd in line.

Good to know. Thanks.

Tried to reply but system said conversation was closed?

No, never had rings

I order this rifle from A-square in 1985 and has been in storage since then, but moved states a few times. Wanted a Rigby and at the time, seemed the only available option. Anyhow, test fired by me once with A^2 ammo and recently, with Federal to check it out. Price is $3375 shipped FFL to FFL...

Sold and shipped. Thanks much. Steve

I ordered my 416 Rigby from Asquare in 1985 as only 416 factory available at the time. It has vague receiver stamps on the left side, RE on the top, bolt is stamped with number and only other markings are on the barrel. Serial # indicates receiver made in 1918. Steve

SLG, I gave all the info you asked for (put in 3 Hornady cartridges, measured the LOP, weighed the rifle,, measured the barrel length, photo of the rifle. As I was the original owner of this rifle and purchased in 1985. Since you had been looking for a while, I felt you should already have a...

Sold pending funds. Steve

No. Tim, at Matrix Gunsmithing, only machines drop floorplates , custom followers, triggers, integral barrels (currently he is the only retail supplier) , mostly for his cz550 upgrades. Thanks

A gentleman asked about this on a Krieger #6 barrel contour. So thought might be of interest here. It is matched to a Rem 700 action with Talley scope bases, NECG 1 standing, 1 folding express sight and NECG 9mm tall small gold bead front sight. what it would look like on the Krieger bull...

Gentleman had question regarding the Rigby, so here are today photos.

The 450 Rigby would be perfect. Tim, at Matrix Gunsmithing, has done quite a few rifles using the CZ action. I should note, that other than the 458 winmag, all of the cz rifles used same magazine box from 375 HH to the 500 Jeffery and 505 Gibbs.

Was a question regarding the mag. Box Looking thru my records CZ used 2 mag box: 375hh for everything and a 2nd box just for the 458 winmag. 3 followers: 375hh, 416 Rigby and 458 winmag and 2 extractors, 375 HH and 416 Rigby. Thanks

For clarity. All of the qrib top surfaces are parallel to the barrel boreline, no slopes. The slopes occur where the qrib interfaces to the barrel profile. These are elegant parts and designed for NECG front beads (of any choice) and rear express sights (1 or 2 folding). Would not cut into them...

Gentlemen, thanks for all feedback and interest. Regarding Ruger #1 and Ruger Hawkeye, these can be supported. The quarter rib is profile to any barrel contour and a 1 off custom is not a problem. Just need to know the barrel profiles. More info coming. Steve

Bought these direct from CZUSA in 2021 before they stopped production. Setup for Rigby length cartridge. Oiled and stored wrapped in brown paper. $1125.00 shipped ffl to ffl. Thanks Steve

Yes it can. If you provide me with the barrel profile (breech diameter, length of radius contour from the breech to when the barrel becomes linear taper and the barrel diameter at that point, will put in my data base. Thanks Steve

Tim at Matrix Gunsmithing. He plans to clear out his CZ upgrades by Feb. He has done quite a few on the B&C stock with mercury tubes (he also fills up the buttstock hollow). He even makes an integral barrel (machined in quarter rib, banded sling swivel and banded front sight base) that has the...

From Wesley Richards website: “ The New .500/.465 NE The .500/.450 NE was very popular for Holland’s but the banning of the .450 caliber rifles forced the firm to develop something new. Using the same parent case and bullet weight as the .500/.450 NE, but loaded with a .467” diameter bullet...

gunsmith thought I should have something different than DGRs, so I ended up with this... The scope is an original Unertl 16x with adjustable parallax. Kinda like sighting thru a straw:) But when that gets old, it has an original Redfield aperture sight with Globe front sight. Not quite a plains...

My favorite LAPHROAIG 10 yr., from Islay the peatest I found, maybe even a little seaweed mixed in:)

Long rifle:) The Big 3: ground hogs, ground squirrels and gophers!

bullseyes camera system. Camera you setup near the target and sends video to your iphone, etc. Then, used the software to analyze the shots. Not quite a 404:)

Full featured with express sight, quarter rib and a drop magazine that holds 5 down! Bring them on... Heavy Remington factory ammo, minute of ????

looking to see how much interest there might be in these items for gunsmiths. These are CNC machined, filed and polished. These can be either standard barrel profiles, such as Douglas, etc. or custom profiles. They are machined to the exact barrel contours, ensuring a seamless fit. The banded...

Like your call sign! as the Gibbs is my favorite. N560 is a good choice. I went with the n165 as lower bulk density and a bit less energy content so as to get nearly 100% load density, P.S. I grew up just outside Sac. In Fair Oaks:)
