The straight-walled 414 & 445 Super Mag loads used by the Silhouette shooters back in the 80s/90s recommended Lg. Rifle (WLRM) for the DW revolvers. I have put together TC G2 16.25" carbines in both and use WLRM primers for the XTPs and Silhouette bullets over 4227, both are accurate and have full powder burn.

Have noticed powder residue with W296 & 4227, any pressure concerns using WLRMs for the bottleneck 41GNR#2?

that is a good question. Any necked down cartridge

will produce slightly higher pressures and the more it is necked down the more pressure. That was one of the main problems with the WSM and WSSM cartridges, especially the WSSM. You have a cut down 416 Rigby cartridge necked down to 22 or 25 and that builds up a tremendous amount of pressure.

I have used the water hose description quite a bit when talking about pressures. You take a water hose with water running thru it full blast. You squeeze it down to about half that size, you build up the frontal and rear pressures considerably.

The same thing goes with a 44 Magnum necked down to 22 caliber. I have knows several cartridge developers to try this and have damaged frames and cylinders due to the maxed out pressure. That is why I try to stay with stepping it down no more than 2 steps. Like the 44 Mag necked down to 41, one step.The 410 GNR surprised me that it worked and worked great as it was stepping the 454 case down 2 steps, to 44 and then to 41, but it worked. The pressures are about the same as a 454 so it is only in a 5 shot cylinder.

But the 445 down to 41, is no problem. At least I have never seen any problems with it. As far as the rifle primers or pistol primers if the gun has an action job where the hammer spring has been lightened I prefer to stay with pistol primers. Rifle primers are a slight bit harder and you can easily get some light strikes.

As far as powder residue is concerned, usually using a slightly heavier bullet will stop that. The heavier bullet will be in the barrel a micro second longer and will help burn the powder. Also using ball powders a magnum primer is always the best way to go. Every loading manual I have ever seen always reminds people to use magnum primers with ball powders like 296, H-110, etc.

Thanks, I like the 210XTPs & 210/220 SIL bullets

and thought the LR primers would give a cleaner burn.

The 240gr MBW/4227 we used in Africa 2017 is never a problem, as you said, heavy bullet=clean burn. In my opinion, perfect bullet in the 41GNR#2 for penetration on Blue Wildebeest, Zebra, Gemsbok, etc. or Elk, large deer, etc.

I found a MGM SS 16.25" G2 barrel online that you had rechambered from 41Mag to 41GNR#2. Plan to use the lighter 210/220 Jkted. bullets with LR printers with that setup. Heavier LBTs, I'll stay with LPs in my GNR barrel.

A-frame

Try swift 210gr. A-frame. Much heavier constructed the XTP.

Will do Alcorn, thanks!

The top carbine took 10 critters on the June 2017 Africa trip with 14 shots handloaded with the 240gr. Montana Bullet Works LBT. The wife took a real nice Blue Wildebeest with 1-shot, dropped where it stood. Same with her big Warthog, Springbok.

Bottom: The little 4.5# SS barreled 41GNR#2 carbine I setup today is dedicated for the 210/220gr. jacketed loads. Easy carry, accurate & plenty of bang for FL & TN hogs, etc.

Both are very accurate out to 150-200yds.

Great looking practical weapons.
