Anyone familiar with Winchester WXR?

[Alan in Vermont]

I got a good deal on nine pounds of powder today, all Winchester, 4 of WST, 3 of WSF and 2 of WXR. The first two will fuel 45 ACP and .40 S&W, maybe not the ideal choices but certainly usable. I've done some searching for WXR data and only find snippets of info. The only thing it may work in is our 6.5 Rem Mags but I'm not sure about that yet. At first glance it seems like it is great in the short mags and the bigger belted cases. The deal was good enough for just the pistol powders so I can throw this stuff on the lawn and not get hurt but it would be nice to be able to use it. The 6.5 RMs are the only thing I have that likes the slow burners.

Anyone got any input on this stuff?

Got the whole bunch for $140 out the door so having it in there was not a deal breaker.

Here is what I could find on it online. It appears to be close to Reloader 22 and most of the data found used RL-22 data. Oh yeah number 142 on the burn rate chart.

Winchester WXR Powder Rivals RL22 at Much Lower Cost ($13/lb)
Here’s a good deal for magnum shooters on a tight budget. If you need a quality, slow burn-rate powder suitable for large-capacity cartridges, check out Winchester WXR powder. Production of WXR has been discontinued, but quantities are still available. PrecisionReloading.com has 8-lb jugs of Winchester WXR for $104.49, which works out to just $13.06 per pound. Grafs.com has 1-lb containers of Winchester WXR for $13.99, on “close-out” pricing (limited quantities, no back-orders). Winchester WXR is a Swedish-made, double-base, slow-burning extruded propellant used in larger-size cartridges. WXR is an excellent choice for the .25-06, .270 Win, .30-06, 7mm Rem Mag, 300 Win Mag, 7mm WSM and 300 WSM cartridges. Some industry observers have suggested that Winchester WXR is virtually the same as Alliant Reloder 22. We can’t confirm that, but the load recipes are similar. Keep in mind that, at $13.06 per pound, WXR is nearly six bucks per pound cheaper than Reloder 22 (in 5-lb containers).

The Reload Bench’s Burn Rate Comparison Chart shows WXR having a burn rate very close to Vihtavuori N165 and IMR 7828. In tests with a .25-06, WXR delivered velocities 30 to 60 fps higher than Reloder 22, with equal loads grain for grain (see WXR vs. RL22 report). In the .25-06, the WXR was slightly more energetic than Reloder 22, so a max load with WXR proved to be about 1.0 grain lower than a RL22 max load. Another WXR user writes: “I’ve been using it for the last three years in my 7 STW, 7mm Mag, 300 WSM, 300 Win Mag, .30-06 and .270 Win. It chronographs nearly identical to Reloder 22, so keep that in mind when working up loads with it. From what I’ve researched about it, the company in Sweden who makes powder for Norma, also makes Reloder 22 and made Win WXR. Remember powder can vary slightly from lot to lot, so start low and work your way up.”

Here is what I could find on it online. It appears to be close to Reloader 22 and most of the data found used RL-22 data. Oh yeah number 142 on the burn rate chart.

That is the same info I found. It looks like there will be some testing done to feed it to the 6.5s. Maybe I can find someone local who loads for one of SM or SSM cartridges. Because both our 6.5s are in Remington 600s we can't run bullets over 120 gr. with seating them really deep so they work through the magazine. I'm thinking this stuff would work good behind 140+ gr. bullets. This will probably be a project for next spring when I can sit at the range and work up loads.

WXR is the same powder as Norma MRP and data can be interchanged between the two. It was made by Bofors and is basically a variant of Rl-22 and starting charges for RL-22 can safely be used with WXR as well.

It looks like I need to go shopping for some newer loading manuals. I lost interest in shooting for quite a while, just got back into casting/shooting about a year ago. Still had all my equipment so it's not like I had to totally start over, just that there have been a lot of new additions to the components available while I was away. I've got a rack of manuals but nothing newer than 20 years or so, other than the Lyman #4 CB manual which, IMO, is a poor excuse for a data book.

May I suggest http://www.castpics.net/LoadData/default.html

I've been told(as said above) that its Re 22.I've been getting great accuracy w/it in 8x57. You can see data here:
http://www.intoku.net/Upload_Manuall...dersmanual.pdf
This was my earlier thread on it : http://castboolits.gunloads.com/show...107304-Win-WXR

Hope that helps!

I use it in 7mm Mag and 300 Win Mag, price locally remains under $100/8lbs but limited supply since it's no longer made. Great groups and velocity, starting loads same as RL-22.
