Hi guys, what do you think about the Winchester large rifle magnum primers. They are having a good sale on them at Midway. The price has me interested, let me know what you think. Thanks, BSA.

They are hotter than the Fed 215 which is hotter than the CCI 250.

I'm sure they are hotter than bosslady too, but that doesn't tell me much

I used them to shoot this 3-shot group last week (100 yds), 7 WSM, 160 NAB, 48.5 grains I-4831.

Use nothing but them for magnum loads.

When primers got short I bought 3000 of these plus some regular large rifle. Used them in .300 WSM and .300 ULTRA. They seem a little hotter than 215 as the chrono shows a little more velocity. Thier cups are somewhat harder as they dont flatten out as much as Federals. Accuracy is the same..still using them.

I bought several thousand a few years back for cheap. I think they're the hottest primer on the market. I also know they can be a bit smaller in diameter than Fed's and CCI's, which can make you think an okay load is "hot" due to what you perceive as an expanded primer pocket. Try a CCI and the "problem" goes away. I still load mostly WLRM's.
Anybody who seriously concerns themselves with the adequacy of a Big 7mm for anything we hunt here short of brown bear, is a dufus. They are mostly making shidt up. Crunch! Nite-nite!

WLRs are what I use for most loads but sometimes with large charges of ball powder I use the WLRMs. Especially when those loads are destined to be used in sub-zero weather. I like them.

Thanks, BSA. ...................I`ve used them for my 300 WSM and 375 Ruger with very good results, and will use them for a newly acquired 338-378 Wby.

I mostly use Fed 215s but in my heavy-barreled M-70 Laredo .300 Win Mag, I use Winchester Large Rifle Magnum primers.

Excellent feedback guys, I think I'm going to look for them at the gunshow this weekend. I'm assuming since Midway is selling them so cheap maybe the wholsale guys will have them there for about the same price. Here's the Midway sale on them incase some of you guys are interested: http://www.midwayusa.com/viewProduct/?productNumber=175457It's a heck of a good deal.

i found the 9.5m, 250 and wlrm all produced the same velocity in my 7mm mag and same sd. 215gm gave higher velocity and higher sd. norma manual has a chart. 215 are better than the others at low low temps.

Correction, that should have read 58.5 grains of I-4831.
