Winchester XPR accuracy

If you buy one in 300wsm, let me know how long the box mag is internally -- I asked a few questions about them a while back and it appears not many people own one.
 
I'm not a WW rifle fan but I saw a new one 7mm rem mag a couple of weeks ago shooting from 100-500 yards and I was very very impressed...quarter sized groups at 100 to 3 inch or so at 500, as good as any out of the box rifle I've seen in many many moons...

Most of my shots will be inside of 300 yards

2.995 I have 2 of them. The first one shot so good, I bought another and made 2 semi customs. And I didn't have to buy after premium triggers either. The MOA trigger is hard to beat.
 
the XPR has a single stack drop mag, has anyone messed with cutting a slot/window out on a bolt action drop mag for longer loading???

I do this all the time on the ar-15 and ar-10 chassis metal mags--see pic below

if the poly drop mag for the xpr allows 2.995", then if you slotted the front of the mag, I bet you could get 3.05", maybe more? thus getting you close to the "ideal" 3.1" length needed for the 215 bergers --this may be another option for getting a long loading short action--Tikka has longer actions and you can change the mag and bolt stop but dang it, they have the strange 1:11 twist for the .308 calibers which is not ideal for the longer/higher BC bullets above 200 grains

What kind of groups are you getting out of your 300wsm
I didn't have a 300 wsm.. I had a 270 wsm and a 7wm. both shot lights out, but I built a 6.5 sherman short with the 270 wsm and a 338 sherman max with the 7wm.
The pic is my 338 max at 300 yds.
There a few drawbacks to this gun. One is the magazine length. It was fine for the 6.5 Sherman with the short action, but I did the 338 with the long action because I'm over 3" by a long shot. With a 300 WSM I would not do it on there short action with long bullets because they won't fit without taking up your powder space and there's no after market bottom metal . Two, the only after market stock for this gun is a Boyd's

any idea if the front of the mag was slotted like in my pic above, how long might the "magwell" allow you to load if the mag didn't limit it

in an ar15 you can go from 2.295 with an asc mag, out to 2.36 if you slot the front of the mag and there are no feeding issues at all--that adds .065" to the loading length, but poly mags are thicker, so if the xpr mag was slotted it might add .08" to your load length, making your max load length around 3.075-- that would be longer than a SA 700 with a wyatts box, but not as long as a LA for sure

I've done it with asc brand ss ar-15 mags, and the lancer L7 mag for the 308 chassis and it works great as long as you keep the slot inside of the magwell, dont make the slot any longer than the height of the ar chassis magwell

There Polly. And they're just like a tikka mag. I'll try to take a pic later. I took mine apart and took out a little steel plate in the front ( that I don't think I need) and it made a tad over 3"
 
Looks to be some variance in the XPR magazines (doesn't surprise me since they are injected poly mags)

I bought a WSM XPR magazine just to play with (before buying a rifle) and with the staock magazine I can get 2.970", if I remove the small metal plate in the front of the mag I can get 2.995"--If I were to slot the front of the mag with a narrow mill bit I could get at least 3.093"--BUT I know I can't get 3 full rounds in the mag at that length as I would have to slot the front of the mag right through the mag catch and I'm afraid it would not hold proper into the rifle without the full mag catch and the tips would snag the mag catch on feeding while in the gun

BUT that shows me that I could get really close to 3.1" (which is what I was looking for to load the 215 hybrid's) for the WSM cartridge in the XPR--on a side note, my win 70 in 7wsm allows for 3.025" so the xpr would allow for longer loading than the model 70

I spoke with Winchester and they kind of let on that they may have "new models" of the XPR for shot show this year so I think I'm going to wit to see what they come out with--looking at their "international" models, I'm thinking shorter threaded barrels is what we will see in the states as LOTS of their international models are threaded barrels and many are shorter barrels that what we normally see here in the US
