I did some research and loading for a friend this fall. We went to the "short mags"website and looked at loads. We compared them to our quickload program and found that alot of them looked pretty mild. We also found that Quickload says that the case capacity diff between a 7mm rem mag and the 7 wsm is only 1/2 grain!! Bottom line is that virtually any data that is good in the 7 mag is going to work in the 7 wsm. I guess to be on the slightly safe side I would step back one "step" when using 7 mag data. I found when posting and others replied that quickload was right on the money with it's velocity and pressure predictions.
Anyhow he had a browning autoloader and I've liked 4350 as a balance between fast and slow in a autoloader. Hodgdon's website said 57.5 under a 154/160 class bullet was max so we started at 56.0 even thought quickload predicted a very slow 2665 fps. We tried 4 different bullets at that load and they clocked just 2675 but they were wonderfully accurate. 2 of the 4 loads were doing 3/4" and all bullets went to the same point of impact. The bullets that seemed to shoot the best were the hornady 154 flat base and the 160 accubond. (BTW in my hornady manual for 7 mag it says that load should do 2700 fps....more proof of how these two rounds mirror ea other).
He wound up using the 160 accubonds (cause they looked cooler) for whitetail hunting. He got a doe. Even at that slow speed the bullet hit a little forward of where he was aiming and caught the leg bone on the way in.....it left about a 4" hole on the way out. YIKES.
I just bought a browning a-bolt 7mm wsm and have yet to shoot it -waiting on brass ,bullets etc..
On the recoil part -i have a rem. 870 express that has a recoil pad so hard it might as well not have one.I took a 1/8" drill bit and just started drilling hole after hole into the recoil pad from the back and completely through it also.This really softened it up and didn't effect the look much.
The way i looked at it was if this doesn't work oh-well i'll have to get a real recoil pad.I'll do the same thing to the browning if need be.
The a-bolt's come from the factory bedded and free floated ,the trigger is a joke !I adjusted mine all the way down -it's suppose to be 3-6 lbs adjustable mine is more like 6 lbs bottomed out.I'm getting a timney trigger spring for it from brownells.
If you don't handload you should start it's fun and usually the only way to really fine tune a rifle.
I wouldn't feel too bad about 2" groups w/factory ammo and trigger.If i can get to 5/8-3/4" for 5 @ 100yds i can live w/that myself.Although if i could get better ----I'll take it [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img].
I'll let you know about mine as i progress..
Kraky i didn't know the 7wsm was that close to the 7 rm , although my lee book shows 5.02cc and 5.27 for the rem-mag..I'm going to start loading for mine asap.-Mike
AIPAC for president !!!!!!!!!!!!!!!!!!!
A coworker of mine too the plunge to get a decient setup this year and got the A-bolt Stainless Stalker in 7WSM. Right out of the box the trigger was just over 6lbs , the bedding job is a joke and the recoil pad ain't much so with this setup and several differant quality factory loads the gun woulden't do much better than 1.5" at 100yds.
I rebedded the gun with Steel Bed , worked the trigger with a Timney spring kit and a little stoning and installed a Sims prefit recoil pad all this dropped the groups to just under 1" at 100yds. I recut the crown as it looked a little out of square (and was) and worked up a hand load using a 162gr A-max , match preped brass Federal 215M primers and 63grs of H-4831sc all gave a velocity of just under 3000 fps and accuracy is real close to the 1/2 moa mark out to 400yds. The recoil isin't that bad and the long A-max bucks the wind well and flattens deer.
The reloads are using once fired neck sized brass and the bullet is off the lands about .020" if I remember correctly. this load was worked up in a temp of about 80 degs and shows no sign of pressure in his gun but it did cause a sticky bolt when a buddy tried it in his Winchester so start a little lower and work you way up.
the Sims pad works realy well as does the Timney spring kit.
