The wait begins

I’d make a dummy round with your 185’s about .030” shorter than mag length and have him throat it for that.  Will give you space to chase the lands and cycle well from your mag

I just talked to Shawn, very helpful and explained what he did. However I don’t see myself shooting 215’s ever so I will be dropping it off to have it throated for 185’s. I will make a dummy round before heading to his shop.

Thanks for all the helpful replies gents.

Goad hes gettin you fixed up. Those 185s are a good match for the wsm.

Yes I should have just went with my gut and have him throated for 185's from the get go but now I know. Big learning process for me.

Current WSM setup is a Wyatts long box and SAAMI chamber, 2.260" base to the ogive with 185s and h4831sc at 2995. You'll have lots of room for those 185s in that long box 

185s perform super nice. I've shot several big game animals from 30 yards to much, much farther and they haven't disappointed.

I was going to order a Wyatts long box but he suggested to use theirs so that's what I did. Are you able to feed from the top with the Wyatts box?

I'm hoping to get 3000 FPS or as close as possible to it with the 185's, h4831sc, and Fed 215M. I made a dummy round that had just enough clearance in the mag box before dropping the rifle back off at Defensive Edge so they will be throating the barrel to fit the dummy round.

No issues with loading the mag or feeding. I'm sure you'll be happy with what you get

Nice, but yes now that I got everything situated I'm pretty sure I will be happy with the final end results. Really on crunch time now to try and get this thing ready for modern rifle deer and elk season.

What’s a good starting point with h4831sc for this caliber? Berger doesn’t have it listed so I used Nosler as a reference. Getting sticky bolt at 66gr which was pretty low in Nosler’s book. Hodgdon doesn’t have it listed or their website besides h4831.


Obviously I need to start lower but don’t want to be too low. Trying to achieve 2900+ FPS

Hornady book shows 165 - 168 gr bullets at IMR 4831 starting at 60 gr for 2700 fps with 68.7 max load at 3100 fps. NO H4831 is shown for any load . H4350 starts at 57.8  and max's out at67.5gr with 2900 fps being 62.2gr.  Best I can do till later. I'll check Speer and Sierra when I get back tonight

with 185's at 66gr? What brass?

[Jonathan_S]

2900 shouldn't be an issue. Surprised if there are actual pressure signs at 66

[BULLBLASTER]

Are you in or near seating on the lands? Is there any excess head clearance?

Yes 185 Berger VLD hunting at 66gr with Hornady virgin brass. Using Fed 215M primer. Very sporadic. Some will shoot just fine and the next one will jam.

[jasnt]

I got load data from Berger for the 190 showing 66.5 as max. Should be good with 66 and 185’s.  Maybe more jump

[BULLBLASTER]

Try to back it off a bit for a firing and then size with minimal bump and then try working up in once fired brass.

I loaded 20 at 66gr to do barrel break in and to zero the scope. Some shot fine and some I couldn't even pull the bolt back to eject the brass. Velocity was only 2815.

[dmoua]

I'm 0.015" off the lands. I'll have to get my calipers to measure headspace. It's a head scratcher since at 66gr some shot just fine but some had stuck bolt issues.

I'm guessing more jump for less pressure?
