I have a remington 700 action trued by Bob Brackney bedded into a mcmillan A5 with a 28 kreiger 1/10 twist chambered by Don Geraci in 300 WSM. True to the benchrest reputations of both smiths who worked on this gun it shoots just like my bench guns.
I am shooting 168 berger VLDs with a COAL of 2.860 and a slightly compressed load of 74.6gr of VV560 stuffed into win brass and fired off by Fed 215s. (I cant recall how much jam this is as I only recorded overall length but would guess that they are jammed .010) Velocity is a tad over 3200, but the accuracy is amazing.
Several 100 yard zeros, a couple of 300 yard .3s several 600 yard groups just a tad over 1 inch (all 3 shot groups) are credited to this gun, most from a bipod. It is easily the ugliest gun I own having been given the krylon treatment by the previous owner (including the NXS 5.5x22x56), but it shoots like a real beauty.

Here is my hunting load: A 168gr TSX seated over 71.0 grs of IMR 7828 with CCI Mag primers and Winchester Nickle Plated brass. I seat the bullet at 0.060" off the lands, the OCL runs 3.008", which is a little long for cycling out unspent rounds, but shoots .75 MOA when I do my part. The cycling problem only exists if I'm at the bench and don't want to chase a live round. If I work the bolt like in a hunting situation, it'll toss the unspent rounds with the best of them. The velocities run about 3,000 over my chrony at 10 feet. This velocity works well with my Leupold B&C reticle. I shot a cow elk at 280 yards last year. I used the 300 yard statia and hit both lungs. The TSX fully penetrated after it destroyed both lungs and the elk went about 5 yards before piling up.
The rifle is Kimber 8400 Montana. When I can get their custom shop to do a little work for me, I want to bevel and open up the ejection port a few thousands, and I'd love some bottom metal installed. I'll take the slight weight gain for another round and simplified loading and unloading.

I just completed load development for two 300WSM sporter weight rifles using 180 gr Accubonds. These are safe in my rifles, but work up carefully in yours.

Kimber 8400 300WSM, Leupold 4x14 30MM w/ varmint BDC reticle
Winchester brass, necks cleaned up to 14 thousands nominal, trim to 2.093"
Fed 210 Primers
69gr H4831sc
Nosler 180 gr Accubond seated at 2.86 oal
Groups (3/100) .5-.6, consistent w/a little vertical

Savage Sporter (24" large shank barrel, factory)Nikon Buckmasters 6-18x40 w/BDC reticle.
Federal brass, weight sorted, necks cleaned to 14 thou, 2.093"
Federal 210 primers
69.5gr H4831sc
Nosler 180 gr Accubond, seated 2.867"
Groups (3/100).3-.5, consistent, almost no vertical (best .154", .257")
In spite of the thick reticle, this one is shooting great for an inexpensive sporter.

I have these sighted 1.3" high at 100 yds and they are dead on at 200. Both loads work about the same with the 180gr NBT and shoot to almost the same POI. I set headspace on the Savage to the Kimber's dimensions (tight on a Kimber once-fired case) - reload with the same dies (Forster) set to 1.5 thou shoulder bump. Seems to be working - usually <1.5 thou TIR runout on finished rounds, measured 1/8" in from the composite tip.

I am having my Sako 75 300 WSM re-barreled to 7mm WSM and would like to use the Hornady 162 A-Max. The magazine will only allow an overall length of 74mm which will leave almost 9mm of projectile inside the case below the neck/shoulder juntion,(15mm inside the case in total). Can I expect this to cause any problems such as excess pressure.

In my 300 WSM load below, the base of the 180gr Accubond sits 5mm below the bottom of the shoulder. This load shoots extremely well with no signs of excess pressure evident.

Rifle: Remington 700 CDL, 26 inch fluted barrel

Load: 67grs W760, 180gr Accubond, Winchester brass, Federal 215 magnum primer.

I have a custom 300 WSM built by Richard Franklin. Its a Model 700 action with a Bartlein 30 inch 1:15 twist barrel with a .337 chamber throated for a 110 VMAX or 125 Nosler. My favorite load is the 110 VMAX pushed by 74.0 grains of N550 and a Federal 215M primer. This thing shoots like a PPC!!! and does a hell of a number on ground hogs.

Just tested with Win brass, RL 17, Fed 215 and the Barnes 168 TTSX (tipped).

67-69 grains MV started at 3216 and went to 3351.

ES and SD ranged from 41-3 and 23-1.

Accuracy was max .75 to a one hole.

Between 68 and 69 grains it was 10 down to 3 and 6 down to 1.

I am going to shoot 69.0 gr RL17, F215M, 168TTSX and my MV is 3351 with ES of 3 and SD of 1 for five shot group at .4 inches.

Used an Oehler 35 with 4 foot spacing of screens.

Tipped TSX:
