i completely agree bd, you not only would see an increase in speed but case pressure as well and more importantly in my eyes. If you do make the switch id recommend starting below the published min a grain or so and then work back up slowly.

From my understanding and it is not much of anything at all ever... The mag primer will burn more powder faster (from the start) and make pressure shoot up faster than a LR primer will.

I am going to test the CFE223 loads that I have loaded with LR primers first, then if those don't give me the results I want I will try the Accubonds with IMR4350. If that doesn't work, then I will start working with the Hornady 139 gr BTSP I have, have less than 50 of the Accubonds left.

I would stick with standard large rifle primers; maybe mags with 760. I am not sure why you use bonded bullets for deer? Any cup and core will work just fine and cheaper. Start with .025" off the lands and go from there for seating depth.If you have a bolt gun, resize only .003...

I was trying Accubonds because of past experience with them in my 308.  Thanks for the advice, the rifle in question will not shoot the Accubonds so I have started testing the Hornady BTSP.

It shoots factory Remington 140 cor-lokts into 1 inch or less at 100 yards, haven't tried any Sierra's yet, but I had a bad experience with the 6.8 Pro-Hunter's (5 jacket separations on 5 deer) so I have stayed away from them.  Once the kids go back to school I will be able to test the Hornady BTSP and if they don't work I will try something else.

ive killed a ton of deer with them, cant complain. I shot one cow elk with my 30-06 when i was in high school, no problem. My dad has used them since the 70's. I love the prohunters. I havent met a gun yet that wont shoot sierras.

If I can't get the Hornady's to work I will try the prohunters, I just may have gotten a bad batch.  The rifle has shot multiple brands of factory ammo well, that is why I have waited so long to reload for it.

I shoot Berger 168 VLD hunting bullets from mine. 39 grains of R-15. My max length that will feed reliably from the magazine is 2.800. This load is accurate and the velocity is 2560 fps. Start lower of course, that load is slightly over max. You'll also get some meat damage with the VLDs.

With that limited powder capacity I would stick with 120-140's....

Other than reduced recoil, I see no advantage in shooting the lighter bullets. H4350 is likely a better powder for the 168s but wasn't as accurate for me.

The advantage is going to be with much easier wind calls down range. Not necessarily a huge difference at 2-300 hunting distances, but if you shoot further than that it adds up in a hurry!

If it is tourist season, why can't we shoot them?

The high ballistic coefficient of the 7mm 168 gr VLD bullet, actually makes it drift LESS in the wind. It will also retain more energy. You can calculate wind drift, retained energy and bullet drop here:

My fault. Guess I'm a little dense.

Have you tried the 180 grain? Tempted to give them a shot (shot, get it?) but I'm doubting if I can get them short enough to fit in my magazine.

I was poking around yesterday and did notice that Barnes is now making a 145gr LRX in 7mm.  I load the 175gr LRX in my 300WM, and they seem to do very well.  I'm thinking of loading some for my 7mm-08 Featherweight this year.  It's listed as .486BC and .257 S.D.
