Accuracy data using Reloader 17 in Short Magnum cases?

[SJB358]

Thanks DF. Do you think a BR2 or CCI200 would have enough heat?

I use CCI200 and BR2 at various times in all my WSMs with good ignition.

Yes, I agree with Mike and I think DF will also confirm and especially the CCI200

My only concern would be hunting in cold weather which is what most of us use our WSM's for. Having had a bad experience with standard primers/varget in cold weather I think I would err to a magnum primer.

In Florida how cold does it get when hunting? I hunt at times in 5 - 25 degrees and never had an ignition problem with my 300WSM I use to hunt with and I used 210primers and then you add the powders not effected by cold weather much less the W760 that is suppose to be impacted by the cold and I was hunting in some mighty cold temps and humidity a year ago last fall at 19 degrees and no problems. I fail to see your point unless you had a bad primer which I also in 30 plus years have never experienced in the field hunting with my reloads or at the bench. Guess I am lucky. Did you have a bad lot of standard primers?

German Salazar wrote an excellent article in the Rifleman's Journal about primers. The article gave me an insight as to what type primer to use when developing load for a given cartridge. For example when I developed load for my 6.5-47 Lapua. I will be using a slow burning powder (H4350) to be ignited by a small primer. In this study, you can see that the Remington 9.5 has the most intensity of all the small primer tested and I happened to have 2000 on hand. It turned out to be a perfect choice. Just ordered 5000 of those babies. In looking at chart on small rifle primer, guess what I'm going to use for my 6BR... you've got it. Federal 205 Match.

WOW!! Thanks, great read indeed, very informative and enlightening, once again thank for those links. :grin:

Bullet, not in Florida. I deer hunt in Maine. The temps were -5 and the primer was a standard
WLR. I tested the load at my local range in Florida and fired roughly a box of ammo with no problems. I've shot the same load in Maine with WLRM and had no problems.

Maybe you compressed the primer to hard or something. Man, my heart would be broken ithe field and i missed a trophy because a primer failed, what a horrible thought. Glad it happened at the range and not when you where hunting.

Bullet, Some confusion I think I caused and should straighten out. I loaded up a box of ammo with WLR primers and varget and proceeded to sight my rifle in at my local rifle range just prior to heading to maine. I used most of the box up and loaded a second box the same way and took it as a backup. In Maine I used the ammo from my original sight-in box to hunt with. Again, the temps were -5. My shot came at roughly 9:30AM and yes, I did miss a really nice 8 pointer as I saw the bullet hit the gound underneath him. He didn't wait around for me to shoot again. When I fired there was a definite muted report. The following year I loaded up with the WLRM and Varget and had no further problems. It was actually somewhat colder the following year with temps around 10-12 below. I didn't get a shot at a deer but did shoot the rifle after 3-4 hours in the cold and didn't have any problems. As far as compressing the primer I don't feel I did.

big rifle man, sorry you missed that buck. I get the drift of your post. WOW, what a bummer!

Those WSM round seems to prefer slow burning powder. I use Reloader 25 on my 7 WSM and a standard rifle primer rather than magnums.

I don't know why I've always loaded these cases with the magnum primers, I suppose from looking at the manuals. Although years ago I did use the standard primer in the Galaxy, I'll load up the next 50 pieces with the 140 SMK that worked so well last week.... .2450"; .330", and .2660"; .3710" with the 140 SGK wasn't bad either. Those were three shot groups BTW. Not sure if I'll see a difference in those loads, they were all in perfect triangular groups for both loads.... not bad for a 9 lbs. Kimber Montana hunting gun!
