No, no that won't do. We'll need an article that really gets to the crux of some serious rifle issues, like why a 280 case necked to 277 caliber will out perform the standard 270, due to increased case capacity, or the correct way to attach sling swivels to counter the rotational torque of a right hand twist, or the statistical probability of a bolt handle coming off when you are being charged by a grassland wolverine in eastern Montana.
And when you are done that article, I'd be quite content to have more mundane articles like the old ones that have been worth saving. The ones like you favorite loads and the update, the article about rodent rifles, factors of accuracy.

Ok, I suppose I can crank out some boring articles about things like handloads that work, but your idea about the prairie wolverines is more intriguing. I have only shot one wolverine in my life, and that was with a break-action single-shot rifle, so have no experience with bolt handles coming off when wolverines charge. Guess I'll have to go out and find a good wolverine town and shoot a few more.

Wow! Great news, John. Everyone was "greatly distressed" about your rift with Wolfe. I called and added my two cents, for what that was worth. Let's leave it at I'm very glad your back writing where I can find you.

GREAT news!! I'm looking forward to reading you again in "Rifle" and "Handloader". IMHO they are THE two best shooting mags in print. You, Brian Pearce and Mike Venturino are ALWAYS interesting and informative to read. Brian sold me on the .45 Colt and you confirmed my use of a hunting MV of 2700 FPS, it just flat works. Keep up the good work and thanks for keeping it interesting and fresh. I, and I'm sure I speak for the other readers, really appreciate the hard work that you guys do in order to meet deadlines each month.
Thanks again,
Hal

Hi JB,
Just got back from testing some loads in my Rem. pump, '06. I partial re-sized, as in your article. An elder gentleman said that he thought cartridges for pumps should be fully resized.

So.... Partial, or Full sizing on my previously fired brass in my Rem. 7600, pump??

Thanks!! Ken

Ok I like the weatherby also, however, it is not best 30 cal magnum by a long shot. The only advantage it has over the 300 WSM is the ability to push the heavier bullets.

For example it was quoted that the writers weatherby runs the 168 Barnes TTSX at 3269 fps into a 1.5" group using 90 plus grains of powder. Well my 26" 300 WSM happens to run the same 168 TTSX at 3253 into .5 inches and in a much lighter short action gun using 60 plus grains of powder. That is measured over a Oehler 35 with 8ft screen spacing and multiple measurements so no fluke.

So basically same MV for 1/3rd less powder. Now thats efficiancy!

I shoot LR BR and have used both the 300 Weatherby and the 300 WSM. Both are great shooters and very close in accuracy and MV. We routinely run 210 JLK and Bergers at 2950-3000 fps in the WSM. Now the Weatherby will run them 3050-3100 tops.

Plus, mosty importantly I get 2-4x the barrel life in a WSM. Danny Brooks 2008 Shooter of the Year for 1k in IBS won with a WSM that had 4000 rounds in it at the end of the Nationals. NO other 30 cal magnum has ever done that. My first barrel had over 2600 rds before I pulled it and still winning. My weatherby barrels were toast at 1200 rounds max.

Once again the WSM is more efficiant cost wise in components and barrel life.

Is the 300 Weatherby the best magnum, not IMO but still very good.

John,
Check out the July issue of Rifle, especially 'Straight Talk' by Ron Spomer. He really GOOF on the 6.8 SPC big time!! He said it's a "necked up .223 Remington case", and puts little value in the 115 gr. bullet for deer. Read the article for yourself, you have hands on experience with the 6.8 and know what it will do. We're still waiting for your article on the 6.8X43!!!

JB, I'm new to the campfire so maybe I have missed the topic. What are your thoughts on the 223 and 22-250 for deer and lopes?

MD--Bear with me, I know practically nothing about reloading--but I'm curious about a couple of things. I've used the Hornady light mags and thought they were agood round--now they've come out with the "Superformance" ammo. It appears to be about the same as the light-mag without the additional recoil(from what I've read--have not tried them yet). I'm curious in two ways 1) if I pulled the sst bullet out of the super round and substituted a tougher bullet of the same shape and weight--would the bullet perform the same,(mv, energy, traj , etc.) 2) what would be the inherant problems if I stuck in a lighter bullet ( pull a 140g 270 and replace with a 110g 270)? Thanks--Bill

If you have the reloading equipment that will allow you to start substituting components why are you not developing your own loads? At your level of experience I don't think it would be wise to start experimenting on your own. For example, in your second question about substituting lighter bullets the powder in the case may not be well suited to the lighter weight of bullet. It might work, but then again it might not and if so, what have you gotten for your efforts?

I think you have to make a choice. Either stick to factory ammo or else get into reloading, read and understand the manuals and develope the experience to tune ammo to your gun.

Just remember, the advice may be worth just what you paid for it. smile

I read with interest the comments regarding the .257 and .300 Weatherby, several years ago i borrowed a friend's .257WM to deer hunt with and found it to be a really nice rifle and cartridge. Can't say the same thing about the .300WM, that rifle was just plain ornery and kicked the snot out of me every time I squeezed the trigger. My elk rifle is a pre '64 Winchester M/70 which I regularly shoot 275gr. handloads with wo I am acquainted with rifles that kick hard. That .300WM had recoil that I just found to be untolerable, the guy that it belonged to used to get a bloody lip from the thing ramming his thumb into his lip just about every time he fired it. Not my idea of an ideal rifle by a long shot.

My intent is not to offend anyone, but a legitimate [to me at least] question. What is the advantage of a fast twist [1in8] 22 centerfire...223, .223AI,etc.? I fully understand it allows one to shoot heavier bullets [longer bearing surface] I certainly enjoy the .22 centerfire [I have and shoot/hunt with, .204, .222, 22-250, 22-250AI] However, I've always shot lighter bullets...typically 36gr, 53gr for coyotes, 53gr TSX,60gr. NPT's for deer or perhaps longer distances. If I want to shoot heavier bullets, i.e., 70 to 80gr. I shoot a 6mm Rem, .25 WSSM [HORRORS] My 6mm is a Ruger #1 and a 26" barrel and will shoot 75gr bullets pretty fast and is accurate enough to hit a coyote @ 400yds if it's not too windy and I manage to do my part. Are the fast twist .22's an economy issue? a recoil issue? a noise issue? Again this is not an argument..maybe I need a fast twist .22 centerfire? Thanks for advice and council. I might add, the very best reason to own/shoot a cartdrige is just because we like it.

The advantage to shooting heavier bullets for a given caliber is a higher ballistic coefficient. This doesn't always equate to a flatter trajectory, as velocity will be reduced, but it seems to help considerably with wind-drift. I also like 22 center fires, particularly the .22 BR, and there is no comparing the wind-drift of a typical 50 grain bullet to that of an 80 grainer fired from it.

John,

I have a lot of respect for your opinions based on your practical and knowledgeable posts that I've read since joining the campfire. As pertaining to this topic, I've hunted deer most of my life and admittedly, I'm smitten with Whitetail (any deer) hunting. I love the challenge of hunting a mature buck who kicks my azz most of the time. I cut my teeth on 270 wins and 30-06's. In the past 5 years, I've come to enjoy more moderate calibers for deer such as, 6.5x55, 7mm-08, 7x57. Partly, because they're more fun to shoot and I enjoy the challenge "of catching larger fish on reasonable lighter tackle" but also, I want my young son who has the hunting bug to start out with effective calibers that he can handle and learn good shooting technique. Currently, I'm on a 6.5x55, 7mm-08 and 7x57 kick and have a few rifles in each. I'll hunt with them, learn about their effectiveness and ultimately weed a few out to make room for a few other interesting calibers. I'm interested in your opinion on 257 Roberts versus 25-06 (already know about the limited availability of factory ammo for the 257, I currently don't reload but have access) or any other recommendations that you have. Thanks for your time.

MCT3,

Thanks for the kind comments.

In my experience, the .257 Roberts is just as effective at killing whitetails as any of the rounds you mention.
