Are the C/T (Winchester-Nosler) Partitions any better than the original Nosler Partition

Hi Greg--
According to Nosler, the Partition Gold is designed for higher weight retention (80% v. 66-70%) and slower expansion. This is accomplished by moving the partition further forward and increasing the jacket taper (so the jacket is heavier at the midsection). It is still supposed to mushroom reliably at lower impact velocities.
The moly coating may or may not reduce pressures depending on your individual barrel. Am not sure if the steel cup in the rear core is good or bad--I have always believed that 'beer-kegging' was a positive thing (as with Swift A-frames).
While I have a fair bit of experience with the standard partition I have not used the CT Golds. Maybe someone with first-hand experience can tell you if they actually work as advertised, although judging from my experience with Nosler I don't know why they wouldn't.

Gettin' ready for the 338-08

Just got the word from the builder, the 338-08 will be shipped within 10 days. Scoped weight will be under 6 lbs. w/21" bbl.
My plan is to use two bullet weights, 180 BTip and 225 controlled expansion types. For starters I'll develop a max. pressure limit with 200 gr. bullets using 3 or 4 powders. Once I find the max with 200's. I'll be able to extrapolate to 180's and 225's fairly easily..
Any suggestions on powders? I'd think that powders would be similar to .358 exccept that the best powders would work for the next lowest weight in the 338-08. IE: if the best powder for a .358 250 gr. bullet were found to be 4198, then that might turn out to be the best for the 338-08 with 225's.
So......As I start to develop pressure limits, any suggestions on the 3 or 4 powders to choose??
I'm guessing @ 4198 on the fast side, and 748 on the slow side. Any specific suggestions???

JF--  Remember our good-natured wrangling over the 358 versus your wildcat 338/08? Now, of course, I'm keenly interested in how your project turns out. And still interested in myself doing the "next", obvious, wildcat: a 375/08. Someday. Keep the reports coming in. I'll have to admit you have a hell of a ramblin' caliber coming out of the chute there.

Patrick , Of course, I'll keep the updates coming. We just got 2 feet of snow, so the "range" won't be acessible for a while yet. Actually, trying to load, shoot, set up and take down the chrono etc. with only one hand, (lefty no less) may be more hassle than it's worth. I can't wait to see and feel the new gun, but it's prob'ly just as well to wait until I have two hands working again before I start shooting.

7mm mag. handload

I just completed load development for a 175 grain nosler partition semi-spitzer in the 7 mag. The load consists of 62.5 grains of Reloader 22 in a winchester case, ignited with a Federal 215 primer. Does anyone have experience with a similiar load? I know every rifle is different, but I'm interested in how it compares to what others have done. Please comment guys. John in Texas.

Comments: John,
Ive done quite a bit of loading for the 7 mag., but with 160gr. bullets. However, I noticed the use of the Fed 215 Primer in your data. Aliant reccomends the use of only standard, not mag. primers to ignite their powder. Ive found better accuracy from the use of Fed 210's than I have from 215's GENERALY when using Reloader 22 and 19. Just a thought. Have fun. TimRe: 7mm mag. handload

Comments:: Thanks for your comments about Federal 210 primers. I'll give them a try. It's interesting that you mentioned Alliant recommending standard primers. When I went to their web site, they listed their load for 175 grain bullets with 215. That's why I chose to use the magnum primer. The 210's are listed for the 160 grain loads. Do you think bullet weight may be the deciding factor in primer selection?Re: 7mm mag. handload

Comments: Mr. Sundles, Just another thank you. I'll have to try standard primers with Reloder 19 and 22, I've always used the magnum primers, too. -DanRe: 7mm mag. handload

Comments: Try 72 grains of H1000 behind the hornady or speer grand slam bullet with the remington mag primer. I shoot 5 shot groups you can cover with a quarter with both these loads. I've gone to 175 grain bullets exclusively in my 7 mag because I can't get a really noticable increase in horsepower over my .280 with the 7 mag unless I shoot the heavier bullets. Go heavy for the elk! Good hunting...Re: 7mm mag. handload

Comments: Wyomoke. Facinating load. Thanks for sharing it. What type of rifle are you using and which supplier of brass do you use? Do you notice any fluctuations with extreme temperature changes. In Texas it's not unusual to work up a load in 90 degree summer weather and hunt when the temperature is in the 20's. I try to avoid load development when the temp is cold. In Texas, we are more than likely to hunt when the weather is warm rather than cold. I've had IMR 4350 heat up on me to the point of a locked bolt. Ten minutes earlier I was shooting the load in the shade with no problems. It was quite an eye opener. Thanks again for your comments. John in TexasRe: 7mm mag. handload

Comments: Ruger M-77 (old tang safety model, I bought new right out of high school in Nevada for $144.00!)and Hornady Frontier brass. Had a coffee can full from ammo I shot prior to becoming a reloader. As far as pressure fluctuations, I have never shot it in hot weather. That is a max load from manuals, but I have shot up to 74 grains of H1000 with no high pressure apparent.

Comments: One frustration in life is that things keep changing. Just when you have learned something, a manufacturer changes ingredients or recomendations, etc.. In the beginning, Aliant stated not to use any mag primers with their powders period. Now I hear that some of their data shows Fed. 215's being used!
In my experience with Reloader 19 and 22, I got significant acuraccy improvemnts when I went from the fed 215 to the Fed 210. However, each rifle and load has its own mind and I wouldnt be suprised if my experience did not translate over to every one else 100%.
