Re: Load Workup Q? on 300wm

reeladmin: none taken! CPX is a Class system that I think Winchester started to describe the size of Game... my apologies, I thought it was used a little more regularly. CPX-2 is deer-sized game and CPX-3 is Elk-size. I'll be hunting both whitetail and (hopefully) Elk.

I'll start with one bullet then, and find a nice recipe


Trnelson: I'd really like to try them. Will the same weight work with both deer and elk, or go with different weights?

Grumulkin: man that's a good shooting setup! I'm surprised about the tips coming off, though...have a lot of people had the same problem?

Thanks again, all!

IMO, I would pick one or the other and not simultaneously work on both. The probability of both bullets having the same POI is slim and none. Either of those bullets will be strong medicine for deer or elk. Personally I would go with the 210 and it's better BC which will give you less drop and less wind drift. At 5-600 yards, IMHO, that could be the difference between a freezer full of meat and a clean miss, or a wounded but unrecovered animal. I use the 230g Berger tactical OTM personally in my 30/338 winchester. I run it right about 2,800fps, it prints 1/2 MOA for me. I have been considering the 210g Berger vld hunting bullet as it matches or betters the 230g I'm currently loading out to 700 and frankly I've never had the need to shoot beyond 500 while hunting. That being said, I have personally always gravitated to the best BC bullet I could get my hands on and the .711 of the 230g tactical OTM is hard to ignore. I worked on the 240g Sierra MK but just couldn't get it to shoot even MOA out of my 26" 10 twist tube. I just don't think I could shoot it with enough velocity to fully stabilize the 240 SMK. The hotter I shot it the better it printed for me, I just ran into pressure before I got where I wanted as far as accuracy is concerned. With the case volume of the 300wm you may be able to find great accuracy provided you have at least a 10 twist barrel, and a 9 would be ideal for the big SMK. Velocity is a nice thing to have but accuracy is irreplaceable.

Re: Load Workup Q? on 300wm

If you can't get a Nosler accubond or Partition to shoot with Imr 4350 or H4831sc in decent brass with standard primers (CCI BR2s Fed210Ms etc..) then you shouldn't even waste money on berger bullets until your loading skills are honed in. Noslers are probably the most forgiving with seating depth, neck tension, bad case prep, etc.., Sierra MKs are also but most will say do not use those for hunting.

Re: Load Workup Q? on 300wm

I think that's what I'll aim for then, one bullet at a time.

The 230gr VLDs do look awesome. Do you think the 300wm has the git up 'n go for that bullet? If so I might play with it them after the freezer is full.

As for the reloading, I've got about 100 Winchester fire-formed brass that I'm going to neck turn, neck size (lee collet) and uniform the primer pocket in and out. I just need a good tool for that, don't have one yet. The BR2 from CCI seems to come up quite a bit so I'll give them a good try, as long as it gets along with the powder. Haven't decided if I'm going to mess with the runout gauge yet.

Hopefully this will get me on the right track.

Oh, and ordered a McMillian A3 from Len today the wife didn't even divorce me . Today's a good day

Re: Load Workup Q? on 300wm

I'm not sure what your barrel length and twist are, but if I were going to shoot the 230 OTM I would want atleast a 26" 10 twist, even better with a 28-30" to break 2800fps a lot easier, but since there isn't a huge difference between the 215 and 230 OTM bc wise, i'd stick with the 215 as the heaviest in a win mag. Winchester brass is tough and last a good while but for best results it should be weight sorted. Also no need to turn the necks unless you have a tight neck chamber, and by your post mentioning a Lee collet die I'm guessing you do not. Just clean the necks up with 4 ought steel wool or 600 grit sand paper. I would also steer clear of the collet die and get a Redding type S. For your game and distance selection, the 180 BT or accubond will do the job just fine with Imr4350 and BR2 primerrs and should break 3K fps with a low ES.

Re: Load Workup Q? on 300wm

Based on your questions re: load development and bullet performance on game, I assume you are new to the sport. If not I apologize.
My advice, don't get caught up in the long range thing until you get considerably more expierance under your belt. Pick a good HUNTING bullet designed for the largest game you plan to hunt and use it for everything. Better to be over-gunned for the deer than be under-gunned on Elk, Moose. A good controlled expansion 180 gr will do fine. You don't need a VLD unless shooting at LONG ranges.

Start with your chosen bullet, and two of the most often listed powders in the manuals. 4350 and 4831 were already mentioned. Load three rounds of each powder at the "average" starting load listed in the manuals. Increase the charge weight by 1/2 grain and load 3 more of each powder. (Don't change any other variables). Continue increasing the loads by 1/2 gr until you reach the max listed, or you reach max pres/velocity in your rifle.

Once that is done, analize all the targets and you should have at least one that is noticably tighter than the rest. Now load more exactly the same as your best group and varify it was'nt a fluke. If you still want to improve on that, play with seating depth, then primers to fine tune it. If none of those work for you, try another bullet, and/or powder and start over. And all the while you will be gaining knowledge and getting more trigger time.

Focus on becoming a good hunter/shooter and the rest will fall into place.
remember the rule KISS.
And Have fun

Re: Load Workup Q? on 300wm

Yup, that's right kermodie, new to the long range thing. I've Shot a bunch of 3 & 4-position smallbore, but not long-range and haven't reloaded for rifle yet.

My plan was find a load that works and then proceed to wear out the barrel learning how to make it all come together. I'm pretty comfortable with the rifle out to 400 yards on deer, a four-inch group no problem. The two whitetails I took with it were both close-in though, so I'll probably have to get stationed back out West before I'll get some real-life practice. But can't wait to get busy wearing out that barrel!

backwoods83: yeah, you're right, I've got a 26" bbl w/ a 10 twist now so the super-heavies probably aren't in the cards for me with this rifle. Yet. Probably won't mess with the VLDs until I can shoot long enough for them to make a difference, like kermodie said.

You mentioned not needing to turn the necks unless I have a tight chamber, just curious why that is? I have no idea how tight it is, it's a stock chamber in a 700 5r, so I assume it's on the loose end.

Thanks for the help on how to find the right load!

Cheers!
Chris
