Wild One300 whizzum questions
Has anyone reloaded for this over here? I would be interested to hear anything about the blue meanies or loads with bullets heavier than 180 gr. Also where can I get a hold of brass ?
Thank you in advance for any help.....Dean

FjoldMine shows a marked preferance for Hornady 180 interlocks over the Speer Grand Slams. It also seems to like 4831 powder and magnum primers. I haven't tried any 200 grain or heavier bullets yet. Both MidSouth Shooters supply and Midway had new Winchester brass available.

ricciardelliWith all the new stuff on the market...is the "whizzum" the WSM or the WSSM?

KevinNYBrass is readily available from the various mail order houses. I have had good success with IMR4350 and Fed210 primers with the 180 grain Barnes TSX. 65.0 grains gives me 2900 fps and .45 MOA 3 shot groups every time. It's not max but it is accurate and consistent. Took 2 deer with it this fall both dropped in their tracks. I will be taking this load to africa in the spring. For anything needing heavier than 180 grain bullets I will be using my 35 Whelen. I would add that Redding full length/bushing dies with no neck expander are a key to my success with this cartridge, I fired cases 10 times with no problems with just one trim after the first 4 firings. Necks were spliting at 5 firings with Lee dies, overworked brass. Next year I will try to work with RE19 but right now I'm not changing a thing.

R-WESTI've had pretty good luck with W760 and 165 and 180 Hornady Spire Points. There was some discussion in here recently about whether or not magnum primers were needed - the general consensus was to use WLR's.
I've used Norma and W-W brass. The Norma brass is about 12 grains heavier than the W-W stuff; both are very consistent weight-wise and excellent quality.
I HAVE had some strange case extraction problems. Using either new or once fired, neck-sized (Redding) brass, and moderate loads (3050 FPS with 66 W760 and 165's in the M70's 24" barrel, as a for instance, but there are other moderate ones with R19 and H4350 that do the same thing), I'm experiencing very hard bolt lift. Those loads are nowhere near max
Still trying to figure that one out.

Wild OneThank you guys....
R-west ..I also noticed a very tight bolt fit at lock down,
any ideas on what that could be from?
I took 2 deer and a caribou with mine this year with the 180 failsafes ( factory stuff ) . The 2 deer were killed within 25 yards so not much preformance to go by on those but the bou was at 255 . I must say this it didn't make em' any deader than my 280 or 7 rem , not overly excited. I only got because I was in Griz country on the bou hunt and yes I did see one hell of a bear .

KevinNYThe tight bolt lock down and lift may be from an out of round chamber. Mine was so egg shaped from the factory that a full length resized case would not chamber at all. I sent it back and they set the barrel back and recut the chamber.

R-WESTHi KevinNY. Was the egg-shaped chamber visually apparent by inspection of the fired cases? I've looked mine over very carefully and don't
see anything, but, we're probably only talking a few thousandths as enough to cause problems.

R-WESTHey Wild One. Sorry, with this goofy new forum, you can't see all the prior posts, only the one you pick out to reply to.
In any event, I've seen other posts about tight bolt closing, with either new or neck sized cases, but, IIRC, that was a 7WSM. That poster mentioned curing the problem by FL sizing the cases. I hadn't really noticed a problem on closing the bolt until this past Sunday when I tried some new loads in once fired, neck sized W-W cases. I guess that could also be caused by an out of round chamber, like KevinNY noted.
Sure seems weird that so many guys would have case problems with the same caliber, or case style, doesn't it? How could they have that many egg shaped chambers? Maybe it was just one machine or something that was out of spec, and only a few got through like that (and, lucky us, we got 'em
). I just don't know. I do know that the next stop for the rifle is a competent smith to check out the chamber.

KevinNYIf you roll a fired case across a very flat surface like a granite countertop you can detect an out of round case. There are tools to measure concentricity as well.

cliffs2I have trouble with my 270 wsm A bolt too. Same thing, bolt closes hard the last push down. Also opens hard. Not that it jams but it is distracting. I use Lee full length dies and it does not happen with new brass or factory loads. I do not use these for hunting as I am afraid the bolt will not fully close on a follow up shot. I only use new brass for hunting loads.
I'm in the low rent district, all my countertops are plastic laminate
