Anybody with experience using factory "Match" .300 Winchester Magnum ammunition.

Any preferences or experiences welcomed.

I do hand load just the pipeline at the bench is backing up.

Likely use rocks, with a little luck the Rock Chuck calling said rock home.
 
Candy store! Good link Thank You! I tried to find them with Google and HSM yesterday and could not get in. The IQ metals went right there.

They were out of the A-MAX, probably for the best, I've been on a binge lately. I'll have one of these and one of these, please.

They have 5 boxes of 168 left, trying not to buy all 5 until I know they shoot in the rifle. No need cornering the market.
 
i've got 4 boxes to work with, 150 managed recoil, 168, 185, and a 185 light. I'll try the 178 A-Max in the next round if one of these doesn't distinguish itself. Thanks for the help.
 
Last summer I had a custom rig built for an employee of mine. Defiance Deviant, Obermeyer, AIAX chassis...etc

He doesn't reload so I set him up with the Federal Match ammo, 190 SMK's. It hammers with the FGMM, the 190 may not be the best bullet choice for ELR but, anything inside~1200 should be shaking in it's boots.

Thanks,
I'll try the 190's in the next round. It looks like there are some good bullets being loaded. When they're in stock anyway.

I'll eventually load my own, I have a full bench right now, and with a little luck some variety in small batches will provide some direction, as well as a bit of brass.

I have a 1 in 10 twist on my 300win mag and had real good results with Black Hills Gold match with 190gr SMK's I bought 4 boxes of Black Hills and 1 box of Federal Match with 190gr when I first got it. But my rifle liked the Black Hills a little better I believe.
The heavier bullets did better than any of the lighter ones I bought to try, just seemed to be what my rifle liked. I reload now with nothing but 190gr to 215 gr bullets and have been very happy.

Did you experiment with overall length when you went to re-loading? If so how much longer are the re-loads vs factory? Thank You!

I know it's not addressed to me but I happen to have pix handy I used to respond to a similar thread.

Factory load are normally 3.34" (base to tip). This is one of my load (200gr NAB) for my SAKOM995 (DBM) in .300 Win Mag ...

My Savage 111F in .300 Win Mag (staggered internal mag) can only handle 3.48" with the same bullet without any feeding problem.
 
Thanks Feenix,

Almost to the decimal what I'm finding.

I have 3.66" magazine length, pulled the bullets for reseat, but with the Berger 168-and 185's it's right at fall out length.

In this CRF Montana the mis alignment (run out)after cycling through the action is visible.

They consistently shoot into an inch, but I've been shooting 2 touching, and one out all week. Convinced that flyer is run-out and bullet jump for now.

I've only got a handful of 200 Accubonds left, but I've got enough little of this and that, from days bygone. I've got some old Barnes Originals 225 spritzers that have taken space on the shelf long enough-they go next. Plenty of bearing surface in and out of the the case.
Thanks

Yes I did experiment with length, and it does make a big difference. I measure the length of my loaded rounds from the base to the Ogave now no matter the type bullet for all my loads. I may check the over all length every now and then but the length to the Ogave is the main measurement I use.
I measure the distance to the lands from the base to the Ogave on a bullet and worked from that, I've found that seating the bullets from .015 to .060 or so off the lands to the Ogave depending on bullet type has been the best for my rifle.
Each rifle will be "different" so the over all length one can use will vary according to each rifle, it will take a little fooling with to find your sweet spot. What worked in someone else's rifle may not work in yours.
I have a AI detachable magazine that has plenty of room for anything I've loaded. It will take and load what ever I've put in in so far, and I do get way out there on over all length with some bullets. Not all magazines will be able to use long loads so that may be what determines how long you can get by with.
When in doubt and you have no way of measuring to the Ogave I would stick with SAAMI spec's for length and you cant go wrong. You for sure want to avoid jamming a load by having it to long.
I hope this may help you instead of confuse you, have a good'n

Some say confusion is my natural state. Getting set up to measure from the Ogive is nearing the top of my list.

I did have to clean up some powder, and remove a bullet with a cleaning rod. Always pays to check before you go the range.:D

Would you say the .3 range such as Feenix and I are seeing is similar to what you're finding also?
