300 Weatherby advice

[Lastgun]

Like you said in your opening post...I load up 180 grain Nosler partitions with a stiff charge of IMR7828 for my brother's Weatherby 300 in a Sako L691...Shoots very accurate...I have seen him shoot crows at range with it just to show he could.

I crimp all my rounds and in this case it did not really seem to overcome the Weatherby free bore. Today I shot the previously trialed 178 and 200 grain ELD-X bullets in my 3006 Sauer 101 just short of the rifling and they shot perfectly moa without much effort so it's clear that free bore is the issue not the bullet. As suggested I also tried 150 grain interlocks in the 300 bee and they shot moa. Hornady SSTs were ok at 2 inch groups and possibly could be tuned a bit more but it seems the obvious winner in my rifle is 180 grains partitions with 7828 powder ( 200 grain would probably be fine too). Dang I wish these projectiles were not so pricey... I guess its like the guy with a fancy pants car complaining about the price of premium unleaded. It is what it is or maybe not, I still have not tried some hard cast gas checked bullets I made a while back. Assuming it does not lead the barrel up too bad and if I could get at least 3 inch groups it I might consider this a decent plinking round. Hmm, stay tuned this might be fun trying to push a cast gas checked bullet at 2000+ ft per second. 3000 ft per sec is probably unreasonable to expect but I will probably try it and see

Maybe look into Woodleigh bullets? Similar shape to the partition, but they're bonded AND cost less. On game results are exactly what you'd look for, good expansion and high weight retention.

Tradex has 180 and 220gr varieties for $44 a box of 50.

Has anyone ever tried the long range accubond in the 300 wby? It seems to be a fairly streamlined bullet with good intentions.

I'd be surprised if you could get them to shoot. On the other hand the 190 LR is one of my favorite bullets in the .300 Win. One that I use it in is a Mark V rebarrelled to .300 Win. Its great if you want a viciously expanding/fragmenting game bullet for zero- to 1000 that laughs at wind.
