Read 4350 was the powder for 260 Rem. I got IMR rather than Hodgons. Big mistake

[Danattherock]

Read an article someone here linked last week. Basically it showed what all the top long range precision guys were using. The powder of choice was 4350. I had used IMR-4350 in past with sub MOA 300 Wby load. Plan on buying a 260 soon for some fairly local competitions and largely justified buying more 4350 for that reason as I have 6 lbs already for the 300 Wby. At the gun show this morning I found and bought an 8 lb jug of IMR-4350. Afterwards, my buddy tells me I bought the wrong powder and I should have bought H4350 for the soon to be 260 Rem target rifle. I had sent him a link to the previously mentioned article. Did I buy the wrong powder? Either way, I'm not telling the wife. Ha ha.

IMR-4350 will work for the 260 rem and most other similar ballistic cartridges like the 6.5 creedmoor, and 6.5x47 Lapua.

That said, almost everyone I know uses H4350. Some even use H4831SC with long drop tubes.

IMR-4350 will probably be a little more temp sensitive so if you can help it, watch out if you start loading near max charges in your gun with IMR 4350. IMR4350 also tends to give a little more velocity than H4350.

good luck.

Thanks. Guess I need to learn how to read. Here is a link to the article I kinda read.

I loaded up some IMR 4350 and some H4350 a while back. Not much difference. I can't remember which one was slower or faster but it was maybe 10 fps out of an old lot IMR VS new Lot H. I have seen more variation than that from lot to lot. The cut on the H is a little shorter and easier to meter, and of course there is the temp thing, maybe. I would just run it and be happy. With luck, by the time you run out, H4350 might be a little easier to find.

MY 6.5 CREEDMOOR AND 6.5X47 LAPUA SURE LIKES H-4350 BETTER IN MY RIFLES

Might I mention, there is also an Accurate 4350.

My Ford will out run your Chevy. No my Chevy will out run your Ford. Same with IMR and H or even AA 4350. Might be a little difference in the load but they all will shoot great.

Looking at the link that Dan supplied I notice that there is a big difference in bullets that are used in tactical competition vs. prone competition, mainly the lack of Sierras. I know Berger is a great bullet but is it a sponsorship thing, mag length thing or accuracy? Opinions?

 

[Ringostar]

I believe the lack of Sierra bullets, can be related to the lack of availability, during the last couple years. I like the Sierra 142's in my 260, but have a hard time finding them. I can get Berger 140 hybrids easier.

Thanks guys. Looks like I got a good stash of 300 Wby powder ;D

Will need to load the butt with split shot and slap a limbsaver pad on it if I am going to shoot it this much. Heck, I need to buy another stock for this Wby Vanguard, it's got a cheapy. The rifle is very lightweight and far more punishing than my 50 bmg. A buddy worked up a 5/8" capable load with it years ago. It was 4350 and 168 amax. Had a very hard time finding that bullet this past year since getting into reloading.

But a few nights back got lucky on Cabelas and found 250 packs on sale for $59/each with free shipping. I bought 1,000 and at the time thought I overdid it. Now that I got 14 lbs of 4350, perhaps not. Doing math on 80 grains per round, I got 1250 charges, to go with my total of 1150 bullets. Time to make some lemonade out of lemons.

Unfortunately the long range shooting events I am interested in allow 300 win mag at a max, but I will have fun shooting my 300 Wby recreationally on the same ranges. I need to improve my skillset anyway. By the time I shoot 1150 rounds, maybe I will be able to more easily justify purchasing the Savage LRP Model 12 with Bushnell 3.5-21 GAP I been lusting over. Anyway, I need to go find some split shot.

Thanks for your insights, as always.

By the time you shoot 1150 rounds in a 300 Weatherby the barrel is going to be gone and need replacing. Depending on your accuracy requirements and how hot the barrel gets when shooting, it may only take 800-900.

 

[Danattherock]

Either way, aside from a few lever actions, it's the only rifle I own between my AR15's and 50 BMG. Got to start somewhere I guess. I would love to put a heavy barrel on this Howa action anyway. It's a real shooter for around $500 as I recall, about 15 year old Walmart impulse buy. I don't even hunt. Ha ha.
