Looking for some rough velocity numbers for a 300 wsm and a 215 Berger out of a 22” barrel. I have h4350, R26 and N565 to work with. Is 2870-2900 an unobtainable number? Shot a lot of wsm barrels, but all 32” fclass rigs so just trying to gauge where I’ll be at.

I don't think it's doable without wrecking brass. F-class guys shooting the 300 wsm are getting about 2850 from 30" barrels and just north of 2,900 fps with the 215's in 32" barrels. That said these velocities are with single-base powders. 22" on a 300 wsm just seems like you are going to burn a lot powder outside of the barrel regardless.

I'm in the process of building a 300 wsm f-class rig and am going with a 33" 9.5 twist to shoot the 215's.

You can not reliably get over 2850 with a 22 inch barrel regardless of the powder. I am seeing 2900-2950 with RL26, just shy of 2900 with N565 and 2850-2880 with RL23. Those are all with a 26" barrel. H4350 will most likely be around 250 fps slower than your flclass rigs.

Sounds like 2780-2800 may be more of a realistic number, especially with N565. Only reason for going short is trying to not have this be as long as my fclass rigs with a 5” can on it. Trying to stay with a 215 if I can but it may be beneficial to go down to the 200.20x or the 200 Hybrid

I will never understand the can craze. I try my best to help but I don't get it. My time, money, and tags are far too important to give up 100fps in any given cartridge just to avoid plugging up for one shot. On the range they make even less sense because I always wear plugs.

This is my first year with a can, right now I’m shooting a 284 Shehane hunting rig with 184’s at 2910 in a 26” barrel. I’m still not sure I’m sold on the can, still on the fence. Until now I had a 3 or 4 port brake to track impacts. But a 31” total barrel with a can was awful to wield around this year in some thick timber.

Ya, I like them long but not 31". LOL. I would love it if you would start a thread talking about your Shehane. I am considering building one for hunting.

Happy to do it, you won’t regret going to a shehane. It’s really hard to beat in the competition world, and has performed really well for me on game as well.

If I do it I will probably do a Walker but close enough.

Cody. I shoot a 20” 300wsm with Berger 200-20x at 2780 with a can. It’s not super fast but is a tack driver. Not sure if this helps you in any way.

I don't understand it either. It's just another maintenance item to add to the list & another possible variable.

I love hunting with mine. Putting in ear protection isn’t always an option when hunting in thick dark timber. I cant stand anything in my ears for extended time and ringing ears sucks.

I do not have a can. I am heavily considering one, but for another reason. One of the main properties I hunt is right next to public land. The other neighboring property is hunted by some very nosey hunters. As soon as I send one, everyone knows. My phone gets blown up instantly with "did you just shoot", "was that you", "what did you shoot" ECT. If I don't answer, they drive real slow and watch from the road. With the competition for hunting property where I am located, I don't want to draw any more attention to my area. Especially with some of the decent bucks I've pulled out of there lately. They also complain when I shoot does. I am a meat hunter first. They don't understand that. They think I'm reducing the deer population and they won't see as many deer.

So if I can put a can on, and reduce the chance of them knowing I shot, it would be better. Then I can wait until after they have left and recover and field dress my deer. Shooting at both the properties I hunt, let's everyone know that someone just shot over there.

Not using hearing protection is just another benefit. I use my OTTO NoizeBarrier's, so it's not a big deal.

There are other reasons a can could be useful.

Here is the thing about the 300 wsm. It will be the most consistently accurate 30 cal magnum you will ever own if you let it. If your used to shooting a 300 rum and are coming into thinking you’ll get some top speeds you’ll be disappointed. From a 26” barrel expect 2820-2850 using 210-215 grain bullets. Powders to use would be H4831SC, N555, and my favorite RL23. Do this and they will shoot like a 7 Saum, and 338 edge
