220 partition in 300 win mag

[kawasaki Robb]

Hi everyone, I'm new to the forum. On the 7th of this month I'm heading to Idaho for a pack in DIY Elk hunt. At first the area I was going to be in, was going to have mid-range to long range shots. 200 to 550 yards. But just found out, the shots are going to be MUCH shorter. 80 yards will be considered long, due to how thick the timber is. Anyways, I decided maybe an old school round nose in the 220 gr class might be cool to use. After doing some vetting and setting most of the bullet can't take the velocities my 300 win mag would be throwing them at. I came across an old thread that Guy Miner posted about the 220 partitions in his 06. I started thinking those would be awesome. I was able to pickup some factory seconds for a great price. Anyhow, picked 3 powders to try, IMR 4350, IMR4831 and decided to try RL26. I tried RL26 because I had a pound of it still. But I've never been able to get it to group. I loaded all three, no they are not sanctioned through Nosler or rokside or probably anybody else. Yes they are warm. But I just got back from the range, to say my tikka likes those 220's is an understatement.
I made the mistake of firing 5 shots on the first group. The 4th and 5th shot the thin barrel was hot. But shots 1-3 measured .339" and .952 with all 5. The lower right is RL26 and left is IMR4831 all 3 shot groups. I cleaned the gun after each group. I wish I hadn't now, but after the first clean fauler shot. The 2nd and 3rd shots were touching. Either way I'm happy with the groups. And the fact the tikka likes those 220 partitions

Welcome to the forum, Looks like it’s going to be warm. I learned to hunt elk in the Blues, Northeast Oregon. As a kid I carried 220s and 180s in my 06. I would switch out when hunting the thick timber, go to 180s on open hills. They, 220s work just fine.
I just got back from Idaho, I’ve a blown out knee so kept busy glassing and driving our crew around dropping off and picking up. The elk we saw were all on north facing slopes, as high as we could get and still have water nearby.
Very little bugling going on, cow calls were effective. There has been a week of relatively cold nights and it sounds like things picked up with the rut activity. Take a cow call.
Good luck, with 80 yard windows the 220 will hammer elk. We saw bears every day, one of the guys tagged one.

I got 2854 with IMR4350, 2760 with IMR 4831 and a screaming 2940 RL26. I've been pick at the brass right now. When I shot the first RL26 load and saw the velocity. I thought oh God. I was really expecting a tight bolt, cratered primer or even the primer falling out. To my complete surprise, the bolt opening easily, and none of the cases had cratered primers or even ejector marks. I might go with the 4350 because it's getting the velocity I like and the first three shots were very tight

That 220 will work up close and I’d not be worried to stretch it some as well. Should be a hammer. Good luck!

I have oal at 3.4" and it fits in the tikka magazine. How could you not think this a sexy looking round

 

[kawasaki Robb]

I'll let everyone know how i do and how the round does. But like you all were saying. I think I'll be just fine

Was it pretty warm when you were up there? The guide who's packing me in. Said that during the archery season, they were into elk everyday, it was just so thick they just couldn't get a shot off. They did get a bull from 12 yards and another guy ended up getting a bear.

My favorite load in the .300 Wn.Mag. is the 200 gr. Speer Hot core. I run it at close to 2900 FPS using a long discontinued Winchester powder. Brass is Winchester with WLR primer. I have four rifles in .300 Win. Mag. One is a "B"model and three are "S" modlels which I prefer over the "B" I also have a Walmart special Winchester M70 which is the one I took an elk with. The shot was measured by laser to 530 yards. One and done DRT. FWIW, that was the longest shot I've ever taken on a game animal. Frankly.I'm not in favor of long shots, much preferring to see how close I can get. Circumstances for the area were I made the shot were the elk were in very wide open parks and just a bit on the spooky side,
