Home Forums Reloading Big Game Rifles 22 hornet loads

Thanks Sem and Dfarmer. powdr

I just read that Power Pro 300-MP was the same as H-110 and W-296. I knew the latter two were the same powder, first I heard about 300-MP.

Anyone know if that's true or not?

DF

I sincerely doubt it. All the data I've seen for H110, whether in the .22 Hornet or handgun cartrdges, is considerably lower that the data for 300-MP.

The granules are very similar in size, but 300-MP is much grayer in appearance than the black of H110.

Both powders are made in the same factory, and probably are very similar in make-up, but am guessing 300-MP has a different coating to burn slower.

Thanks, John.

You can read about anything on the internet, didn't really believe it when I read it, just wasn't sure.

Posted on the internet doesn't make it true, doesn't mean it's false, either.

What you said makes sense, there is a difference in appearance.

I use 1680 and the Midsouth 34gr. HPs on top of Rem. 6 1/2 primers in my Hornet. I haven't chrono-ed it, but it shoots well, and I have other rifles if I want 'faster'. For my needs around here, that bullet's BC doesn't hurt me, ranges are short. The bullets are CHEAP, which allows a lot of practice, too. I use Sierra 40s, and other "Hornet specific" bullets, when I can find them, but never anything heavier than 45gr. No plastic tips, either, I have other rifles for that, like a .221 Fireball.

I barely touch the cases with a FL die, sizing maybe, MAYBE a 1/4" of the case neck (no lube needed) and after loading and seating, I use the LEE factory crimp die. It seems to help ignition and makes the groups "rounder".

They fit my little CZ 527's magazine, too.
. I seat the bullets as long as possible for working thru the magazine, or as short, depending on your point of view.
All in all, it's a fun little package. I work with what I have, I know I could do better with the 40 BTs and single-load, but I miss sometimes, and a second shot ain't a bad thing.

Powdr,

I need to revise my post.

I did some research on Load Data. They have 55 gr. loads for the Hornet and K-Hornet.

No data for 60 gr.

Some 55's are pretty short and stubby, which as you know, length is the critical value for twist.

Some data used 16 twist, and although they didn't mention accuracy, they did publish loads.

With 55's, seems around 2,100-2,200 fps is max and top loads were with H-110 and Vv n-120.

In the K-Hornet, there was one load for 55 gr., 13.5 gr. RL-7, Rem 7 1/2 primer, velocity around 2,500 fps.

So, maybe 16 twist will work some 55 gr. bullets if the bullet is semi spitzer, doubt it would work with a sleek, long bullet.

DF- I've been loading Sierra 55gr SMP's for years in a 14" Ruger. Load is 12.5 gr of Lil' Gun with WSR primers. The SMP is the stubbiest 55 grainer that I'm aware of. You might try it with a 16" twist and see if it will stabilize.

My first .22 Hornet "rifle" was a T/C Contender carbine barrel with a 1-12 left-hand twist. With 10 grains of Li'l Gun it shot the 60-grain Nosler Partition into considerably less than an inch at around 2400 fps.

That 12 twist really helped.

Wonder how those 60 gr. NPT's would work in a 14 or 16 twist?

DF

In my experience they're marginal in a 14 twist even at .22-250 and .220 Swift velocities. I heard when the 60 Partition first appeared that it was designed primarily for the .223 Remington, and at the time the standard .223 twist was 1-12.

I remember Gunner500 shooting 45 gr TSX in his vintage Super Grade Hornet. My 16 twist CZ Hornet keyholes them.
Gunner checked his twist and the vintage Winchester with cut rifling measured 15+ twist. Seems that tiny bit of extra twist was just enough to stabilize those bullets. His target shows clean round holes, no keyholes and good accuracy.

The 45 gr TSX is around .69" long, IIRC. So bullets must be shorter than that for 16 twist.

DF

Yeah, twists tended to vary a little more when factory barrels were cut-rifled, primarily because sine-bar rifling machines were used, which are infinitely adjustable for twist-rate within their upper and lower limits. But they need to be checked and adjusted now, and depended on operator competence. Have mentioned this here and there before that I once owned an old Savage 99 in .250-3000 that drove me nuts for a while, since it averaged around 3" with 100-grain Speer Hot-Cors, and they've always worked for me in 1-14 twist .250's, since they're probably the shortest 100-grain .25 spitzer around. The bullet holes in the targets didn't show any sign of tipping, but accuracy sucked.

Well, after trying a bunch of stuff I finally measured the twist, and it was right around 1-15. Switched to 87-grain Hot-Cors and groups immediately shrank to 1-1/2"--and that was with iron sights.

The trouble with rifling twists that are just enough to stabilize bullets, however, is if elevation or temperature get much lower, accuracy goes south.

shortly will be shooting these!

Well, went out yesterday with the CZ hornet.

No 35 gr Vmax did really well but I did get one great group at 100 with the 40 gr Semi sptz Sierra at 2775 fps and 13 gr LILGUN. Velocity was a little disappointing. 4 shot group

That is K-Hornet

You by-God got it now Fotis, that will work.

I am happy too, but I have over 500 of the 35gr v-maxes now with no use! LOL

HMMM maybe in the other CZ 527 the 222 rem..... for short range use??????

[quote=Fotis]

I use the 35 v maxs for blue dot 223 loads. They are perfect for short range plinking.

That and Hornet data, too.

Lots of info.

I like your Hornet load and agree with gunner.

That'll work...
