Home Forums Hunting & Shooting Custom Rifles & Wildcats Favorite bullet in 6x45???

I'm thinking about building a 6x45 on a short rem 700. I know there are a lot of 6x45 fans here so I was wondering what bullet you guys like. This will be mainly a coyote rifle with maybe the occasional youth hunter using it to shoot something. I'm kinda leanin to the 87 grain v-max. My tentative blueprint will be a #5 twisted 1/9" pacnor stainless cut and crowned at 21" in laminated vls stock. Let me know what you think!!

Would work well. Don't overlook the 70gr TNT. You can expect 2900-3000 w/87s, and 3200 w/70s.

Had a TCU....aka 6x45 AI, 21" 12twist, did ok up thru 85 BTHP, but preferred 70s in the slower twist. You will do well w/9 Twist in that round, should handle thru 100s fine.

FYI, H335 and AA2015BR worked well in mine.

I have been running one through the gauntlet almost identical to your components above. 1:9, 21" on a Howa action.

I got no where near the speeds 65BR is quoting.

I did 2900 with a 75 Vmax, 2700 to 2800 with the various 80 grain soft point offerings as well as the Sierra 85 GK, and 2850 with the 70 Nosler. The 70 Nosler has a larger bearing surface which is why the 75 Vmax went faster I think.

I got 2750 with the 80 TTSX as well.

I tried each bullet with H4895, H335, and Ramshot TAC. My rifle is long throated so on top of the speeds I got, I was able to seat the bullets as far out as 2.52" to maximize powder capacity and still got the speeds listed above.

I settled on a 80 grain Remington SP at 2800 for my all around load with H4895. The 75 Sierra HP is a very tough bullet at 6x45 velocities.

If I was strictly after varmints, the 75 Vmax at 2900 would get the nod.

Send me a PM and I can get you some extensive load data for the 6x45.

I use mine as a coyote gun exclusively and run 55gr NBT's and BK's.

Here's a link to more load data.

That's the info I would have emailed the OP...

Thanks Erich.

What velocities are you getting with 55's and what's your barrel length?

Appreciate it fellas! Greg, how explosive was the 75 V-max at those velocities? Did it tear dogs up bad?

I didn't shoot a coyote with the 75 Vmax. Sorry. The 75 Sierra HP will most likely pass through a coyote. I've shot about 8 of them with it and they've all passed through. I've shot a few with it and cannot keep this bullet in a deer either. The 75 Sierra HP would be a good all around bullet IMHO. It is accurate and cheap as well.

Are you trying to save fur? If so, I'd go lighter than the 75...

For killing, I'd go 75 for sure. It was a very accurate bullet for me with all three powders at about 2.48"...

My 6x45 has a 21" 1:9 twist barrel as well and loves 95gr. Berger VLD (hunting) with H322.

Could be pressures spike quicker in 9 ROT vs. the 12" I had....what speeds do you see, if you have clocked them?

BTW, I believe I used commercial brass for more capacity and speed. Greg, you running mil surp?

I have a PH buddy in RSA who has used his with 85 grain Nosler Ptn's with good success on impala and warthogs. He also likes the barnes x I think either 80 or 85 grain. He has knocked over a few kudu with those. He likes to loan the rifle to kids and lady hunters who usually get better results than their spouses/dads.

I'm running R-P...

Think it might be something to do with the longer throat?

Appreciate all the info guys! I think it's a really neat cartidge and with Black hills supposedly starting to load for it maybe we'll see it make it to factory status. to me it's alot better than all the copy cat rounds that everyone is coming up with...but what do I know.Thanks again!

Saw recently on Sniper Hide that Corbon is set to come out with 4 factory loadings as well

Greg, may be - throating does affect pressure/speed, no doubt.

If this round came out during the time the 223 did, it would be interesting to see where things would be today, i.e. favorite twist, weights, etc. as no doubt it provides more mass than a 22 cal, and works in AR platforms as well.

65BR,

I might have just had in my head a number I was trying to get to that was a little too optimistic.

2800 with an 80 grainer from a 21" tube for a non AI'd .223 parent case is not too shabby...

Not at all, doubt the AI/TCU version gets that much more, very little diff in capacity. 2800 or 3k, either will get it done on varmints thru deer w/placement. 200 fps either way won't change the outcome IMHO.

They are neat lil 6s just as Layne Simpson wrote about long ago, I wanted one after reading his 'little 6s' article. Good stuff on the PPC/BR/x45/TCU, etc. I think Fadala had a 21" or so in 6/222, using BLC IIRC, he claimed 3k if not mistaken, but I'd be he was twisted slower, 12 perhaps. Not sure if a 14 would do for an 80, even FB. Perhaps. The 85BTHP was at the upper limit in my 12 for stability/accuracy. I'd build nothing but an 8-10 ROT if I did another. I never want my twist to limit my options.

I am shooting the 58gr Hornady Vmax using Imr4198 getting 3400 FPS. I built it on a mini Mark X action. About as accurate a rifle as I own.

Have a barrel here to bore out to 6mm for either a 6x45, or a 6x47. I had a 6x47 40 years ago in a benchrest rifle configuration, 10.5 pound weight class.
It had a 1-12" twist and I used 70 grain bullets of the day with 748 Powder and got excellent accuracy.
Not sure I'll go fast twist with the next one. I'm a slow twist fan, so 1-12" sounds good again, with 68 gn bullets available from the benchrest shooters making them.
I kind of hated having the 6mm PPC come on line as I sold the 6x47 and bought the PPC, and I did love that 6x47.
Today, I could go either way, 6x45 or 6x47. Case capacities are close to each other.

I got the 85 Sierra GK to 2800 as well.

It sure is fun to shoot though and burns 26.0 grains of powder to get 2800.

Thanks for the thoughts...

What I loved about my TCU, it was SO mild in report and recoil, and very little muzzle lift. Should have been a Saami, just like the BR IMHO, they were never mass produced in production run rifles, which was good for the custom barrel companies and smith's.
