Anybody out there using this combo?

I'm thinking of using my 300wm as a 270wby for deer hunting beanfields.

Any loads, tips, or experience to share?

If I can't get accuracy at 3300fps+ then I'd rather stick with my go to load of 180grn hornady @2960fps.

I came accross a few of the regular tsx's in my inventory today. A check of my barnes book showed 78 grains of h4350 as fast and accurate. My quickload program thinks that's gonna be pretty hot but I have freebore in my tikka which usually buys me about 1.5 grains of max. I'm gonna load up some at 77 grains and go to the range tommorrow with the chrono. Any signs of pressure or crazy velocity and I'll quit. I've seen some guys pushing these at 3700-3800 out of rum's with good accuracy. Hope I get the same results.

I shot the 130 gr Barnes boattail (moly coated)in my 300 Win Mag for several years until my supply ran out. I was shooting a full case of WW 760 and getting 3600 fps in my rifle. Accuracy was usually about .75 MOA for 3 shots, 1.25 MOA for five.

The load data is in the second Barne's manual. I have some 130 gr. TSX to try next with that load.

Thanks, good info.

I have a buddy shooting the 130's out of a 300 shortmag, and he loves the combo.

I hunt big ag fields in north MO, and think this combo could really match up well with some of the extreme ranges that I look over every year. Even with the flat trajectory, it would have to be a perfect situation for me to shoot to 350yds or over. With that bullet and speed though, the bullet drop at that range would be cut in half compared to my standard 180grn load.

I got to the range today with a small batch of 3 bullets over 77 grains of h4350.
TSX 130---shot very good but had one flyer 3380fps
125 sierra flat base...shot about 1.75moa 3390fps
125 moly coated barnes xbts (older bullets I had on hand) shot poorest of all 2 moa. 3340
fps.
I think I'll get some 130 ttsx's on order to play with a bit more. If you are looking at my data remember that my gun has alot of freebore. Looks like I can work up and perhaps play with something like re17. Quickload thinks that about 3550 fps should be easily achievable with several powders.
I think I'd also like to play with these in my '06 and 308.

i checked that Barnes manual and they list 3481 with that load (76.0 grains of 760). My chrono was always 3600. I can't find my notes to see if I worked up past that load with the moly coating. But the manual lists 3604 fps with 78.0 grains of H4350.

My 300 is a Colt Light Rifle with a slim barrel. I think that's the only reason my groups' averages change that much between 3 and 5 shots. I don't wait for the barrel to cool much between shots on a field gun because I doubt the game will wait for that. If the first two are touching or close to it every time, I'm a happy camper.

Out to 400 the 130 may be optimum, but its poor BC will catch up with it fast.

Agreed! I liken it to a heavier version of the 257 Wby in that at normal hunting ranges the speed and energy are very effective.

sure enough.. but 400 yards is PRETTY close to 1/4 mile .. that's a long shot for a hunting rifle

i may have to try some of these in my 300 ...

Jeff, the downside is they are NOT meat-friendly! Shoulder shots will ruin the on shoulder and usually most of the off shoulder as well. I use them to brain-shoot and for varmints of the larger size.

Harry - I was thinking head shots on piggies!

i wanna see a .308 ttsx with all the petals blown off!

Past 400yrds or so I don't care about trajectory, and wouldn't mind a bit if the bullet stopped in mid air at 450yds and dropped to the ground. I'd never know the difference as I don't intend to hunt at that range.

2" high at 100yds, and 3" low at 300yds sounds very inticing though. Should be around 13-14" of drop at 400yds. I avoid shooting shoulders if I can.

Seeing if I can get these 130's to shoot will be my next project anyway. 3,400-3,500fps with controlled expansion and accuracy would be bliss.

I was getting 3480 out of them with Varget and shooting easily into an inch. The hodgdon site has a good load for it.

We shot 7 last year with the 130 TTSXs, mostly out of '06s All one shot kills, none went further than a jump or two. I don't think there's a better bullet for whacking Bambi.

How about out of a 308?

A 308 with the 130 Barnes TTSX will like 44-46 grains of Varget for the most accurate load.
