In this FN Mauser .270,I'm using 59.8 grs of RL-26,Federal 210 Match primer and a 150 gr Nosler Partition. Getting 3010 fps from the 22" barrel.
I never got 3000 fps w/150s in a 270 BUT I did get -2950, so I doubt it's worth the effort. Good job to you Ken. Jerry

I'm happy with 2900fps from 150s out of a 23.5 inch bbl. Currently using 150g Hotcors. Those things penetrate like a mo-fo! In a wet newspaper test they out penetrated 400g Speers out of the 45-70 and 180g Interlocks out of the 30-06.

It was Fred Barker, in an article in Preciion Shooter maybe a decade ago, that started me trying Mag Pro, RL25 in the 270. Fred also used MRP II and some other newer slower powders in a 25" PacNor barrel on a a Mauser action.
He said we were missing the boat with the 270 by not trying powders slower than H4831. I think in terms of velocity with the stuff 140 and heavier he was right.
And guys using theses 165-170 gr VLD bullets will find that out shortly I think.
The 280 Remington is overbore.
The 7 Rem Mag is over bore.

Yes Bob the 1-8 twist 270s are the next horizon. Heavy bullets; less muzzle velocity; greater downrange energy.
Good call mate.

Even a M70 in 270 Weatherby. Do you have a pic of one recovered from the wet lap test? I'd like to see it. Hot cores have always been a favorite of mine.

I'm happy with 2900fps from 150s out of a 23.5 inch bbl. Me too. I get a bit over 2900 but close enough (24" brl). That extra 50-75 ft/sec makes an 1" or so at 500 yards. I'd rather keep my face intact rather than chase the last 50 ft/sec.

I love the old rifles. It seems more and more these days. I've come full circle again and just bought another m1917 yesterday. You gotta love those old Mausers, pre 64's, m1917's, and springfields.... Good thread guys. I'm surprised at some of these velocities you are getting with the good ol 150 gr. partition though. I've made up my mind, that's the only bullet I'm going to run in my 270. Until something changes my mind I guess...
I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style. You want to see an animal drop right now? Shoot him in the ear hole. BSA MAGA

RL26 is very good in my 7 WSM and 270 WSM. Plenty of speed and very little if any compressed loads. If I had a 270 Win I'd try it with 150's first. I've had good luck with it so far.

Thanks for posting those. Looks good. Man that big Speer .45 is a whopper.
