I want to stay 2800-2900 feet per second. The Hornady Reloading
Manual says 51.6grs, so that's what I'm going to try to be on
the safe side.

I have never tried the "Reloader" type powder in any of my rifle loads.
The data did look promising but just had too much other powders to buy it with all the IMR , Win. and Hodgdon powders on hand.

Good luck with that R-19 powder.

shooting a win. 270, not the WSM but found the Barnes 110 TTSX with reloader 16 to be very tight shooting. Needs about a .125 jump in my 24" barrel, running 3160. Can shoot under 1/2" at 100 yds. The RL 16 is temperature stabilized, meters well and shoots clean.

My 3 test reloads with Alliant Reloader 19 went well. The target
group was; 1st on center, 2nd threw a little to upper left, and
3rd damn near in the first bullet hole.

135gr 270 (.277dia) HPBT Sierra #1833/51.6grs Alliant Reloader 19
/CCI LP #200Win Brass/COL: 2.875/2800fps? Crimp is just a
light bump.

I used my 10th Edition Hornady Reloading Manual, and just picked
2800fps for my test reloads.

I would say that Alliant Reloader 19 will work perfect in my
270WSM and my other Rifle Cartridges.
