I have IMR 8208 and LT-32, I want to use it for 22BR. I can not find any grain data for any bullet. Can anyone help?

The Sierra phone app has load data for the 22br Norma.

I have a couple of 22BR rifles that I shoot the old Hornady 75gr A-Max bullets in with 28.8-grains of Varget.

The Sierra Sixth Edition Manual is showing an 22BR Accuracy Load of 32.3 grains of RE16 for the 65gr to 69gr bullets.

Here is information from the Sierra 5th Edition Manual:

Use n135 data.

I'ma like a broken record with BLC. It's been great in my 22BR up to 55 gr. bullets.

But-- I have had great luck with IMR 4895 -- just doesn't go through the measure as well.

My barrel is a 1 in 14, so I don't go heavy with the bullets. jd

As others have said, 4985 and N135 are similar. 8208 is a bit faster. I have found that AR Comp, Tac and AA2460 to be very close in data as well.

When I switched from AA2460 to 8208 in my 7TCU so that I could get a bit more temperature stability with my IHMSA loads, I ended up with a charge of 0.2 grains difference between the two.

8208 is fantastic in a .22 BR!

Benchmark and the 50s & 55s work the best in my 1-12 22BR.

The Sierra online manual app lists IMR8208XBR for bullet weights up to their 63 gr SMP. No loads for that powder 65 gr and up.

No knock on anyone but the print manuals are outdated. The app, IMHO, is the best way to go with Sierra bullets.
