30-06 with H4985in a M1 Grand

[300 RUM]

Does any one have load data for 30-06 with H4985 in a M1 Grand, I am concerned about bending tthe up op-rod?

My new hornady manual says 43.2-46.4 of h4895 and this is the listing in the service rifle section.

Please use a bullet near 175gr for that load too.


Lyman recommends 150-175gr bullets, and hodgdon recommends starting a 155gr Sierra HPBT at 46.0gr of H4895
a 175gr would start at 43.8gr

The M1 gas system was designed around the burning rate of 4895.

If you want to bend your op rod then use 4350 powder which raises port pressure, causes over gassing, rips the rims off cases and bends the op rod.

Powder burn rate controls port pressure.

Everything you wanted to know about port pressure but were afraid to ask below.

I shoot 200 yd competitions, with 150 gr FMJBT followed by 44.0 gr of H4895. It's mild recoiling, and groups nice. This works good in garands, and awesome in my 03-A3.
