150 gr Sierra Game King bullets for .30-06

IMR 4895, and 4064 are very popular in that range, among many other offerings from Hodgdon
Sierra lists a COAL of 3.225" for 150gr SPT's,
4064 - Start 44.9, Max 52.1
4895 - Start 44.5, Max 51.7

I don't have experience in loading for the 1100 actions. Others probably do. With other semi auto actions, you want enough gas to reliably work the system, but not so much as to overwork the action.

I'd go with a 165 and up. Never had good luck with 150s from a 06.

I purchased some 150 gr Sierra Gameking bullets. I plan to use one of a few Hodgdon powders I have on hand, but the Hodgdon web site only lists 150 gr Nosler E-tip and BT and the loads are pretty different for the two bullets. Does anyone have any data for the Gameking? I'll be using them in a Remington 7400 semi-auto.

Use the b tip data, start low, you'll be fine

Sierra 5th edition suggest a OAL of 3.225" for that bullet (#2130). Powders are plentiful, IMR-4895, 4064, 4350 just to name a few.

Ya 150s shoot good, I like the 155Ajax in my 308 wish I had more. But for game the 150s tend to be unreliable.

150 dont look stream line like amax rear tail seems longer

The 150 grain Sierra GK is great in a 30-06. For IMR powders I like 51 grains if IMR 4064. Also, 57 grains of IMR 4350. These are bolt action loads so you may want to back off a couple of grains with a autoloader. The 4064 load is very accurate and gives high velocity with light felt recoil. The 4350 load is high velocity but the recoil feels greater. Try the 4064 load first. Set the base of the bullet even with the back if the case neck. Overall length 3.210. I am not a fan of IMR 4895 but it is popular with tthe M-1 Garand. On this powder I would start with 47 grains and work up maybe to 48. Pressure on this powder comes up really fast, faster than 4064.

I wouldn't use E-Tip data, or for 150 gr RN bullets. But the data for BT's or most other conventional cup and core bullet with a pointed tip should be close enough. As always you need to work up loads and you might find some minor differences as you approach the max loads listed.

And you don't want to be trying to work with max loads in an semi auto anyway.

Try 57.0grs IMR 4350 or H4350. I consider this a maximum load in my rifles, it pushes the bullet above 2700 fps. The load pictured, is above max. Everything worked fine at the 100 yard range, but I had leaking and blown primers when I went to CMP Talladega. It did shoot well.










Different rifle, with the 57.0 grain load

Many years ago, I was working up loads for a M1 Garand 30/06 using H-335 / WC -844 using a 150 grain Winchester SP/FB. I found some loading Data on the web which recommended 49.0 grains with a 150 gr. bullet. I loaded up a few rounds in Lake City 1960's GI brass. That load was way too hot, stretching primer pockets, making the brass unuseable.

I re-tested and found 46.0 grains was a good, accurate load in that brass and rifle. Lesson learned. I can't imagine touching off 50 grains with a 155 in 111º temps.
