so it appears like it is a bad option for the magnum loads you are looking for since h110 will give 1460fps with 500c.u.p. a lot less force

Accuracy was much better once the load was dropped again a fifty percent grain or so. I've noticed this with both equally 4227 and 2400. They both of those burn up cleaner Using the around max loads.

This can be an older thread, you might not get a reaction, and will be reviving an old thread. Make sure you take into account making a new thread.

Although they say to operate up, I've operate a person with another's data at max in a very .357 Magnum. No problem.

I just spoke with IMR (Hodgdon). I explained to them I possess the IMR4227 built in Canada, but their Website only lists H4227. I requested them what recipes I should use:

OP I really have to question why you require that velocity? I would Imagine precision can be an improved aim than an extra 100fps. By way of example my 223 loads are somewhat gradual but @one hundred yards I've 4 shots touching. My buddies would give me a tough time all through chrono but shut up when they saw my targets.

Not a brand name to relaxation on its laurels, IMR carries on to establish new powder formulas which have been progressively insensitive to weather and temperature alterations, have enhanced burn up speeds, and have additives that remove copper bullet jacket fouling. Foremost the pack in terms of innovation is IMR 8208 XBR powder. This correct metering, Tremendous quick grain rifle powder is great for cartridges just like the 223 Remington/five.56mm, 308 Winchester/7.62mm NATO, along with the 6mm PPC.

What would you imply by “amazing”? If you really look at the Hodgdon data you will see that it's produced in a ten” barrel. You may’t be expecting to attain that sort of velocity with your small four” revolver. How is always that somehow “impressive”?

62mm NATO, as well as the 6mm PPC. IMR 8208 powder is a wonderful option for competitors and hunters when precision, imr 4227 load data power, and dependability suggests the difference between hitting your mark and going for walks away vacant-handed.

On some guns, the brief circumstance can only IMR 4227 snap out from under the extractor if applying a continuing tension IMR 4227 spring form ejector. A chance to shoot an array of bullets is a combined blessing. Should you aren’t concerned about currently being on the leading edge of accuracy, the rapid twist needed to stabilize the heavier bullets, suggests you're spinning the lighter loads way much too quickly. This may lead to inadequate precision from lighter loads. Remember the fact that the benchrest crowd, the recent-rodders of this Activity, feel the ideal accuracy is on the edge of stabilization.
