223.load for 65 Gr.sierra bullets

[280shooter]

I have some 65 Gr. Bullets coming.can I use the same loading data for the 65 Gr.as the 63.Gr.loads.
The powders I have on hand are,,h335.h332.imr 4198.h4198.imr 4247. H4227,H 4831,Imr4320

Of the powders you listed I would use H335. H322 would also work well but I prefer H335.

Yes, you can use the load data from a similar profile 63gr bullet. The 2gr difference will mean very little although I probably wouldn't push right up against the max charge weights and for sure not over.

What bullets did you buy that are 65gr?

Both H335 and H322 are by far the best powders for that bullet.

H322 actually gives better case fill for the same pressure/velocity/burn completion,
and would therefore have the greater accuracy potential.

Accuracy is right around 1.25" (100 yds)out of a new Sig Sauer 400 AR ... they have shot the best that I've shot out of that gun ... I have not had time to shoot it much since I got it .... I will be trying that same load in a DPMS Sweet Sixteen that will really shoot(when I can see) ... old eyes !!

I realize the OP ask about the powders he listed ... but since powder is not real easy to find ... I thought that he may cross paths with RL15 ...
