Reloader 22 and Temperature

[TwoTone]

...The loads I'm looking at are 61.5grs and 62.5grs (Load 11582, Load 10438 from Reloaders Nest). Both loads call for Nosler partitions 165grs is there any dangers in switching up bullets, say to a Barnes TSX of equal weight? Would this cause a drastic pressure change?
Thanks again

RL-22 and 165gn bullets are an excellent combination in the 30-06.

There shouldn't be any trouble switching bullets of the same weight.

In my rifle you can't get enough RL-22 in the case to get you trouble with a 165gn bullet, even with a long drop tube and vibration and a very compressed load.

The result is a very accurate and safe load with velocity that you might expect from a 150gn, not a 165.

That is very true, speeds for these loads are 2800fps to 2960fsp (federal vital shock is 2910fps for 150grs).

I was thinking of starting @61grs than moving up in .5grs increments, just to be on the safe side, with an upper limit of 63.5grs if there are no pressure signs. I'm shooting a BSA P17 (M1917) Sporter, so I'm thinking that the pressure should stay within workable limits. Does anyone see where this strategy could get me in trouble or have any ideas on how it could be improved
Thanks

P.S Thanks everyone for your input it has been very informative

Every powder is temperature sensitive but RL 22 and many other Reloder powders are less sensitive to temperature variations. H4831 and some others are better as well. Best advice is to develop your load for the temps you'll be hunting at and practice with it throughout the season so you know how your round is performing.

I tend to agree. It may not be noticed unless the application for which the powder is used demonstrates it as sensitive. Eg. Its ironic but I have never found BLC2 to be particularly temp sensitive but I have had a clear indication that Varget can be. All be it limited to the applications that I have used the 2 powders for.

A "cook-off" can mangle more than just the case We had a 30. cal gpmg cook off during TQ3 in Shilo; cover pieces everywhere. That was on a hot Aug. day. We also had a M109 round ground out about 100m down range during direct fire in the same course. We were real lucky no one was killed never mind hurt in either one.

Steve,
Unlikely to cause a "drastic" pressure change, however, unexpected suprise's can happen.
Although some knowledgable handloaders insist that Barnes X's show more pressure than other bullets, my Barnes #1 manual shows stouter charges than any other data on the shelf. And that for early pre-TSX's too. Go figure.
When changing any component of a warm/max. load, I drop 1 1/2 grains and load 1 each in 1/2 gr. increments back up to the previous. Has kept the nose attached to face for 40 years, and counting.

Some good advise in the ^ posts. And X2 with TwoTone, IMO the worst you could do with 06/R22/165 is loosen a primer pocket. The case won't hold enough of that combo to create serious havoc in a modern, strong action.

Shame to hear of the demise of that noble GPMG, hope it's dismembered appendige's were given a respectfull interement.

Fine as it was .... still no candle to a BREN though.
