338 Lapua & Rl33 - max load for 300gr?

[lte82]

Worked up to 97.5gr rl33 with the 300gr scenar and had excellent results between 96.5gr-97.5gr. 97gr shot right under 1/2 moa with 96.5 and 97.5 right at or just over 1/2 moa. No heavy bolt lift, no ejector marks, primers are still rounded, etc.

Does 100gr sound out of line to work up to next?

Work up in 1/2 grain increments, I have heard similiar/good reports but also heard of some temp spikes so keep it in mind when you reach "today's temp max"
Full disclosure is the test done that I am inferring to is a 338 AI, but I presume the same concerns will prevail.
I'm interested in your velocity report as well as you proceed up.

I'm interested in the velocity too. My magnetospeed finally stopped reading altogether today, so I wasn't able to get any data. =/

I'll keep working up slowly and see where I can get.

Interested also in your results. I will also be doing this same combo soon just with berger hybrids.
