7mm rem mag.
im working up loads with 120gr nosler BT's. i dont need max FPS.
H4350, IMR4198 (based of of tons of research and already testing, it works.), & varget.
now, 4350 & varget have hodgen data for up to 130gr.
What i want to do is make some powder fouling shots / fire formers with some spare bullets i wont be using, but they are 150gr. apparently when switching powders theres an accuracy hit for a couple shots. im trying to eliminate that issue, without having to use the very hard to find expensive 120's.

Finding out whats really possible, not just by whats been vetted in a published book, is what im after.

i have gordon's & quickload.
awhile back when i first started using QL and was more trusting of it, i made some 4198 150gr foulers. (modern reloading pg 285 38.5-43gr)

Im a little more leery about doing that now that i have learned a bit more, but maybe someone else has tested it.

are these programs accurate when estimating varget and 150gr pills as far as pressure goes. S.E.E. is definitely a concern since im around that 70% fill mark.

Varget is slower burning than 4198, so the chance of SEE would be greater is what i read.
